How Sorbead India is Contributing in the Oxygen Production during Covid-19 Pandemic?
How Sorbead India is Contributing in the Oxygen Production during Covid-19 Pandemic?
07, Jun 2021

These times seem unfortunate and difficult amid the COVID-19 pandemic. There has been an imperative need for Oxygen to fight against this predicament. No one ever imagined such a situation where health industries would encounter such a massive scarcity of Oxygen.

To provide for the needs of health industries, our team at Sorbead India has united and prepared to contribute to this noble cause and supplies these products 24x7. We have constantly been in touch with the various manufacturing units and government bodies for their urgent Zeolite Medical Oxygen Grade requirement. Our technical experts are actively sharing their expertise on how our products can be used in oxygen concentrators.

Sorbead India is a prominent supplier to pharmaceutical industries and engineering industries since 1996. In addition, Sorbead India's molecular sieve (Zeolite) is being provided to many Oxygen generation plants and government bodies.

So, what is the role of Zeolite in oxygen generation? Zeolite is an element used to assimilate the Nitrogen present in the air to provide oxygen-rich air for the patients and industries. The oxygen concentrator's molecular sieve is used for the absorption of all the gases. The principle of Rapid Pressure Swing Adsorption is used here where the Nitrogen in the atmosphere gets intercepted by the Zeolite Oxygen Concentrator present in the molecular sieve. Such a type of oxygen generator is typically used in healthcare applications. A molecular sieve for an oxygen concentrator is used to absorb all the gases and group them by the molecules. An air compressor is provided in the molecular sieve oxygen concentrator and two different cylinders that have Zeolite employed on the oxygen concentrator.

Furthermore, there is a container for balancing the pressure. It is important to know how to use an oxygen concentrator if one wants it to work accurately. Zeolite helps in separating the Nitrogen component from the air present in the oxygen concentrator, which later remains only the pure Oxygen for breathing in the portable tanks. It is majorly used for people who need medical Oxygen because of their low oxygen level in the body. Besides the medical industries, oxygen concentrators are used in industrial sectors, too. People buy Zeolite for oxygen concentrators so that they can use it in oxygen generation plants. The product especially has its use in the medical industry for patients. As there are different oxygen supplies available in the health facilities, the patients often have to suffer the problems due to the shortage of resources, poor electricity, and other challenges.

On the other hand, the medical oxygen concentrator presents a very economical and sustainable source of medical-grade Oxygen to the patients who need it. With the help of an oxygen concentrator, the patients can easily have access to medical Oxygen. An oxygen concentrator is a portable oxygen machine that will draw air and then pass that air into the molecular sieve desiccant and adsorb Nitrogen from the air and give fresh, pure Oxygen of purity up to 95%. Therefore, it is necessary for people to realize the significance of having Oxygen in medical centers. Furthermore, there is a need for safe administration of Oxygen, and this is where the molecular sieve oxygen concentrator helps us out.

Why Zeolite Oxygen Concentrator? There are many reasons for 'why,' and they are as follows. First, it has a shelf-life of up to two years. Thus, it can be used for a good period of time and can also be stored for later use. Second, it can produce Nitrogen up to 5 LPM, 10 LPM, 15 LPM (Litre Per Minute) in a go. Using it is not quite a task as it works on a simple, rapid PSA (Pressure Swing Adsorption) principle that helps absorb Nitrogen from the molecular sieve. The molecular sieve for oxygen generation gets effective after the usage of the Zeolite oxygen concentrator. It gives pure Oxygen after the PSA. It is found to be an effective approach to generate Oxygen even in hospitals. Finally, it has a variant of the portable oxygen concentrator, which makes it more reliable and effective. Zeolite is a booster in oxygen generation and does give help to the molecular sieve for oxygen generation to be precise about the product.

Sorbead India has technical expertise in Adsorbent since 1996, tries to go beyond, and continues to serve. Providing what is needed now is quite a mission, and Sorbead India is ready with the products that can help regain health and save lives in the outburst of the worst of the pandemic.

10, Jul 2020

What is a rectified spirit?

Rectified spirit is a mixture of ethanol and water that is formed by the repetitive distillation process. It contains 95% ethanol and 5% water. Rectified spirit can also be found to be a highly concentrated form of ethanol. It is also otherwise called as rectified alcohol or neutral spirits. 

 

How to convert rectified spirits to ethanol?

There are various processes used across the world to convert rectified spirits to ethanol. Generation of absolute alcohol involves employing the separation technique by using molecular sieves. By adding molecular sieves into the mixture of rectified spirit, this separation of water is easily possible.

The usual procedure is to add 3A type molecular sieves into a mixture for 12 hours.

Molecular sieve is an excellent desiccant that is used in the major industrial application for the moisture removal process. Being crystalline metal aluminosilicates, molecular sieves have a 3D interconnecting network that adsorbs water molecules into its cavities. These silicate compounds contain small pores of uniform sizes that traps vapour and other gas molecules easily. Based on the pore size, there are various types of molecular sieves such as 3A, 4A, 5A and 13A.

Removal of CO2/H2S from Bio Gas using Molecular sieve13X
Removal of CO2/H2S from Bio Gas using Molecular sieve13X
10, Jul 2020

Moisture, Carbon dioxide, and hydrogen sulphide removal from natural gas are crucial to achieving perfect purification. These contaminants can affect the functionality of natural gases. Gases like CO2 and H2s are corrosive, flammable and toxic. In some of the industrial manufacturing processes, these contaminants can be generated as a by-product or by other means. Thus, removing them becomes crucial.

Molecular sieve for Biogas purification and bottling plant

A whole biogas plant consists of generation, purification and bottling units. The purification unit consists of a pressure swing adsorption unit that adsorbs gases selectively. The mesh-like networks of molecular sieves trap the gases into their cavities. Selective adsorption is achieved from the variation in the gas pressure. Molecular sieve for carbon dioxide removal hydrogen sulphide removal is one of the most used methods in the oil and gas, petrochemical and sugar industries.

Pressure swing adsorption

Biogas up-gradation plants use the technique called pressure swing adsorption or PSA that majorly comprises four vessels filled with molecular sieve pellets or beads. All four vessels alternate their operations. At a point, they can aid in the adsorption, regeneration, pressurization or depressurization process. These desiccants successfully adsorb the moisture, carbon dioxide, nitrogen and hydrogen sulphide from the natural gas stream. Upon adsorption of these gases, the methane or CH4 is then let outside the unit as the product.

In the pressurization phase, the pressure achieved by bringing the pressure to equilibrium and injecting raw biogas. The adsorption phase is all about the removal of CO2, H2S, N2 and moisture. Equalizing of the pressure of the adjacent vessel brings forth the depressurization phase. In the regeneration phase, by purging gases into the bed of desiccants, it is regenerated from the saturated phase.

How much moisture can molecular sieve adsorb?
21, May 2020

Molecular sieve, a highly porous material made up of alumina silicate is a powerful desiccant. This desiccant is used by major industrial application such as the petroleum industry for drying moisture content in the gas streams. In this article, we will understand the adsorption capacity of molecular sieves and its type.

Types of Molecular sieve desiccants and their formation

Molecular sieves are available grade. Namely, molecular sieve 3A type, molecular sieve 4A type, molecular sieve 5A type, and molecular sieve 13X type, it is differentiate on basis of their structure

Type A have three grade 3A, 4A and 5A and type x have 13 X having a pore diameter of 10 Angstrom. The adsorption capacity of each type depends on the pore size.

How much water/moisture can molecular sieve adsorb?

Molecular sieves are unique structured crystalline aluminosilicates that have ionic forces built up in it due to the presence of calcium, potassium and sodium. Thus, causing stronger adsorptive forces allowing water/gases to separate. Experts suggest that at a temperature of 25 °C and 10% relative humidity, molecular sieves can adsorb water molecules to almost 14% of its weight.

Molecular sieve type 3A adsorbed 19-20 % w/w and type 4A could adsorb 20-21 % w/w. Molecular sieve 5A pellets or beads can adsorb 21-22 % w/w whereas 13X type can adsorb 23-24 % w/w.

Regeneration process of molecular sieve

It is important to reactivate the molecular sieves before use. The molecular sieve can be regenerated in the following ways:

  1. Regeneration through thermal activation at the temperature ranging from 175 to 315 °C.
  2. Pressure change process.
  3. By using a carrier gas and conducting the heating and purging process.

Role of Molecular Sieves in Oxygen PSA Generators
Role of Molecular Sieves in Oxygen PSA Generators
20, May 2020

There are various techniques used to separate oxygen from the air. One of the prime techniques used in most of the industries is the pressure swing adsorption or PSA.

Pressure swing adsorption is an effective method of oxygen separation that produces good quality gas better and cleaner. In this article, we will understand the PSA process used in oxygen generators and the role of molecular sieves in it.

PSA oxygen generators

Raw air is a mixture of multiple gases. A lot of medical and industrial procedures require a pure form of oxygen gases. This can be done by separating oxygen from the ambient air which contains 78% nitrogen, 21% oxygen, 0.9% argon and 0.1% rare gases. PSA procedure used in oxygen generators uses molecular sieve desiccants for the oxygen separation.

PSA is a technique that works under the principle that as the pressure increases, more gas tends to get adsorbed to the surface. As the pressure is reduced, the gas releases. This principle is used to separate gases from a mixture.

Beginner's Guide For Selecting Adsorbent For Your Industry
Beginner's Guide For Selecting Adsorbent For Your Industry
26, Feb 2020

An adsorbent is a chemical substance that adsorbs moisture and holds it like a magnet on its surface. Every adsorbent works specifically and addresses the needs of a particular industry. Following is the list of adsorbents for your industry:

Silica Gel

Silica gel is one of most commonly used adsorbent that consists of nano-porous Silicon Dioxide (SiO2). Silica gel comes in the form of glass beads and its nano-porous structure provides large surface area available for the adsorption and hold moisture up to 40% of its own weight.

Silica Gel is a highly activated adsorbent, furnished in a wide range of mesh sizes to suit various industrial applications. It is non-corrosive, non-flammable, odorless, tasteless, non-toxic, and chemically inert. It comes in two variants:

  • Indicating silica gel which visually signals when desiccant needs to be recharged or replaced as it changes color when it becomes saturated with moisture.
  • Non-Indicating silica gel, it means that when the silica gel adsorbs moisture, it will continue to be white. This kind of gel you find in the small packets when you buy some products.

Silica Gel is a good adsorbent for HCl, gasoline-range hydrocarbons, CO2, C12, Sulphur and nitrogen compounds, aromatics, and many others. Silica Gel is widely used in industries where a high capacity desiccant or selective adsorbent is required.

Molecular Sieve

Molecular sieves are synthetic zeolite materials engineered with pores of precise and uniform structure and size. This allows them to preferentially adsorb gases and liquids based on molecular size and polarity. There are four main types of molecular sieves: 3A, 4A, 5A, and 13X.

A molecular sieve works by adsorbing gas or liquid molecules that are smaller than the effective diameter of its pores, while excluding those molecules that are larger than the openings. Molecular sieve is commonly used in the separation of ethanol and water.

Activated Alumina Balls

Activated alumina is a porous, solid form of aluminum oxide. As a desiccant, activated alumina can be used to dry compressed air and other gas and liquid streams. It is used to purify gas streams by the selective adsorption of specific molecules. Activated alumina also has water filtration and catalyst applications. It is commonly used in the desulfurizing process for natural gas. Filters with activated alumina can be reused over and over again as it can be regenerated by heating it to any temperature between 350° & 600°F (177° to 316°C)

Molecular Sieve Desiccants in the Chemical Process Industry
Molecular Sieve Desiccants in the Chemical Process Industry
26, Feb 2020

Molecular sieve desiccants are zeolite material with pores of uniform sizes. They efficiently adsorb gases and liquids based on their molecular size and polarity. Being a potential adsorbent for different liquids and gases, molecular sieve desiccants find their application in the steel production process, drying the inner space of the insulated glass window, filtration of oxygen in breathing apparatuses and air conditioning filter cores in our cars. It is used as a cost-effective and safe alternative in various applications in the chemical process industry. Based on the pore size, molecular sieve desiccants are mainly differentiated into four types: 3A, 4A, 5A, and 13X. The 3A molecular sieve desiccants find major application in petroleum and chemical industries for refining oil, polymerization, and chemical gas-liquid depth drying. The 3A and 4A molecular sieves can adsorb air contaminants, water or carbon dioxide powerfully. Due to the high performance and renewability of these desiccants, the lithium hydrogen canisters have been replaced by molecular sieve for carbon dioxide removal from the spacecraft cabin atmosphere.

As mentioned above molecular sieves are used in various sectors of industries and one of them is molecular sieve oxygen concentrators, which is used primarily in pharmaceutical production, water treatment, and glass manufacturing. Oxygen concentrators use these molecular sieves that work on the principle of rapid pressure swing adsorption of atmospheric nitrogen onto zeolite minerals, thus removing the nitrogen gas, leaving oxygen the major gas remaining.

Being highly porous with a pore diameter of 10A°, the 13x molecular sieve beads and pellets are used in adsorbing and drying water and moisture from different gases such as H2S, H2, CO2, O2, NH3, etc. It is used in general gas drying in air compressor units.  It also acts as a catalyst carrier. Due to their lower absolute retention, 13x types are used in the petroleum industry for the PONA analysis or the separation of naphthenes from paraffins, olefins, naphthenes and aromatics. It also is used in sweetening natural gases and liquid hydrocarbon streams by removing H2S and Mercaptans.

Molecular sieves for the dehydration of ethanol
Molecular sieves for the dehydration of ethanol
26, Feb 2020

Molecular sieve desiccants are effective adsorbents for gases and liquids. Molecular sieves can be considered as a filter used to separate molecules from each other.  The type 3a molecular sieve is a mesh-like substance which does not permit molecules of diameter larger than 3A to enter. They have higher efficiency and longer lifetime compared to other molecular sieves.

The molecular sieve 3A plays an effective role in the ethanol dehydration process. Due to the azeotropic property of ethanol during normal distillation, ethanol concentration is restricted to around 95%. Molecular sieve 3A is employed to filter out the water molecules, which have a diameter of approximately 2.8A, from the ethanol molecules, with a diameter larger than 3A (approx. 4.4A) and thus produce pure dry ethanol. The foundation for this process is the concept of adsorption of water molecules from the ethanol-water mixture.

As stated above, the Ethanol dehydration process can be simplified by the use of molecular sieve 3A beads. The ethanol-water mixture is allowed to pass through a bed of 3A sieve beads under high pressure, thus activating the molecular sieves. By activating molecular sieves, the water molecules from the mixture get adsorbed and the dry ethanol molecules shall pass the sieve bed. These ethanol molecules, which are anhydrous, will be condensed outside the 3A sieve bed and can be collected separately. This is an exothermic process and the heat emitted during the adsorption can be used to regenerate the 3A sieve beads, which allows this dehydration process to consume less energy compared to other techniques.

The high regeneration ability of the molecular 3A sieves allows the reuse of the same. The sieve beds grow saturated as more water molecules get adsorbed. Water is removed and thus the sieves are purged, by applying vacuum. Hence the 3A sieves undergo a sequence of adsorption and desorption during this process.

Molecular sieves 3A have faster adsorption speed and so the entire process of ethanol dehydration, is more efficient. The use of molecular sieves 3A beads is more accurate when combined along with the conventional distillation. The concentration of ethanol is increased to around 99% (from 95%) when both the processes are combined. As the 3A sieve beads are pollution resistance and can be stored at room temperature, the process is more environment-friendly and economical too.

How can we use Molecular Sieves in Insulated Glass?
How can we use Molecular Sieves in Insulated Glass?
26, Feb 2020

Molecular sieves are used in sealed insulating glass units to prevent fogging. Fogging on inner glass surfaces by condensation of water and solvent vapors is common inside sealed dual pane windows. Window fogging arises when the vapors trapped between the two panes of the insulating glass unit condense on the glass surface. This is due to the lower temperature of the glass surface than the dew point of the air between the two panes.

To prevent fogging the moisture vapor concentration inside the dual-pane window must be controlled. Using this desiccant molecular sieves for insulated glass can absorb moisture more than all commercially available adsorbents and sometimes they also can remove solvent vapors. When moisture or solvent vapors are absorbed by the molecular sieves, the moisture vapor concentration in the air space is reduced and the moisture dew point of the airdrops to a lower value and no condensation can occur until the glass temperature goes below that.

We provide the best molecular sieves in the adsorption process. The sieves grant protection against moisture and water. They find use in many industries such as oil & gas, petrochemicals, sugar, and air industries. The sieves are used for many purposes including water removal, moisture removal, oxygen removal, natural gas drying, industrial gas drying, and natural gas dehydration. They are available in A and X type crystalline structure and in beads & pellets. The product type includes molecular sieve 5a, 4a, 3a &13x.

Mercaptan removal from LPG by using molecular sieve 13X
Mercaptan removal from LPG by using molecular sieve 13X
26, Feb 2020

Liquified Petroleum Gas (LPG) is a very popular energy source. This portable, clean and efficient source of energy is a flammable mixture of hydrocarbon gases. In its initial form, it contains impurities. Molecular sieves are used to remove these impurities from LPG so that it is safe and eco-friendly. In this article, this process is discussed in detail.

Mercaptans

Mercaptans are defined, as organic components of hydrocarbons with sulphur. These compounds are considered as impurities when present in large quantities. They have a stringent smell and are corrosive in nature. Mercaptan is the by-product present in natural gases. These impurities must be removed or reduced in quantity, for better performance and longer life of natural gases, LPG and other liquid hydrocarbons. Unfortunately, the mercaptans cannot be removed from LPG by normal distillation.

Molecular sieves for mercaptan removal

The molecular sieve 13X pellets are found to be the most effective method in removing mercaptans from LPG. Molecular sieves are used to separate molecules of different sizes, within a chemical compound. The type X crystalline foam known as molecular sieve type 13X is sodium-based and has a pore diameter of 10A. Thus, molecules of diameter less than 10A will be trapped within the molecular sieve type 13X desiccants.

The process of mercaptan removal from LPG using molecular sieve beds is very simple. The current of LPG to be processed is allowed to pass through a bed of molecular sieve type 13X pellets. As the gas current passes the sieve bed, the mercaptans present in big volumes from the LPG will be adsorbed by molecular sieve beads. The processed LPG is now free from the corrosive components. This adsorption process happens at ambient temperature. But as a huge amount of mercaptans are adsorbed, the molecular sieve beds may become saturated. Allowing a purge gas to pass through these molecular sieve beds will regenerate the sieve bed. This reactivation process is set at an elevated temperature ranging from 200 °C and 325 °C. There can be an arrangement of two sieve beds, which can conduct the adsorption and desorption processes in parallel, thus ensuring a continuous and more efficient process compared to the split process.

However, a very little quantity of one such mercaptan is allowed along with LPG, to identify any leaks, thus avoiding any kind of accidents. Higher regeneration, improved efficiency, and cost-effectiveness of Molecular sieve type 13X are its highlights.

Genuine Purification of Natural Gas with Molecular Sieve Adsorbents
Genuine Purification of Natural Gas with Molecular Sieve Adsorbents
05, Dec 2019

When some sort of chemical separation process or any purification process is going on, it is important to separate the similar-looking molecules with almost similar polarity. The purification doesn’t complete until the solution is free from these impurities. Under this circumstance, you need to use such substances that have the quality to absorb those elements that are actually causing the impurity. Molecular Sieve would be the perfect desiccant for such purposes.

The sieve desiccants are actually crystalline aluminosilicate which possesses the powerful ability to act as a gas and liquid adsorbent. The sieve has a three-dimensional structure and this fact greatly depends on the silicon oxide and aluminum oxide polyhedral. Both these substances are able to produce great adsorbents and when you make a perfect blend of these two ingredients, the produced substance is sure to have some excellent quality of absorbing the impurities from natural gases. Thus, these substances have massive uses in various chemical refining processes.

The effectiveness of Molecular Sieve Adsorbents is really excellent. These are actually best for those products that are used vastly in natural gas refining, petrochemical, and air drying industries. The performance of these adsorbents to separate the impurities is based on the molecular size. This adsorbent has the quality to absorb even the smallest size of molecules. The molecular sieves are available in different sizes and shapes and which includes balls, pellets, and powder. Among the different types of these molecular sieves, 3A, 4A, 5A, and 13X are widely used for a number of purposes. The effectiveness of these molecular sieves includes drying and cleaning technical gases.

The 3A molecular sieve is generally used to desiccate several hydrocarbons and non-hydrocarbon gas and liquids. Apart from that, these molecular sieve adsorbent packets are also used to dehydrate alcohol and solvents. The application of 4A molecules is quite similar to that of 3A molecules except, these sieves are also used to purify the electronic components as well. The application of 5A molecules is to separate the chain of hydrocarbons in order to dry the natural gas and most importantly, to produce a high level of pure hydrogen. It is basically used for commercial purposes of refining air, petroleum and gas for various industrial purposes.

The pellets and beads of Zeolite 5A are also used to absorb the oxygen. More so, in petrochemical industries, it is used to separate the nitrogen from the air. The 13X molecular sieves are used for the dehydration of the natural gas, LPG, and other petrochemical liquids.

There has been a widespread utilization of the molecular sieve technology for the removal of impurities and water from natural gas. Hence, there is an imminent need for a better understanding of the process and the operation of this molecular sieve technology.

Molecular Sieves as a Drying Agent
Molecular Sieves as a Drying Agent
05, Dec 2019

Molecular sieves generally serve the purpose of blocking large molecules from interacting by preventing them from entering a compound. On the other hand, they permit the entry of smaller user-friendly molecules. Most of the molecular sieves are used as desiccants.

The size of the molecules that are restricted and the ones that are permitted are measured in angstroms or nanometers. The general size of the molecules varies between 2 nm (nanometers) and 20 A (angstroms).

The Types of Molecular Sieves Used as Drying Agents

Molecular sieves that are used as drying agents are a combination of silica and aluminum tetrahedral. In order to be used as a drying agent, the water content has to be removed by heating the relevant substances to form equal cavities that can suitably absorb hydrated molecules of a certain size.
A mesh is used for this purpose and its dimensions will depend on the material that is to be dried. Generally, a 4-8 size sieve is used for the drying of gases, while a mesh size of 8-12 is mostly used for liquids. For powders, the 3A, 4A, 5A, and the 13x types of sieves can be used, depending on the exact composition of the powders in question.

Uses of the Molecular Drying Sieves

Molecular sieves as a drying agent have been known to be very effective in many synthetic organic procedures. Many products can be prevented from the condensation process that can severely damage their composition or the required properties. This is precisely where the molecular drying sieves play a vital role.
Most of these drying agents can remove the harmful effects of water or moisture, including alcohols that can include methanol and ethanol. Importantly, they can also prevent the formation of unwanted substances that can result in a byproduct of water or moisture.

The Importance of Solvent Drying

In the chemical or pharmaceutical industries, it is critical that only the required amount of moisture or water is present to produce the ideal composition of drugs. It is important that the process of drying of solvents is employed before the material is packed or sealed as the case may be.

Every molecule of a substance or a compound has its own unique structure and molecular size and their critical diameters. It is essential that these are kept in mind when dealing with them, especially for drying solutions.

Molecular Sieve 4A to keep your Products Moisture Free
Molecular Sieve 4A to keep your Products Moisture Free
03, Dec 2019

We all know the importance of keeping moisture out of certain foods and pharmaceuticals. One of the most effective methods of doing so is with the use of molecular sieves. There are also several liquids and gases that interfere with their composition when they come in contact with them.

The Importance of Molecular Sieve Desiccants

Molecular sieve desiccants have a much more powerful action when it comes to keeping unwanted liquids and gases when they are packed. The other well-known desiccants are comprised of either alumina or silica gel, but they are no match when compared to the potential that molecular sieves 4A have. They have one of the most effective dryings and absorbing properties known in the industry.

Molecular sieves are especially famous for their water purifying properties. Being very small in size, they have huge absorbing qualities. When water passes through them, its molecules get caught in the tiny pores and allow only clean and pure water to pass through, absorbing all the impurities. This is also the case with many other liquids and gases where high purity is essential.

Molecular sieves come in various sizes and specifications; each one of them is used for a particular purpose. They can be classified as 3A, 4A, 5A and 13x categories. Each one of them has a special role to play and can be used to perform various drying, purifying or absorbing applications.
 
The Special Features of Molecular Sieves

One of the most important features of molecular sieves is that they have the special ability to absorb about 22% of their original weight of gases and liquids. Using the adsorption process, molecular sieves are one of the cheapest and most convenient forms of keeping moisture and toxic gases out of many chemical processes, or during the final packaging stages.
 
The desiccant packets made from molecular sieves offer maximum protection from moisture and are very versatile in their applications. They also offer the best value for money for this purpose. One of the important factors is that they offer an atmosphere for products that require a very low RH level (Relative Humidity). They are especially suited where very high temperatures are involved. They are also very easy to use, as they are packed very conveniently in nontoxic or reactive packing materials like polyester or polyethylene bags. Tyvek or cotton bags are also used to suit the end process.

Use Molecular Sieve for Ethanol Drying
Use Molecular Sieve for Ethanol Drying
03, Dec 2019

Ethanol can be produced as a petrochemical by the hydration of ethylene or naturally by fermenting sugars with yeast. Industrial grade ethanol is often produced by the hydration of ethylene in the petrochemical industry. Ethanol has several end uses, such as coatings and inks for food and paper packaging, or emulsion resins for interior and exterior coatings.

Another important use is as a solvent for the synthesis of drugs, sterilizing products, etc. Today, many European countries are also using a 10-15% blend of anhydrous ethanol in petroleum. Thus, the importance of dehydration or drying out of ethanol to completely remove any presence of moisture increases significantly.

Molecular Sieve Dehydration and its Advantages

 

The molecular sieve dehydration technology utilizes the adsorption phenomenon, and this is used to produce anhydrous ethanol. The technology was first used in ethanol drying in the early eighties and has since gained significant popularity. These Molecular Sieves for Ethanol drying are made of popular materials called zeolites (chemically known as aluminosilicates as well). The industrial process essentially involved passing the vapor form of ethanol through a column of the molecular sieve, which separates any water present in the vapor form from the ethanol by trapping its molecules onto its surface while allowing molecules of ethanol to pass through. Two different subzones of operation are provided within a master transfer zone so that the two liquids part ways without any further interaction. Thus, the ‘drying out’ of ethanol is achieved.

Ethanol drying with the help of molecular sieve technology has become the most attractive option for industries due to some very compelling reasons. By reducing the energy requirements in comparison to other methods like azeotropic distillation, extractive distillation or membrane separation, the operating cost has been significantly reduced. This process also does not use any other chemical, hence eliminating the chance of contaminating ethanol with any other substance completely. The cost of the usage of such chemicals is also thus automatically eliminated altogether. This in turn also translates into higher alcohol recovery from the process, thus leading to greater revenue for the industry.

Ethanol produced from the hydration of ethylene by the petrochemical industry has several crucial industrial and commercial uses. This stems from its solvent properties, and hence the purity of ethanol is critical, for which it is often dried. Molecular sieves for ethanol drying are gaining popularity across the industry. This is so because Molecular Sieve Technology offers cost advantages and higher alcohol recovery rates.

Molecular Sieves – A Better Understanding

A lot has been written about molecular sieves and their role in keeping moisture away from packed items and industrial operations. At both these places and more, molecular sieves work around-the-clock to remove excess vapor molecules from the surroundings so that the packed items are not affected by water vapor. Molecular Sieve desiccants are available in the market in three forms- bead, balls and granular. All these forms of molecular sieve have uniform-sized pores, which allow the passage of only same-sized molecules (water vapor) and stop impurities from passing through. There are two major benefits of using molecular sieves as a desiccant. One, as mentioned above, the uniform-sized pores and second, the large surface area. While the same-sized pores attract the molecules, the big surface area ensures that more moisture molecules are absorbed over more domains.

Molecular Sieves- Their Structure, Composition

Now let us take a closer look at the structure and composition of molecular sieves. The pore size of Molecular Sieves is usually measured in angstroms. Depending on the pore size, molecular sieves are graded into various categories. These include molecular sieve 3A, 4A, 5A, 10A, and 13 X. All these various grades of molecular sieves have different purposes, depending on their pore size. Among molecular sieves, desiccants having a pore size of fewer than 2 nanometres or 20 Angstrom are known as microporous materials. Macroporous materials are those molecular sieves having a pore diameter of more than 50 nm. This is equal to 500 Angstrom.

Molecular Sieves have another category as well- mesoporous. This includes sieves having a pore diameter between 2-50 nanometres. Silicon dioxide is one of the molecular sieves coming under this category. Examples of microporous materials are zeolites, active carbon, clay, and porous glass. Macroporous materials include mesoporous silica having pore size between 200 and 1000 Angstrom.

Uses of Molecular Sieves

Molecular Sieves have many applications. The major one being in the storage and packaging industry for the removal of moisture from the surroundings so that the packed items are not affected by the presence of vapor molecules. Another field where Molecular Sieves are widely used in the petroleum industry. Here the molecular sieve is used to dry gas streams. The presence of moisture in gas streams can lead to ice formation and corrosion so Angstrom molecular sieve is used to maintain proper moisture levels in the gas streams. As molecular sieves are known to the better drying agents, it is highly recommended to buy high-quality molecular sieve products from suppliers like Sorbead India.

                                                Molecular sieve for solvent drying

Molecular sieve finds use in the laboratory for chromatography purposes like drying of solvents. Molecular sieves are used for a wide range of catalytic applications. They form the stationary phase of the chromatography process, which absorbs the different components of any given mixture. The chromatography process is used to catalyze isomerization, alkylation, and epoxidation. In industries, it is used for processes like hydrocracking and fluid catalytic cracking. This is one of the main reasons why Molecular Sieve exporters cater to high demand from other countries.

Ever since the existence of refrigeration and HVAC systems, we have often come across a term known as the refrigerant. Have you ever wondered what exactly a refrigerant is? For those who don’t know about it, here is the bookish definition of the term refrigerant. It is basically a particular substance or just a mixture of substances that are formed in the fluid or gaseous forms. The refrigerant has its primary use in the heating pumps and the refrigeration cycles. Most of these cycles see the transformation of Refrigerants from liquid to gas. Some of the notable examples of refrigerants that we could find would be fluorocarbons, sulfur dioxide, ammonia and so much more. This post is dedicated to discussing some of the applications of refrigerants or freezers, the molecular sieve filter drier that is used in the refrigeration systems and so much more. You will also get to learn a lot about the filter drier installation that helps in the extraction of moisture from the refrigerants.

Commercial and Personal Uses of Freezer and Refrigerants

The refrigerants like carbon dioxide, ammonia, and the other non-halogenated portions of hydrocarbons are not responsible for the depletion of the ozone layers. These refrigerants also don’t have any or just a little bit of potential in harming the global climate as well. Hence these freezers or refrigerants are mostly used in the proper air conditioning systems that are provided in the buildings, leisure, and sports facilities. Apart from that, these freezers also have a very important use in the pharmaceutical industries, automotive organizations and most importantly the food industry as well. The emissions that come out from the air conditioning systems provided in the automobile industries can, however, be considered as a particular growing concern only because they have a significant impact on the change of the climate. There have been some changes made for that as the unions have successfully managed to phase out most of the refrigerants that have the potential for global warming in any way. Using the CO2 refrigerants is a very beneficial alternative that people can use since it is pretty much non-flammable and hence will not be able to harm the ozone layers. So, these refrigerants might just have better use in the cars, hot water pumps, commercial refrigeration, residential cooling, and the vending machines as well.

Importance of Freezer and Refrigerant in Daily Life

As we all know, there are many different uses of having refrigerants and freezers in the daily life of the people. Most of these refrigerants surely have a lot of commercial uses, but they can also be used in the day-to-day lives of the people. For example, freezers are a very important part of the refrigeration cycles. So, this means that they are a great addition to the refrigerators in the homes of people. These refrigerants help in keeping the food in the home quite fresh and healthy to eat at any time. Most of the time, having fresh fruits and vegetables is really important. The refrigerants help in controlling the temperature of the refrigerator and hence help in the cooling of the foods. With the low temperature, there is no possibility for the growth of bacteria that plays a very important role in the degradation of the food. Another one of the most important uses of having refrigerants for our daily lives is that they help a lot in enhancing the air-conditioning system of the houses. There is no doubt about the fact that air conditioning is very important, not just for the people but the electronic devices as well. Keeping the devices cool and at a very low temperature helps in the extension of their lives. Most of the electronic devices also come with a separate air conditioning system that uses the refrigerants in order to maintain a cool temperature. Apart from that, the HVAC systems in the homes of people also use the refrigerants in order to make sure that the air that comes out is always cool and refreshing.

Freezer & Refrigerants Major Malfunctions

Most of the chillers and the air-conditioning systems suffer from the problems of reduced efficiency because the freezers and refrigerants get contaminated with excess water, oil, acid, and air as well. if these contaminants are available on the refrigerants in more quantities, then it can lead to several issues such as failure of the systems.

Excess Oil

Oil is one of the components that can provide some harmful effects to the working of the cooling systems in the devices. However, not much has actually been done in order to locate or remove the oil that is present in the cooling system. There are several reasons behind that. Oil might just decrease the efficiency of the system but it necessarily doesn’t do any harm other than that. Oil can be considered a lesser harmful contaminant when compared to others such as moisture and acid. Acid Formation When we talk about the harmful contaminants that actually lead to the destruction of the systems, then acids are the first things that come to mind. The acid development in these freezers or refrigerants on the heat pumps, refrigerators, air conditioners, and other devices can be responsible for the life-shortening of the refrigerant. There are many possible reasons for the formation of acids. It could be due to the different chemical reactions that happen in between the different materials and components. Most of the time, the impurities inside the refrigerants can also be responsible for the creation of acids. Apart from that, an increase in the temperature also accelerates the formation of acids in the refrigerants Too Much Moisture The presence of moisture in these freezers and refrigerants is certainly one very common problem that can take place. It will also be very expensive to treat as well.

The refrigerant that has moisture in it will not just affect the efficiency of the refrigeration system. It will also be responsible for some serious long-term damage to the system in many different ways. If the moisture is not detected and removed with the help of filter drier in the refrigeration system, then it can result in several expensed related to the repair and downtime of the system as well. Moisture can lead to the formation of ice in the valves which causes further blockage. Also, it can make a mixture with the oils present inside the system compressor in order to form harmful acids and then attack all the motor windings which will further lead to burnout. Moisture also has an effect on the bearings as it makes them seize. Apart from that, it can also block the flow of the oils as well. So, these are some of the dangerous malfunctions that can occur in the freezers and the refrigerants. It is important to use a refrigerator filter drier to solve these problems. We will get to that in a while.

How Is Acid Formed In Refrigerants Due To Moisture Issues?

When it comes to the effects of moisture, acid formation is one of the most common effects that can cause harm to the refrigerants and ultimately the cooling system as well. The moisture accumulates in the refrigerants in different degrees. With the increase of moisture, it starts to mix up with the other materials present in the refrigerant. As a result, the mixture is then open to react with anything. Most of the time, it happens that the mixture of moisture and the refrigerant reacts along with the different lubricating oils and various other materials that are present in the system. This leads to the formation of strong compounds that have a corrosive nature. We all know that the chemical reactions that happen in the system often lead to the formation of acids. These acids that are formed can actually damage the valves, bearing journals, seals, and other important parts of the cooling system. Sometimes, the acids present can also cause the compressor to burn completely and thus degrading the cooling efficiency of the system. With the help of the molecular sieve desiccants present in the filter driers that are used for the extraction of moisture, these moisture issues can be prevented. Let us get to know a little bit more about it.

Troubleshooting the Acid Formation Due to Moisture Issues

We all surely know by now that the major reason for the formation of acids in the refrigerants would have to be the moisture that is present in these components. However, there is a solution to that problem as well. The filter driers with molecular sieve RH3 and molecular sieve RH9 are some of the options to go for. One of the primary functions of the filter drier is to make sure that the moisture is completely removed from the refrigerant systems. There are many different sources from which moisture will be able to enter the system. Improper evacuation due to trapped air and leaks in the systems are some of the reasons. The moisture that is present in the refrigerant system will be responsible for the metallic corrosion of the components. Apart from that, the moisture in the system also has the potential to form several organic acids which in turn will affect the operation of the components. In order to make sure that the formation of the acids is minimized, it is imperative to stop or pause the formation of moisture in the refrigerant. This can easily be done with the help of a filter drier. The filter drier uses the molecular sieve in order to make sure that the moisture is taken out from the refrigerant. We will get to know about that in a while.

Selecting the Desiccant for the Filter Drier: Molecular Sieve Introduction

For the removal of the components that might harm the refrigerant, the filter driers are used by every single industry. However, without the use of the proper desiccant, the filter driers will not be of any use. Here we are going to provide you with an introduction to a filter drier desiccant which is known as the molecular sieve. When you are selecting the perfect desiccant for the filter-drier, there are many different factors that are supposed to be considered. The water-absorbing capacity, the lubricant and refrigerant compatibility and so much more factors need to have special importance when selecting the proper desiccant for the filter drier. If the proper desiccant is not selected, then you might have to go for a refrigerator filter drier replacement. Let us start with the water capacity, people. The water capacity can be defined as the ability of the desiccant to hold the water. We all know that the function of the filter drier is to make sure that the levels of moisture in the refrigerants always remain low. So, the more water capacity a desiccant has, the better it will be for the refrigerant. The molecular sieve helps a lot when it comes to retaining the amount of water. These sieves have got the highest capacity for water absorption and hence can be easily used for the task. The molecular sieve would absorb the moisture and help in keeping a low concentration of the refrigerant water. The strong bonds that take place between the moisture and the molecular sieve are the reasons behind that. It is by keeping the water levels in the system very low, the corrosion problems, freeze-ups, and the formation of acids can be effectively minimized.

There is the activated alumina that can be used in order to retain a little amount of all the moisture, but the retention capacity isn’t really that great as is seen in the amazing molecular sieve that we have. It is also recommended that when it comes to the molecular sieves in the filter driers, they help in water removal in the most efficient way. Apart from the water capacity, the lubricant and refrigerant compatibility also plays a very important role in the selection of a particular desiccant. The organic and inorganic acids form due to the reactions that happen in the systems. These acids have the potential to damage the entire refrigerant system. Without having a proper desiccant these acids can also enter the valves and other important areas to cause severe damage there as well. This is where the molecular sieves come to help again. The acid removing the capacity of the desiccant depends on the size of it. If you want to know all the about the molecular sieve sizes, then you can take the help of the molecular sieve size chart. The different pore sizes present in the molecular sieve help in the removal of the molecules of organic acid in the best way.

There is another factor that would decide the selection of the desiccant for the filter drier. The desiccant strength is a very important factor to consider. The desiccants that are inserted in the refrigerant filter driers need to be quite strong so that they can resist the effects of the different surges and vibrations that are caused in the system. The molecular sieve XH-7 receiver drier certainly has the strength that is required in order making sure that the changes in the systems don’t have any negative effects on them. Molecular sieve XH 7 and XH 3 are some of the molecular sieves that are most commonly used in the refrigerant systems due to their moisture absorption capabilities. These honey-comb shaped structures are very uniform in the size and help in the absorbing of the moisture molecules that are present in the refrigerants. If you select the proper filter drier along with the perfect desiccant, then absorbing the larger moisture molecules as well as the smaller molecules will be pretty easy. Another great thing about the molecular sieves is that they are entirely coated with some positive charges which are known as the cation. These cations help in attracting the molecules that are polarized, just like water. So, there is no doubt about the fact that the filter driers that have molecular sieves in them will be able to keep moisture away and thus prevent freeze-ups, acid formation, and several other issues in the refrigerant system.

Does Size Matter When it Comes to Choosing a Filter Drier

Most of the time, it happens that the differences in the size of the filter driers create confusion in the minds of the people. Now, the question that arises here is whether the filter drier size is actually that important or you need to focus on the other factors more. To be honest, the size of the filter drier is not really that big a deal when it comes to the consideration of the other factors. Although there is a direct relation between the capacity of the filter and the volume, it is also true that the type of the desiccant that is used in the filter drier also plays a very important role in the selection of the filter drier. Always going for the biggest of the filter drier might not be the option that will always provide the best of the results. Even if you do that, you need to make sure that you know how to replace filter drier so that you don’t face any problems in the future. Knowing the filter drier location is also very important in order to replace it.

Working Principles of Filter Drier with the Help of Molecular Sieves

There is no doubt about the fact that the molecular sieves are some of the best desiccants that can be used in the filter driers. That is because of the high water capacity that they have. When it comes to discussing the working principle of the filter driers with the help of molecular sieves, there are several things that come to mind. The molecular sieve that is present in the filter drier has a crystalline structure that helps in the absorption of the water that is present in the refrigerant systems. Apart from that, the molecular sieves also play a very important role in removing the organic acids which are caused due to the contamination of moisture and the other components that are present in the refrigerant systems Furthermore, these sieves are the perfect solution for the compressor burns, corrosion problems, acid formation, and a plethora of other problems that often occur in the refrigerant systems as well. That is not it as the filter driers also take the help of molecular sieve in the filtration processes as well. The molecular sieves help in removing the solder particles, scales, and various other foreign elements that can block the compressors and the valves. Thus, it can be safely concluded that these sieves play a very important role in the filtration of the refrigerants. The larger and the smaller particles are caught by the pores of the molecular sieve, thus providing a clear way for the movement of other essential materials. Knowing all about the molecular sieves and its use in the filter dries of the refrigerant systems will surely provide you with an idea about how the system works and what can be done in order to improve on the issues that crop up with the modern-day refrigeration systems. With the help of the proper desiccants such as molecular sieves, users will be able to ensure that their air conditioning and refrigeration systems stay in a proper state always. For those who want to know about the molecular sieve price, going to the best molecular sieve suppliers would be recommended.
