The demand for using molecular sieves in the natural gas industry has been increased to a great extent due to their higher adsorption ability at the most competitive price. To prevent corrosion, the formation of hydrate and freezing of gas molecules in cryogenic equipment, it is required to remove the impurities in order to supply highly pure natural gas to the processing plants. For natural gas purification/separation, different types of molecular sieves such as 3A, 4A & 5A are used depending on the pore size and molecule diameters.
These molecular sieves in the form of beads and pellets are available to adsorb water and other compounds while avoiding the formation of carbon dioxide.3A, 4A & 5A acts as a drying agent that offers highly beneficial and selective adsorption properties to obtain a purified gas. The use of these adsorbents is widely spread for the contaminant separation from natural gas. The mixture of gases or compounds with water is passed through the beads or pellets series of 3A, 4A or 5A to for the separation due to the sieving effect. These molecular sieves are used depending on the molecule diameters, bulk density, crushing strength, static water adsorption as well as water content. For natural gas purification/separation, these adsorbents play a great role in obtaining the desired industrial gas which can be used for various applications.
It can be regenerated at a certain temperature and becomes ready for reuse. An improper regeneration can reduce the quality of the product if the temperature is too low. Even the excessive temperature can also reduce life span of adsorbent or can decompose the adsorb in some circumstances. So, it is required to maintain the right temperature for the regeneration process. Get high quality and purified natural gas with the help of right and effective desiccant.
