Molecular Sieve for Carbon Dioxide Removal

Molecular sieves act as an effective adsorbent for various liquids and gases. It is also considered as the alternative method of carbon dioxide removal due to its high performance, safe and cost-effective properties. 3A and 4A are the molecular sieves adsorber’s with the ability to adsorb critical air contaminants, water or carbon dioxide powerfully. These drying agents are available in the form of beads and pellets that work efficiently in natural gas adsorption and various other purification processes. Their adsorption process depends on the molecular diameter as well as the polarity of adsorbate.

Carbon Dioxide Removal

3A is the potassium-based molecules with a pore size of 3 angstroms whereas 4A is the sodium-based molecules with the pore size of 4 angstroms. These adsorbents of Type A crystalline structure have the capability to adsorb carbon dioxide from the dehydration of air or natural gas.4A desiccant has more tendency and power to adsorb carbon dioxide as compared to 3A desiccant. The industrial gases and several other products play an important role in glass, steel and medical applications where oxygen or natural gas needs to be dehydrated and purified using the activated molecular sieve adsorbents. 4A also helps in drying and removing the CO2 from steam cracked gas, LPG and various atmospheric gases.

Both types of molecular sieves can be regenerated and reused by removing the adsorbed moisture, gases, and other materials. It means that you can regenerate the particular sieve by simply removing the CO2 at some specific temperature. These sieves can then work perfectly for hydrating, separating and purifying the industrial natural gas liquids used in different applications and industries. 3A and 4A adsorbents in beads and pellets form are highly recommended for adsorbing carbon dioxide using the valuable adsorption process.
