4A Molecular Sieve Adsorbent is a clay-bound sodium form of Type A molecular sieve. 4A molecular sieve will adsorb molecules with critical diameters up to 4 angstroms. It adsorbs water and ethanol, but not larger molecules like propane.

APPLICATIONS:

4A molecular sieve is recommended for deep drying of gases and liquids, such as natural gas alkane, air, carbon dioxide etc. 4A molecular sieve is used for static drying for electronic component and hygroscopic substance and dehydration of coating and polyester.

TOP also supply specialty 4A products: 4A-DG for natural gas and saturated hydrocarbon dehydration; 4A-LNG for natural gas purification for cryogenic storage.
 

TOP's molecular sieve adsorbents have high adsorption selectivity and capacity. The high efficiency, low consumption and strong reliability of TOP's MS enables the customers to lower the volume of filling adsorbents under same technology requirement, and to extend the adsorbing cycle and reduce the investment, operation and lower the energy consumption.
