3A molecular sieve

Molecular sieves are crystalline metal aluminosilicates having a three-dimensional interconnecting network of silica and alumina tetrahedra with uniform pore size. These pores have diameters about 3-10 angstrom, thus larger molecules exclude while smaller molecules (such as water) can be adsorbed easily. According to this property, molecular sieve technology is generally used for the simultaneous removal of water (Dehydration) and sour gas such as CO2, H2S, in addition some of light and heavy thiols from both gas and liquid feed stream. Dehydration is a crucial operation in natural gas conditioning as it reduces the potential for corrosion, hydrate formation and freezing in process equipment and transportation pipelines. 3A molecular sieve has an effective adsorbent for this purpose with pores opening of about 3 angstroms(0.3 nm)This is large enough to allow in moisture but excludes other molecules, so water content can be decreased effectively
