5A Molecular Sieves for Air Drying

Molecular Sieve type 5A is an alkali alumino silicate; it is the sodium form of the Type A crystal structure. 5A molecular sieve has an aperture about 5 angstroms (0.5nm).It doesn't absorb any molecules larger than 5A, including propane. It absorbs water, methanol, ethanol, sulfureted hydrogen, sulfur dioxide, carbon dioxide, ethylene, propylene mainly.

Application
The strong ionic forces of the divalent calcium ion makes it an excellent adsorbent to remove water, CO2, H2S from sour natural gas streams, while minimising COS formation. Light mercaptans are also adsorbed.
It is also used for the separation of normal- and iso paraffins.
Production of high purity N2, O2, H2 and inert gases from mixed gas streams.
