Molecular Sieve Type 4A

it 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, NH3, H2S, CO2, methanol, and ethane but not larger molecules like propane.

Z4S can be applied for both liquid and gas dehydration. Such as natural gas, air, propane, LPG and other hydrocarbon dehydration.

Z4S can be regenerated for re-use by purging at elevated temperatures with regeneration gas. The degree of regeneration is dependent on the temperature and humidity of the regeneration gas.
