It is used in drying process of industrial gas and gas purification of air separation unit; dehydration and desulfurization of natural gas, liquefied petroleum gas, liquid paraffin (propane, butane) (removal of H2S and mercaptan), drying and purification of ammonia synthesis gas.
Molecular Sieve 4A is used as a desiccant in an array of industrial applications. For instrumental air drying (for ensuring a dew point of -60/-800C. Dehydration of drugs, electric components, and unpreserved chemicals when packed Removal of moisture in plastics and paints; Drying of Refrigerants.
Molecular sieves, 13X/10A may be used for commercial gas drying, air plant-feed purification (simultaneous water and carbon dioxide removal) and liquid hydrocarbon/natural gas sweetening (hydrogen sulfide and mercaptan removal).
