AIM-3A Molecular Sieve

AIM-3A Molecular Sieve is a potassium A crystal structure of alkali metal alumina-silicate with about 3 angstroms (0.3nm) pore size. It can sperate moisture from unsaturated hydrocarbons which can potentially form polymers. Specific applications are Ethylene drying , Ethanol drying; Methanol drying; Natural gas dehydration; Propylene drying; Static dehydration of air-filled insulated glass units; Static dehydration of gas Butadiene drying; Cracked gas drying etc.
