3A molecular sieve is a multiple purpose, highly porous, high-capacity alkali metal alumina-silicate in the spherical form. It is the potassium form of the Type A crystal structure with pore diameters of approximately 3Å. The 3Å pore opening will allow moisture to be adsorbed but will exclude unsaturated hydrocarbons and highly polar alcohols such as methanol and ethanol. It has high mass transfer efficiency and durability.
- For the drying of highly polar alcohols such as ethanol and methanol
- Drying of unsaturated hydrocarbons (ethylene, propylene, butadiene)
- Static dehydration of gas, static dehydration of air-filled insulated glass units
- Natural gas drying
