Application:
·drying of unsaturated hydrocarbons(e.g.ethylene,butadien)
·cracked gas drying.
·drying of natural gas,if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required..
·drying of highly polar compounds,such as methanol and ethanol.
·static,(non-regenerative)dehydration of insulating glass uints,whether air filled or gas-filled.
·dehydration of refrigerant.
