Typical Application 1) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien) 2) Cracked Gas Drying3) Drying of natural gas, if COS minimization is essential, or a minimum co-adsorption of hydrocarbons is required. 4) Drying of highly polar compounds, such as methanol and ethanol5) Drying of liquid alcohol

6) Static, (non-regenerative) dehydration of insulating glass units, whether air filled or gas-filled.7) Drying of refrigerants

 

RegenerationMolecular sieve Type 3A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

 

Size 3A - Zeolites are available in beads of 1-2 mm, (10x18 mesh) 2-3 mm, (8x12 mesh) , 2.5-5 mm, (4x8 mesh) and as powder, and in pellet 1.6", 3.2".

AttentionTo avoid damp and pre-adsorption of organic before running, or must to be reactivated.
