Regeneration
1. 3A molecular sieve 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.
2. To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerate molecular sieve can give moisture dew points below -100°C.
3. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.
Storage
The molecular sieve should be stored in dry condition with air-proof package, cannot be exposed in the open air, and prevented against water, acids and alkalis.
