Molecular sieve 3 A

Regeneration:

1. Dehydration: At 200-350℃ and in pressure of 0.3~0.5kg/cm3, let a dryer gas goes through the sieve bed for 3~4hours. As the temperature in outlet at 150~180℃, let the bed cool off.

2. Removal of organic components: Replace the organic components with steam, then dehydrate
