Reactivation:
1Removal of water: Hot gas at 200-350 and pressure 0.3-0.5/2 flows through the molecular sieve bed for 3-4 hours. let temperature decreases down to 110-180, cooling.
2Removal of organics: Regeneration is achieved by means of steam treatment to remove organics, and then remove water with method 1.
