Regeneration

1.                Moisture removal: The Products can be reactivated by thermal            sewing. The temperature of the inlet gas through the molecular           sieve bed should be 200-350≧ and the pressure 0.3-0.5kg/cm2 while         The temperature of the outlet gas from the bed should be 150-180

2.                Organic gas removal: First the vapour is used to remove the       organic substance, then the moisture is displaced.

Storage  Prevention against moisture.
