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¡æ
and
the
pressure 0.3-0.5kg/cm2 while
The temperature of the outlet gas from the bed should be 150-180¡æ
2.
Organic gas removal: First the vapour is
used to remove the organic
substance, then the moisture is displaced.
Storage Prevention
against moisture.
