Typical Chemical Formula

Na2O . Al2O3 . 2SiO2 . 4.5 H2O

(SiO2 : Al2O3 ≈2)

Typical Application

a) Drying and removing of CO2 from natural gas, LPG, air, inert and atmospheric gases, etc.
b) Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)
c) Special types are used in the air break units of buses, trucks and locomotives.
d) Packed in small bags, it may be used simply as a packaging desiccant.
