DESCRIPTION

Silica Gel Desiccant _ Variable-Pressure Adsorption Silica Gel

SERVICE ON...
Detail

Properties

Color: transparent or translucent; bead-like. Chemical molecular formula: SiO2, . nH2O; Chemically stable, Nontoxic, tasteless, Similar to fine porous silica gel. but its selective adsorptive capabilty is higher than fine porous silica gel.


Application

Pressure swing ansorption silica gel is a kind of new high technology used for gas separation and purification. It's mainly used for the recovery, separtation and purification of carbon dioxide. lt is used for preparation of carbon dioxide in synthetic ammonia industry, food & beverage processing industry, etc. It may also be used for drying, moisture absorption as well as dewatering of organic products.
