Use

Variable-pressure adsorption is a kind of new high-technology used for gas seperation and purifying. Mainly used for the recovery, seperation and purifying of carbon dioxide gas. It is used for preparation of carbon dioxide in synthetic ammnia industry, food and beverage processing industry, etc. It may also be used for drying, moisture adsorption as well as dewatering of organic products.
