Air Plant Feed Purification

air prepurifier

Cryogenic distillation of air into Nitrogen and Oxygen is the most effective method for commercial production. Chemical Design, Inc.’s Air Pre-purifier removes water and carbon dioxide prior to entering the cold box to prevent freezing. In addition, trace hydrocarbons such as Acetylene are removed before their buildup can cause a safety hazard. Systems are designed using 2, 3, or 4 adsorber vessels depending on the process conditions. Our proprietary four adsorber vessel design allows for a continuous flow of regeneration gas thus eliminating a sharp peak electrical demand by recouping the heat. The electric heater can be reduced to 50% of its normal two adsorber size.
