Air Plant Feed Purification

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...

Ammonia Removal from Hydrogen

Ammonia is a colorless, strongly basic gas used in explosives, cleaning solutions, fertilizer, and refrigerants.  Chemical Design, Inc. can remove ammonia from hydrogen or syngas using a high pressure temperature swing adsorption...

Anhydrous HCL Recovery

Chemical Design, Inc.’s proven technology recovers hydrogen chloride as an anhydrous liquid using adsorption and distillation.

Argon Purification (Deoxo – Drying)

Air contains 0.9% Argon. Cryogenic distillation separates the argon from nitrogen and oxygen. Argon withdrawal from the cold box contains some residual oxygen. Chemical Design, Inc. catalytically reacts the remaining oxygen with hydrogen to form water. The resulting...

Benzene Removal

Benzene is a clear, volatile liquid used as an intermediate in making plastics, resins, and other materiasl. Chemical Design, Inc.’s adsorption system can remove and recover benzene from hydrogen chloride, hydrogen, or natural gas streams.
