Chosun Instrument Inc.

Ammonium nitrate is thermally decomposed to separate nitrous oxide and water and the machine collects & produces nitrous oxide through a refinery. In addition, using a different boiling point, the machine purifies and produces high-purity nitrous oxide. 

▶ Technical Features:

Used in diverse sectors (medical anesthetic gas, semiconductor processing, whipped cream manufacturer, etc.)

Joint technology development with Korea Research Institute of Chemical Technology

• Uses a selective gas membrane to purify nitrous oxide
• Nitrous oxide recovery and purification process from nitrous oxide containing gas mixture
