German Democratic Republic Conference on Refrigeration Engineering.

摘要

In February 1959, Soviet oxygen specialists visited the GDR (German Democratic Republic), where they attended the scientific and technical conference on refrigeration engineering organized each year by the Chamber of Technology. A total of eight reports were presented and discussed by the participants at the conference. In our opinion, the report presented by Prof. Jungrilkel (GDR) describing the production of pure argon as a by-product at nitrogen fertilizer plants is of great interest to specialists working in the field of low-temperature refrigeration engineering. This method of producing argon was used with a unit having a capacity of 3000 m3/hr of 99.5% pure argon. This unit was recently put into operation at the Leuna Chemical Plant. The argon extraction factor of this unit is approximately 0.5. In view of its reliable operation and the relatively low cost of obtaining argon in this manner, Fast German specialists believe that constructing equipment capable of extracting argon from the air is not expedient at the present time.
