Abstract
A process for recovering argon in which a crude argon column is supplied with an argon feed gas containing a larger proportion of oxygen from a double rectifier and is cooled at its head portion with or without liquid air from a sump of the lower column of the double rectifier for producing a reflux of argon in the crude argon column. In the process, argon gas is compressed to a pressure sufficient for evaporating liquid oxygen fed from a condenser of the double rectifier, is then precooled in a heat exchanger, and thereafter liquefied by heat exchange with the liquid oxygen. Then the head portion of the crude argon column is cooled with the liquefied argon, which is then returned in a gaseous state for further compression to thereby circulate the argon gas.
