Process and installation for the production of argon by cryogenic distillation |
摘要 |
An installation for the production of argon comprising a double column (1, 3) and an argon purification column (5). An auxiliary column (9) serves to effect the nitrogen-oxygen separation, and is supplied by a stream from the low pressure column (3). Therefore, nitrogen does not contaminate the stream sent to the argon purification column (5).
