Process for the production of high purity argon |
摘要 |
The present invention is a process for producing a high-purity argon stream from a feed gas containing nitrogen, oxygen and at least 85 mole % argon, Nitrogen is absorbed from the stream followed by catalytic hydrogenation to remove oxygen. The absorption column is regenerated at a preset low pressure using the nitrogen-depleted stream from the absorption unit as the purge gas.
