Operation method of improving oxygen extraction rate in small air separation

In the operation, the methods to improve the oxygen extraction rate are as follows: when the potential of upper column distillation is allowed, all the expanded air is sent to the upper column as far as possible; When the oxygen purity reaches the standard or meets the needs of users, increase the amount of oxygen taken out; Try to improve the average nitrogen purity or reduce the oxygen content of sewage nitrogen; As far as possible ...

Can 4-5% argon fraction be used as distillation feedstock for small air separation argon extraction units?

The argon fraction containing 10% argon is used as the raw material for condensing and rectifying the argon in the two column process, the crude argon rectifying column process, the open heat pump process and the new single column process. Can the argon fraction containing 4-5% argon be used as the distillation raw material for the argon extraction unit? Or more directly, the air separation column is co...
