Column configuration and method for argon production |
摘要 |
A system for achieving a low level of nitrogen in a lower pressure column in the feed to the argon column in a cryogenic air separation system by use of two beds of structured packing of about equal height in the lower pressure column, with mixing and redistribution of liquid between them. The packed beds are located between the feed from the argon column top condenser and the point where the argon column feed is withdrawn. <IMAGE> |
