Double column distillation in air separation

Double column distillation in air separation
The operation is the same as the non-conventional external compression process and is relatively simple. The nitrogen compressor has an inlet pressure of 5kPa and the outlet pressure is configured according to the user's pressure requirements. Air positive flow expansion is used and the liquid product can be increased appropriately.

At present, the crude argon condensing column process is used in the double column process. The rigid connection between the main stream process and the argon extraction process is artistic both in design and operation. If there is a slight difference, it will be a thousand miles away. Secondly, to achieve the oxygen content index, the number of theoretical plates is 200, which has reached the limit of the project. ...
