Notes:The data is obtained after liquid products are reduced gaseousness. Nm/h is the dry gas volume at 0℃ and 760mmHg.
Pressure is calculated with 0m datum mark of cold box outlet.
Process features
The air separation plant is of an internal compression process of oxygen & nitrogen, with molecular sieve purification system, middle pressure turbo-expander with booster and upper packing column, using the technology of expanded air entering lower column and full rectification argon production.
