Working principle of air separation equipment

There is an open heat pump argon extraction process.   The new single column process can only use the open heat pump argon extraction process. Taking 10000cm³ air separation as an example, the main parameters are described as follows.   1、 The quantity of argon fraction is 4200-4300cm3 / h, the content of argon is 10%, the content of nitrogen is 1%, and the rest is oxygen.   2、 The theoretical plate number of the whole column is about 100.   3、 Two heat pump dist...
