The Economic Benefits of Deep Cold Air Separation Technology

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...

The ratio of the actual expansion refrigeration capacity of the expander to the theoretical isentropic expansion refrigeration capacity is the efficiency of the expander. In small air separation unit operation, the efficiency of the expander is generally reduced for the following reasons: poor cooling, the outside world has more heat transfer, pay attention to keep the insulation material dry; inlet and exhaust valves are not closed, exhaust valve seat pressure sleeve top wire is too loose or in...
