Standardization of cryogenic air separation equipment

What is the purpose of pressure testing for the completion of the light tower in the air separation equipment?

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...
