Air separation unit not only has the distillation and separation process of air under the condition of deep cooling, but also the process of keeping the air separation unit in the deep cold state and making the cryogenic liquid products. Therefore, in addition to distillation process, air separation unit has a very important refrigeration process.   Unlike the general refrigeration process of heat pump, the refrigeration prin...

The liquid oxygen from the main condensing evaporator is compressed by the internal compressed oxygen pump, evaporated and reheated into the main heat exchanger and then out of the cold box as oxygen product. The low-pressure nitrogen is pumped out from the top of the low-pressure tower, and its cooling capacity is transferred to the reflux liquid in the subcooler, which is sent out of the cold box through the main heat exchanger, partially compressed by the first stage of the nitrogen make-up c...
