The air separation expander is one of the heart parts of the air separation plant. The cold capacity is obtained by the medium entropy expansion of the gas in the expander to supplement the cold loss of the system. The main working object of air separation expander is gas. When the gas has pressure and temperature, it has energy consumption. The main function of the air separation expander is to use the internal energy of the gas through the expander to reduce and output work. Due to the reduction of internal energy and external output work, the pressure and temperature of gas are greatly reduced, so as to achieve the purpose of refrigeration and cooling.
