Gas Separation

The main source of industrial gases is air, which separates N2, O2, CO2, Ar, Kr, Xe and other gases through the air separation rectification tower. In mass production, air is not cooled directly by adiabatic expansion, but is first compressed. After all, the work W of the expansion of air from 1 atmosphere to low pressure is limited, and low pressure will also reduce the liquefaction temperature of gas, and increase the volume of the system. It is the so-called "will take, must first with it", the air in the air separation device is first pressurized by the compressor unit, and then expanded. The compressor unit is driven by the steam turbine, where the compressor is responsible for compressing all the intake air to a few tenths of a mpa, and the supercharger further compresses part of the air to a few mpa pressure.
