Isothermal throttling refrigeration in large air separation plant

Isothermal throttling refrigeration in large air separation plant

Author: DEAR AST

Air can be reduced in temperature by throttling in large air separation plant, isothermal throttling is an isoenthalpy process and does not produce cooling. If the gas is to be cooled by isothermal throttling, it is compressed by isothermal compression and expanded by throttling. The enthalpy of the gas decreases during isothermal compression and the work of the compressor and the enthalpy drop of the gas are transferred to the environment together as heat. The isothermal compression gives the gas the ability to cool down and the throttling expansion makes this ability manifest.

When the amount of processing air is reduced, the rising steam and reflux liquid in the upper column will be reduced, but the reflux ratio will not change. Therefore, the reduction of processing air in a small range will not affect the purity of oxygen and nitrogen, and the reduction of processing air volume will help to reduce the pressure of the upper and lower columns. However, according to the material balance, the production of oxygen and nitrogen will naturally decrease when the amount of processing air is reduced. If the amount of processing air is too small, there will be leakage on the tray. If the heat and mass exchange of the leaked liquid is not sufficient, the purity of oxygen and nitrogen will be greatly affected, and even the normal production can not be realized. Therefore, the minimum allowable load of distillation column is generally specified.
