Stroke of the piston compressor valve gate for small air separation unit

Stroke of the piston compressor valve gate for small air separation unit
Mar 07, 2022
Author: DEAR AST

The stroke of the valve plate of the piston compressor valve of the small air separation unit should be reasonably selected according to the speed and pressure of the compressor and should not be too large or too small. If the valve stroke is too large, the valve blade may not open fully and may also close with a hysteresis due to the inertia of the moving parts. At the same time, if the stroke is too large, it will increase the speed of the valve blade when opening and closing, and the impact on the restrictor and valve seat will increase. If the stroke of the valve blade is too small, it will increase the resistance loss, reduce the flow capacity and affect thesmall air separation unit productivity and efficiency of the compressor.

Dear Institute of Air Separation Design and Research has a number of patented technologies in the field of air separation energy saving. As an important user of industrial gases, oxygen, nitrogen and argon have become indispensable energy media in steel production, and the small air separation unit and large air separation unit are the "heart" of gas production.

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.
