The main purpose of air separation equipment is to separate the oxygen, nitrogen and other components of air. In order to perform the separation efficiently, it is usually necessary to compress the air to a higher pressure. Centrifugal compressors efficiently increase the pressure of the air to provide the necessary conditions for the subsequent separation process.
At high pressures, the relative volatility (i.e. the difference in vapour pressures of the components at the same temperature) of the components in the air changes, and centrifugal compressors, by providing a high-pressure environment, enable the air separation equipment to more efficiently separate the required components such as oxygen and nitrogen. Centrifugal compressor has simple structure, stable and reliable operation. In the air separation equipment, the centrifugal compressor can run continuously for a long time, providing a stable compressed air flow for the whole system, ensuring the continuity and stability of the air separation process. Centrifugal compressors can be adapted to air compression tasks with different flow and pressure requirements. By adjusting the operating parameters of the centrifugal compressor (e.g. rotational speed, inlet guide vane opening, etc.), it is possible to flexibly meet the air compression requirements of different production demands.
Centrifugal compressor in the air separation equipment plays an important role in providing high-pressure air, improve separation efficiency, energy saving, stable and reliable operation and adaptability. It is one of the indispensable key equipments in air separation equipment.
