What is the function of air compressor

1. Compressed gas for refrigeration and gas separation:
The gas is liquefied after being compressed, cooled, expanded, and used for artificial refrigeration (refrigeration and air conditioning, etc.) such as ammonia or Freon air compressors. The compression pressure is mostly 8-12 kg/cm2, and this type of air compressor is usually called a “refrigerator” or “ice machine”. In addition, if the yeized gas is a mixed gas, each component can be separated separately in the separation device to obtain various gases that are qualified for lip reading. For example, pure oxygen, pure nitrogen, and pure xenon, krypton, argon, helium and other rare gases can be obtained after air liquefaction and separation of mobile air compressors.

2. Compressed gas is used for synthesis and polymerization;

In the chemical industry, gas compression to high pressure is often beneficial for synthesis and polymerization. For example, ammonia is synthesized from nitrogen and hydrogen, methanol is synthesized from hydrogen and carbon dioxide, and urea is synthesized from carbon dioxide and ammonia. In the chemical industry, for example, the pressure of high-pressure polyethylene reaches 1500-3200 kg/cm2.

3. Hydrofining of compressed gas for oil:

In the petroleum industry, hydrogen is artificially heated and pressurized to react with oil, which can crack the heavy components of hydrocarbons into light components of hydrocarbons, such as lightening of heavy oil, hydrofining of lubricating oil, etc.

4. Gas delivery:

The air compressor used to transport gas in pipelines, the water-cooled screw air compressor determines its pressure depending on the length of the pipeline. When sending remote gas, the pressure can reach 30 kg/cm2. The bottling pressure of chlorine gas is 10-15 kg/cm2, and the bottling pressure of carbon dioxide is 50-60 kg/cm2.
