1. It can be used as air power
After being compressed, air can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement in machining centers, etc.
2. It can be used for gas transportation
Air compressors are also used for pipeline transportation and bottling of gases, such as long-distance coal gas and natural gas transportation, bottling of chlorine and carbon dioxide, etc.
3. Used for gas synthesis and polymerization
In the chemical industry, some gases are synthesized and polymerized after the pressure is increased by the compressor. For example, helium is synthesized from chlorine and hydrogen, methanol is synthesized from hydrogen and carbon dioxide, and urea is synthesized from carbon dioxide and ammonia. Polyethylene is produced under high pressure.
4. Used for refrigeration and gas separation
The gas is compressed, cooled, and expanded by the air compressor and liquefied for artificial refrigeration. This type of compressor is usually called an ice maker or ice machine. If the liquefied gas is a mixed gas, each group can be separated separately in the separation device to obtain various gases of qualified purity. For example, the separation of petroleum cracking gas is first compressed, and then the components are separated separately at different temperatures.
