How many do you know about the role and purpose of screw compressors?

Screw compressors are the core equipment of modern industrial production and are widely used in petrochemical, coal chemical, natural gas, metallurgical, power, mechanical manufacturing, and national defense industries. In addition, the demand for screw compressors in medical, textile, food, agriculture, transportation and other sectors is also increasing day by day. Screw compressors can provide power sources for pneumatic equipment and can also be used to increase gas pressure or transport gas, especially in petroleum and chemical production. Screw compressors are essential key equipment, and various gases can be used for the following purposes after increasing pressure through screw compressors:
1. The compressed gas generated by the screw compressor can be used as power
After being compressed, air can be used as power to drive various pneumatic machinery and tools, as well as control instruments and automation devices.
2. The compressed gas produced by the screw compressor can be cooled and gas separated
Gas is liquefied after being compressed and cooled, and is used for artificial refrigeration. This type of compressor is commonly referred to as an ice maker or ice machine. If the liquefied gas is a mixture, each component can be separated separately in the separation device to obtain various gases with qualified purity. For the separation of petroleum cracking gas, it is first compressed and then separated into different components at different temperatures.
3. The compressed gas generated by the screw compressor can be synthesized and polymerized
In the chemical industry, certain gases are beneficial for synthesis and polymerization after being pressurized by compressors. 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. Another example is the production of polyethylene under high pressure.
4. The compressed gas produced by screw compressors can transport gas
Screw compressors are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, and bottling of chlorine and carbon dioxide.
