Common compressors used in liquefied natural gas devices include centrifugal compressors, screw compressors, piston compressors, etc.

Liquefied natural gas (LNG) is a type of natural gas that is liquefied and compressed at a specific temperature. It has the advantages of high storage density, low cost and environmental protection, and has been widely used in the energy field. The compressor in the liquefied natural gas device compresses natural gas into liquid and is the core equipment in the entire system. There are various types. The following are some commonly used ones:

一、Centrifugal compressor

The centrifugal compressor is the most widely used compressor in liquefied natural gas devices and is suitable for occasions with large gas flow. Its main features are small size, light weight, stable operation, low vibration and low noise. It is suitable for various occasions such as offshore LNG devices or LNG vehicles.

二、Screw compressor

Screw compressor is another commonly used compressor in liquefied natural gas equipment. It is suitable for occasions with small gas flow. Compared with centrifugal compressors, screw compressors are larger in size, but they have higher efficiency, higher compression ratio, and lower maintenance cost. They are suitable for occasions such as large LNG transmission pipelines or gasification stations.

三、Piston compressors

Piston compressor are also commonly used in liquefied natural gas plants. Their main features are longer length, heavier weight, and higher output pressure. They are suitable for occasions where there is a greater need for short-term gas compression.

In addition, there are other types of compressors such as axial flow compressors and diffusion compressors for specific occasions.

In summary, different types of LNG units require different types of compressors to support them, and relying on only one type of compressor often cannot meet the needs of all units. Therefore, in the design and construction of LNG units, it is necessary to make choices based on actual scenarios.
