What Is a High-Pressure Compressor?

High-pressure compressor A type of compressor classified by pressure, with an exhaust pressure of 100-1000 MPa. Its models are available in piston, membrane, screw and centrifugal compressors. Generally used as petroleum gas, natural gas, oilfield gas compressors in the petrochemical industry, as hydrogen compressors in oil hydrofining, air in air separation, oxygen compressors, ethylene, propylene, propane, coke oven gas Compressors for processes such as nitrogen and ammonia.

Compressor (compressor), is a kind of driven

Compressor accessories are as follows ^[1]

High-pressure compressors are not equivalent to ordinary compressors, and the installation position is more important. The choice of installation site is the most overlooked by the staff. Often, the compressor will find a place after it is purchased, and it will be used immediately after piping. There is no prior planning at all. As everyone knows, such a hasty result, it will become difficult and difficult to repair the compressor in the future.

With the rapid development of oil refining, ethylene, chemical fertilizer and other industries in the world, high-pressure compressors have been widely used in the petrochemical process, and occupy a leading position. In particular, the large high-pressure compressors required in refining process equipment may have a maximum piston force of up to 1500 kN and a shaft power exceeding 15,000 kW. The reciprocating compressors commonly used in oil refining process equipment are mainly circulating hydrogen compressors and new hydrogen compressors for catalytic and cracking reformers and hydrogenation devices, and coking gas compressors for coking devices. Due to the different scale and process flow of high-pressure hydrogen compressors, and the corrosion of circulating hydrogen compressors and hydrogen sulfide and other media, it is difficult to manufacture, especially the rapidly developing new processes such as wax oil hydrogenation and residue hydrogenation, which use large high pressure compression Engine, the maximum piston force has reached 1250 kN, the exhaust pressure is as high as (17 ~ 19) MPa, and the single unit gas volume exceeds 90,000 Nm3 / h ^[2] .
