Compressor
Thread Content
I am currently designing a high-pressure natural gas process that requires compressing natural gas from 2 MPa to 9.5 MPa, and I’m unsure whether to use a centrifugal compressor or a reciprocating compressor. Another issue is that the single-stage compression ratio of centrifugal compressors is roughly in that range; I remember that for reciprocating compressors it’s between 3 and 4. Moreover, a characteristic of centrifugal compressors is that the single-stage compression ratio is not high; however, I read in a document that the single-stage compression ratio for centrifugal compressors ranges from 2 to 4, which seems contradictory. Could some expert give me some advice?
It is recommended to read the \"Manual for Selecting Compressors and Drivers\" (compiled by Zhang Jianjie, Petroleum Industry Press).
Friend on the 2nd floor, are there electronic versions of the books you recommended? Can they be uploaded to the internet?
Reply to the friend on floor 4: Maybe I didn’t explain clearly enough; it’s already available in the forum, you can just search for it!
I read in another source that a single-stage compression ratio of 1.6 is preferable for centrifuges, which is the same as what my colleague said. I personally agree with the friend on the third floor
:Can a handshake be used with a diaphragm compressor???
If the owner is willing to spend the money, that’s fine; it mainly depends on the investor
The pressure is relatively high; it is recommended to use a screw compressor or a piston compressor!
In fact, the key lies in factors such as the volume of gas being processed and the pressure ratio. If the volume of gas is very large, exceeding the capacity of a single centrifugal compressor, it is possible to use two stages of compression after intermediate cooling
