There are MANY diferent brands of process oil flooded screw compressors: Howden, Mycom, Aerzen, GHH, Kobelco, Tamrotor to name a few. Only a couple have a "compound" machine (Mycom & Kobelco). Kobelco & Mycom offer factory direct packaging of their unit (noting that packaing costs...
Be careful when turning a centrifugal comrpessor into a pump. We all know they are not designed for such service.
The liquid is a larger mas flow and as such you could greating affect your power draw.
Erosion will always occur as the liquid partical in a centrifugal compressor will never...
Depending on where the "Design" loading of your compressors are, you may be able to switch. You probably know that the evap coolers lower the condensing temperature of the refrigerant. If you use straight air-cooled HX (no evap), then you lessen the "tonnage" (you have...
As stated before, economics is a play.
My company can do this with a recip and that is typically used for this application (looks like acid gas injection). A centrifugal is not practical with the number of stages. IF you want to break it up into two machines, we may put a screw compressor on...
Mark,
Yes, positive displacement compressor will give you the same volume (displacment), and I think that you can apply the N2 machine to CO2 service for the compression application keeping in mind the following:
1) Temperature:
N2 has a k-value (Cp/Cv) of 1.4, while CO2 is closer to 1.3...
