What is the best type of compressor (discharge: 6-8 bar) suitabel for Syngas which is under 1 atm?

Syngas is produced in a reactor at 1 atm. Then it is passed through a condenser where a pressure drops becuase of friction so goes under 1 atm. It need to be compressed afterwards upto 6-8 bar and...

Hi Anand,

If I understand your question correctly, you are trying to find how much should be the suction pressure of the compressor?

To calculate the suction pressure criteria with satisfying the discharge pressure, there are a number of references and standards. you can follow API 615 for centrifugal compressor according to polytropic equation of compressors. Alternatively, please take a look at Osiadacz book chapter 2
