Issues with the outlet pressure of reciprocating compressors
Thread Content
I would like to ask everyone: What determines the outlet pressure of a reciprocating compressor? In a methanol synthesis system, the design pressure for the fresh gas compressor is 5.2 MPa; currently, it operates at 4.8 MPa. I hope to reach the design value, but the equipment indicates that the pressure is related to the pressure in the synthesis system. If the system pressure remains unchanged, it’s difficult to increase the compressor pressure. Isn’t the system pressure determined by the compressor’s outlet pressure?
The outlet pressure of a reciprocating compressor is determined by the back pressure; the pressure in the subsequent synthesis system builds up first, and this is what is referred to as system surge!
Design pressure is the pressure that your air compressor can withstand. The outlet pressure is determined by the back pressure; there is no pressure in the open condition. Without backpressure, it’s impossible to generate pressure
