bcs5274 Yes, they are in series and each compression stage(train) feeds the other one till it compress the gas to 2000psi. I think a 4 throw frame would be enough for our purpose, because it's hard to achieve 25-50-75% unloading on a 6 throw frame if we going to use the valve unloaders only.

Drivers are electric motors and speed control is possible. But because of vibration and resonance problems of variable speed drivers in different operating points of compressors we are affraid of them and prefer to use VFDs for centrifugal compressors. Reducing the suction pressure is...

Hi everyone How can I practically calculate centrifugal pumps horsepower and size the electric motor driver? including all mechanical losses of the pump and coupling and all other factors related to electric driver.

Each Train consists of 3 reciprocating compressors (2 working+1 standby) and final train compress the gas to about 2000psi. So considering the capacity of compressors (each about 15000 kg/hr depending to the stages), increasing the number of compressors doesn't seem economic, but it is practical...

Good Day I'm working in an engineering company and one of our projects is a gas compressor station which includes 4 trains of reciprocating gas compressor. Currently we are in detailed engineering phase of that plant. The issue that we have in most of our projects (which are mainly gas...
