I need to specify a water cooled exchanger.
The problem is that I have an elevated temperature difference between tubeside and shellside, and temperature cross.
The conditions of service are as follow:
Tubeside - high pressure N2/H2 mixture (gas, no condensation) 6868 kg/h, Tin/out= 168/40ºC...
From a practical point of view, I need to know how much heat can/should be extracted from a reciprocating compression stage through its jacket water. As far as I know, jacket water in compressor cylinders only serve to keep metal temperatures in an acceptable range, not to cool process gas.
i.e...
