Is it possible to install and safely operate a water cooler (trim-cooler, aftercondenser), downstream of the fin-fans and just upstream of the overhead drum, if outlet header from the fin-fans is 2m lower (closer to the ground) than the water cooler sheel-side inlet (process fluid inlet)? Process fluid - full range naphtha - consists of both condensibles and noncondensibles. Does this arrangement pose special hydraulic concerns, during design and operation?
Have an insight or suggestion?

Re: Safely operating a water cooler31 July 2006 at 1:29pmYes it is possible if a pressure differential in excess of the hydraulic loss of 2m plus frictional losses is maintained between the fin-fans and the overhead drum in order to maintain positive fluid flow. Normal considerations for two-phase piping systems should be employed.
