combined feed exchanger
combined feed exchanger
(OP)
we have a combined feed exchanger to preheat the reactor feed and cool the reactor effluent it is single pass counterflow shell and tube heat excahngerit is not giving proper efficiency how can i increse the efficiency of the exchanger . the feed is hydrogen + (nC10-nC13) cut





RE: combined feed exchanger
If done recently, you may be able to help the situation by installing "turbulators" (tubeside static mixers), provided these don't impose too great a pressure drop.
Hope this helps.

RE: combined feed exchanger
i have the same problem wth the sam exchanger,the exchanger is new and have a mixing nozzel to mix the hc with hydrogen.
i think that the problem with the over att heat transfer cof.calcolations,can you help me to check the exchanger calculations to fixe the exchanger problem.
thanks
