Question: What is a good method of minimizing shell side pressure drop in a shell and tube exchanger?
Keywords: impingement,rods,minimize,shell,side,pressure,drop,distribution,shell,tube,exchangers,exchanger,heat
Answer: When shell pressure drop is critical and impingement protection is required, use rods or tube protectors in top rows instead of a plate. These create less pressure drop and better distribution than an impingement plate. An impengement plate causes an abrupt 90 degree turn of the shell stream which causes extra pressure drop.
