Dear all.

Hello. 

I have a question. Would you please help me?

In attached shell and tube twin parallel heat exchanger, Natural gas (NG) enters in tubes and propane enter in shell. Although both exchangers are completely the same, but propane level in exchangers are not equal, So the PRP-out temperature are not the same too. Why???

 

And surprisingly although PRP level in E-A is lower than E-B, but NG-out temperature in E-A is lower. Why???

 

One suggestion to overcome this issue is to connect both shell drain of heat exchangers, so they are like connected drums. What is your idea?
