mixture of 2 fluids in tube side of shell and tube condenser
mixture of 2 fluids in tube side of shell and tube condenser
(OP)
Hello every one
I am new to shell and tube heat exchanger design. I have water at shell side and methanol and methyl ester vapor at tube side , my question is
1. can we provide 2 different thermo-physical type of fluid at tube side in a single heat exchanger
2. If yes can some one provide me basic design calculation eg. of such type of case .I already done process design for shell and tube heat exchanger for water and one fluid at tube side.

Are the methanol and methyl ester vapors kept separate or are they a mixture?
Good luck,

Are these large diameter tubes (>1.5")?
Are the tubes vertical?
Condensing inside of small diameter tubes is very inefficient and can present some interesting flow issues.
Using mixtures is common enough that most chem process texts have examples.

yes i have mixture of both fluid which will condense .
tubes are of 1 " only
can be vertical or horiz. I am using HTRI for thermal design and it does not provide 2 input for tube side in STHE.it keep asking me prove vapour weight fraction and at this point i do not have that .

Process Heat Transfer by Kern has a chapter titled, "Condensation of Mixed Vapors". Most books on process heat transfer will.
