Above is the heat exchanger I simulated using PROII. I would like to ask: what temperatures do LMTD/MTD refer to? How to determine whether the selected heat exchanger is suitable for the calculations
The problem is too complex; it is recommended to consult the process calculation manual for heat exchanger equipment
Thank you, I’ll read the book carefully. Where are all the mistakes? I hope you can provide some detailed guidance: handshake
