How to calculate the outlet temperature of the material in a heat exchanger
Thread Content
For a heat exchanger similar to a reboiler, the shell side is normally in a boiling state; the total heat input to the tube side can be calculated. The feed conditions on the shell side are known, as is the exit pressure. The fluid involved is an ethylene glycol aqueous solution, and a gaseous phase is present at the exit. How can the exit temperature be determined in this case? I don’t need to use software like Aspen; I’d like to do a simulation calculation using Excel. Could someone give me some guidance?
1. Since the outlet pressure is already known, the saturated steam temperature of ethylene glycol corresponding to that pressure should also be available for reference； 2. You said that the chamber is similar to a reboiler at the bottom of a tower; in fact, the inlet and outlet temperatures of the material are the same, with no phase change occurring inside the heat exchanger.
