Gentlemen,

I installed ASPEN exchanger design and rating recently. Currently, I’m trying to be familiar with it by simulating the existing exchanger in the plant I work for. I developed a simulation model for shell and tube heat exchanger based on the available data sheet. When I run the model, error message went up that the heat load between the hot fluid and cold fluid is not consistent. I would like to know how can I resolve this error.

Another problem that the hot fluid passes the heat exchanger from the tube side not the shell side while the cold exchanger passes the heat exchanger from the shell side not the tube side. ASPEN EDR only has the tube side for the cold stream and the shell side for the hot stream. I would like to know if I could change that in ASPEN EDR.

Thanks
