What is the approximate value of the LMTD correction factor for heat exchanger calculations?
Thread Content
Hello, experts: When using Aspen to calculate heat exchangers, the LMTD correction factor in the results is only 0.34 – is this too low? If it is too small, how should it be adjusted?
It’s probably due to temperature crossover; one needs to make a judgment call on their own
Amazing, you hit the nail on the head right away; there is indeed a sense of warmth and connection. Currently, the focus is on performing calculations for this single heat exchanger (a single heat exchanger with multiple tube passes). The liquid petroleum gas flows through the tube side, while hot water flows through the shell side. During Aspen simulation, temperature cross-over occurs, but no warning messages appear in the simulation results; this shouldn’t happen. It’s really confusing.
Specific issues need to be analyzed on a case-by-case basis
