How to handle phase change heat in Aspen HX-net
Thread Content
I’m new to HX-net, and I noticed that in the Process Stream interface there is a column labeled Effective Cp. By checking the help documents, I learned that this column represents the effective heat capacity. However, I’m not quite sure what the meaning of this \"effective\" heat capacity is – is it some kind of correction applied to Cp? Additionally, Cp is used to calculate the sensible heat, but what happens to the latent heat of phase change HX-net if a stream undergoes a phase change during the matching process? Has it been adjusted to that Effective Cp? I earnestly ask fellow travelers for their advice.
Double-click on Logistics, use Insert Segment to add different temperature ranges; specify the Cp value or heat load for each range, and the program will automatically calculate the total effective Cp value or heat load for you.
Could ls explain how to divide temperature ranges? I’ve been struggling with this issue for a long time now!
I mean, I don’t know how to divide the temperature zones in order to calculate CP; I hope everyone can help solve this issue.
