When the NRTL-RK method is used, the results show that the position of the feed plate is higher than the actual number of trays! I don’t know why.
The NRTL method will work; I’ve seen this kind of problem before
Oh, okay, thank you. The results obtained using IDEAL and NRTL-RK differ significantly.
