In Zhejiang University’s Aspen tutorial, how is the optimal reflux ratio determined for the distillation column DSTWU model?

It is possible to create a curve showing how the reflux ratio changes with the number of trays, but how can a compromise be found between the number of trays and the reflux ratio to achieve the optimal result? What are the reference principles? Can this model alone solve it? Thank you all~
Reply to 1# tdsongyang: Give sensitivity a try. I’m also working on it; let’s exchange ideas.
It’s 1.2 times the minimum reflux ratio, right? The minimum reflux ratio is a design specification that determines the number of trays to be such that the reflux ratio no longer increases; this is the minimum reflux ratio
This would involve equipment investment and operating costs, right?
By examining the effect of N and R on the recovery rate, the optimal reflux ratio can be determined.
