Thank you for your video. This is really helped me. But I'm still confused at the reflux part, if we want to design distillation using this method are we decided the number of reflux by ourself? Or there is a rule for that?
Thank you for your kind words! Typically within the design stage we can decide upon the reflux ratio prior to the design. If our target values aren't met then we can revise. It's usually best to go for a reflux of 1 as an initial guess, unless you have other information based on product quaility/purity. I hope this helps!
A q-line greater than 1 indiactes you have a subcooled liquid and it will simply alter the slope/gradient of the line. From the plot you can keep it's initial co-ordiante as the intersection of the feed entry point with the x=y line.
