A binary mixture has equilibrium curve as: y = 2.5x / (1+1.5x). The feed is saturated liquid, where the light component takes 40 mol%. If we want the top product to have 99mol% light component, what is the the minimum reflux ratio? Sketch the relevant lines/curves on the McCabe-Thiele diagram (equilibrium curve, feed line, and rectifying section operating line) Notes: 1. Make your sketch on a piece of paper (mark the lines/curves clearly), and write down your answer (minimum reflux ratio) on the same paper. Show the key steps of your calculation in order to receive partial credit. Submit a photo of the paper 2. While it would be helpful to make a sketch that is roughly to-scale, you do not need to be very accurate. The minimum reflux ratio should be calculated from the provided information instead of read from the sketch
