Problem 1 We Have A Column That Has A 6 Foot Section Of Packing The Column Can Be Operated As A Stripper With Liquid Fe 1 (28.78 KiB) Viewed 19 times

Problem 1 We have a column that has a 6-foot section of packing. The column can be operated as a stripper with liquid feed, as an enricher with a vapor feed or at total reflux. We are separating methanol from isopropanol at 101.3 kPa. The equilibrium can be represented by a constant relative volatility, a = 2.26. a) At total reflux we measure the vapor mole frac. of methanol entering the column, Yin = 0.650 and the vapor mole frac. of methanol leaving, Yout= 0.956. Determine noo and the average value of Hog- b) We operate the system as an enricher with L/D = 2. The vapor mole frac. of methanol entering the column, yin = 0.783 (this is the feed) and the vapor mole frac. of methanol leaving, Yout= 0.940. Determine nog and the average value of Hog.
