2. Assuming a feed of xF=0.45 at 10 bar at the bubble point, we want to achieve an xD=0.70 and xW=0.03 with a reflux ratio at 1.25Rmin, answer the following: (a) Draw the 2 operating lines using the information provided (note: do not try to derive them like we have done in class, just use the information provided above. Recall the relationship between the operating lines and the feed line) (b) What is the minimum number of stages assuming total reflux? (c) What is the reflux ratio? [Hint : reflux ratio is related to the slope of one of the operating lines - use that relation] (d) How many actual trays would you have with a total condenser and reboiler? (e) At what tray would you place the feed? f) Are the distillate and bottoms products liquid or vapor? g) Can we achieve a separation with xD=0.8 and xW=0.03
