and 80 mo separate a binary mixture of A and B by continuous distillation. The mixture consists of 20 molk A are pfotted in the the bubble point. The relative volatility of A to B is 3.0 and the vapor tliquid equilibrium data need them. The binary ed figure(s) Several copies of the figure are supplied for this problem in case you concentration of 95moly mixture is avaitable at 100mol/hr and we wish to obtain a distillate product that has a A and that contains hal of the component A in the feed stream. We wish to determine if we can use an existing distillation column that is no longer being used for its Original purpose. The column is equipped with a total condenser, a partial reboiler, and ten plates above the reboiler. There are only two possible locations at which the feed can be introduced without making modifications to the column. These locations are plate 5, counting up, and directly into the reboiler. The reboiler is equipped with steam coils that are capable of vaporizing up to 85 mol/hr of the liquid in the reboiler. Although the column is not what you would design, we would like to determine whether the column can be used, as is, to make the desired product. You are asked to consider two cases, the feed introduced at plate 5 (counting up from the bottom) and the feed introduced into the reboiler. Based on the above information consider the following two cases: (a) The feed is introduced at plate 5 (not likely to be the optimum location) and the reflux ratio is set to four. Show the operation lines for this reflux ratio and show the equilibrium stages stepped off on a McCabe-Thiele diagram with the feed on plate 5 and a total of ten plates plus the reboiler. Can the column be operated at this reflux ratio? Does the reboiler have adequate capacity? Is it acceptable to make a distillate that is purer in component A then specified. (b) The feed Is introduced directly into the reboiler. Can the column now be operated at a reflux ratio of four? Demonstrate the validity of your answer graphically
