9.13 A distillation tower for a binary solution was designed with a partial condenser, using L0/D=1.0, as in Fig. 9.57a. When built, the piping was installed incorrectly, as in Fig. 9.57b. It was then argued that the error was actually a fortunate one, since the richer reflux would provide a withdrawn distillate richer than planned. The mixture to be distilled has all the characteristics of one obeying McCabe-Thiele assumptions. For a reflux ratio =1.0, reflux at the bubble point, and the (a) arrangement of Fig. 9.57b: (a) Sketch the Ponchon-Savarit and xy diagrams for the parts of the columns indicated in the figure. Label the indicated vapor and liquid concentrations. (b) Establish whether or not the distillate will be richer than originally planned
