According to the industrial practice, methanol (MeOH) and iso-pentane (i-C5) can be separated by pressure swing distillation. Please answer the following questions: (a) The following figure is the designed process for separating these two components. From this process flowsheet, please conceptually sketch the Y-X diagram of these two components under pressure of 2.5atm and 13atm.(12%) (b) Please conceptually construct the possible flowsheet if a new mixture containing 80% and 20%MeOH (with the same molar flowrate) is separated by this technique ( 8% ). [No need to compute the process details] According to the industrial practice, methanol (MeOH) and iso-pentane (i-C5) can be separated by pressure swing distillation.
