As stated in the previous section, for the azeotropic kind of mixture, the maximum achievable distillate concentration is limited by the position of the azeotropic point. Therefore, the purities imposed for each step of the process: low/high-pressurized column to achieve, 75%/35%, respectively. Next, the working conditions and predefined parameters are tabulated in Table , whereas LP/HP refers to low/high-pressure columns, respectively.
