We study the separation of the minimum homoazeotrope isopropanol - water by applying cyclohexane as entrainer in a new Generalised Double-Column batch heteroazeotropic distillation System (GDCS). First its feasibility is studied by a simplified method then we did sensitivity analysis by rigorous simulation. The minimum duration is determined for the GDCS and for the original DCS, and their performances are compared. Due to its higher number of degrees of freedom the GDCS provides a more flexible operation than the original DCS. In each case we obtained shorter process durations and lower specific energy demands by the GDCS than by the original DCS
