Abstract

We study the separation of the minimum homoazeotrope isopropanol - water by applying cyclohexane and n-hexane as entrainer in a new Generalised Double-Column batch heteroazeotropic distillation System (GDCS). First its feasibility is studied by a simplified method then we do 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 DCS. In each case we obtained shorter process durations and lower energy demands by the GDCS than by the DCS.
