The separation of a binary heteroazeotropic mixture (1-butanol – water) by batch distillation is studied in a new Double-Column System (DCS) by pilot plant experiments and dynamic simulation performed with a professional flowsheet simulator. The DCS is operated in closed mode. At the end of the process products of high purity were obtained with high recoveries in the reboilers. However the limited facility of setting accurately the ratio of the reboiler heat duties caused difficulties concerning the optimal operation of the new system
