To produce anhydrous alcohol by using azeotropic distillation have lots of merits such as continuous operation, less investment, lower energy consumption, high purity of product and so on. now It is the most popular process in anhydrous alcohol preparation. But in practical azeotropic distillation operations, a small fluctuation of operation process parameter may have great effect to the distillation's stability which would make the azeotropic point deflected and break the working conditions of azeotropy required.
