MINIMUM TOTAL VAPOR CAPACITY OF BATCH DISTILLATION OF BINARY MIXTURE UNDER TOTAL REFLUX AND TOP ACCUMULATION
Algorithm of the minimum total vapor capacity of batch distillation of ideal binary mixture under total reflux and top accumulation and ideal operation condition is developed.A function f(x D) [equation(7)]is set up and transformed into g(x D)[equation(10)]in order to determine that the instantaneous constant region is on the top(or in bottom).For designed separation task,the method for determining the interval of x D in which the instantaneous constant region is on the top(or in bottom)and the equations for calculating minimum total vapor capacity are derived.
