AB - This poster presents a design method of multicomponent distillation columns that offers the possibility of solving the equilibrium equations and the mass and enthalpy balances by a rigorous method and different approximate methods, optimizing, by the simplex algorithm, the distillate flow rate for a specified product separation and calculating the number of stages and the optimum feed location. New methods for the calculation of the minimum reflux ratio for multicomponent distillation columns are also presented. The main problem involved in the rigorous calculation of the minimum reflux ratio is the great number of iterations involved, each one requiring the calculation of a distillation column. Nevertheless, this search can be orientated and simplified on considering the conditions that must be fulfilled in such an operating condition. In accordance with this, four different methods have been suggested, based in the desig method of distillation columns for multicomponent mixtures.
