DISTILLATION CALCULATION BY THE MODIFIED PERTURBATION METHOD

Abstract

An unique perturbation method for the distillation calculation of a non-ideal system was proposed by Acrivos and Amundson. This method, however, is limited only to the first-order perturbation and gives an approximate solution, for the equation with the second and further perturbed terms is too complicated to use for practical purposes. To improve this point the Double Perturbation Method is presented here. Although the equations used in the presented method are obtained by the same reasoning as the above authors, this method, whose tiresome procedures can be overcome by computer, gives the strict solution.
