E^V-matrix Method for Solving Multicomponent Distillation Problem by Considering Partial condensation and Entrainment

Abstract

A matrix method is proposed to obtain a further rigorous solution in practical use of multicomponent distillation problems of the operation type by considering both partial condensation of vapor, which is caused by the heat loss through the column wall, and liquid entrainment from the plates. In this method a direct iteration approach is used for the terms related to the partial condensation and entrainment with the E^V-matrix method of Yamada et al. The usefulness of the proposed method is illustrated by a numerical example of quaternary n-paraffin system, and the effect of partial condensation and entrainment on vapor and liquid loads through the column is also illustrated.
