Abstract

Abstract: A method to select solvent for extractive distillation is proposed by UNIFAC group contribution. Solvent selectivity can be divided into two parts: the partial combinatorial solvent selectivity and the partial residual solvent selectivity. The properties of partial combinatorial and residual solvent selectivity are demonstrated. In most cases,the partial residual solvent selectivity is predominant. The candidate groups of solvent can be selected by group interaction parameter using UNIFAC group interaction parameter table as a guide.

Key words: solvent selection, solvent selectivity, UNIFAC, group contribution, extractive distillation
