Frontiers of Chemical Science and Engineering 2020, Volume 14, Issue 5,   Pages 824-833 doi: 10.1007/s11705-019-1867-3

Abstract: The traditional approach to solvent selection in the extractive distillation process strictly focuseson the change in the relative volatility of light-heavy components induced by the solvent.However, the total annual cost of the process may not be minimal when the solvent induces the largestThis work presents a heuristic method for selecting the optimal solvent to minimize the total annualThe results show that using the solvent with the minimal two-column extractive distillation index, the
