| Abstract: | In order to find out effective solvents in extractive distillation,relative volatilities were calculated by means of the Flash unit in Aspen Plus 10.2 simulator.Two Flash operational types and some different thermodynamic models in phase equilibrium were considered respectively.For an acetic acid-water system,the relative volatility of water to acetic acid was given by this method.N-methylacetamide and sulfolane were selected as(effective) solvents,which have relatively high volatility values.Furthermore,VLE phase diagrams for acetic acid-water-solvent systems were obtained to observe the effect in the whole range of concentration.A binary system of N,N-dimethyl formamide-acetic acid was also calculated,showing the formation of a binary azeotrope. |
