Condition Optimization for Separation of Methanol-Acetone Binary Azeotrope by Extractive Distillation

For separation of methanol- acetone binary azeotrope by extractive distillation with extractive solvents of water and monoethanolamine( MEA),experimental study on separation of mixture of methanol and acetone by extractive distillation was made for the sake of condition optimization. Changing conditions of the position of feed- stage,the temperature of extract solvents,the ratio of extract solvent to feed and the reflux radio while other conditions were identical,optimum conditions under different reaction conditions were obtained. Besides,the separation effects of the two ways were analyzed.
