On the basis of summarizing separation method of acetic acid-water system, we studied the azeotropic distillation process of acetic acid-water system, selecting butyl acetate, isobutyl acetate and isopropyl acetate as entrainers. The influence of packing height, ratio of water to entrainer and acetic acid initial concentration to separation effect of azeotropic distillation was studied in detail. Simulation calculations of general distillation and azeotropic distillation were carried out. The influence of reflux ratio, theoretical plate, feed position, feed temperature and feed concentration to distillation process were discussed. Preferred process operation parameter, which had guiding meaning to practical production of distillation process were obtained. Basic data for the process amplifying design of azeotropic distillation tower were provided. Invest and operation energy consumption of two distillation methods were compared. The elementary technical design of azeotropic distillation tower was carried out on the basis of result of simulation calculation. The type of major auxiliary equipments and inner parts of packed tower were selected.The research results are as follows:(1) Butyl acetate, isobutyl acetate and isopropyl acetate could be selected as entrainer, and separation effect was near.
