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.

Therefore, the study is significant both theoretically and practically. As a result, the studying aim of this paper is to establish a practical and complete system for the prediction of ship maneuvering motion, taking into account of the influence of the environmental factors, such as the wind, wave and current, establish a practical and complete system for the prediction of ship maneuvering motion. In this paper, the OpenGL virtual reality simulation technique is introduced into the field of ship maneuver and control, and using the MMG mathematical model, the three dimensional dynamic simulation system of the ship motion is established and good results are achieved. In the process of the system development, firstly, the maneuvering motion equations for ship in the still water are established, based on the MMG module mathematical model and serial experimental result. After compiling the program, the calculation results are compared with the experimental data, the coherence between them validate the mathematical model.
