Finally, the design determines the production process using high-pressure bulk polymerization method, and selects the appropriate EVA resin production materials accordingly , Additives and their production formulas, as well as the design of reasonable preparation schemes and equipment processes, etc., give specific process parameters about EVA production. And then,the amount of ethylene input per batch is 6293.06kg,and the amount of vinyl acetate input is 1398.458kg, and the amount of Acrylic input is 38.846Kg, the total mass of the produced polymer is 1932.591Kg, the process flow chart with control points is drawn according to the selected process flow route, and according to the actual Situation Feasibility analysis of the process route, pointing out possible problems and solutions. At the same time, according to the selected formula, the material balance, the heat balance and the size of the equipment are calculated. At last, this design also made corresponding plans for the three waste treatments, including waste gas treatment, waste water treatment and waste residue treatment.
