At present the production capacity of EPDM accounts for about 10% of the total production capacity of SR in the world. EPDM has wide range of application fields because of its excellent performance. Besides the traditional application fields such as auto industry, water-proof building materials, polymer modification, oil additives, electric wire and cable, athletic field and various mechanical parts, EPDM can also be used in food packaging, antimicrobial, heat insulation and inflaming retarding, and other elastomer products. It is annual output of 50,000tons of ethylene-propylene rubber device polymerization Section process design, the polymerization of ethylene-propylene rubber by solution polymerization process, the catalyst used for the vanadium oxytrichloride, vanadium, auxiliary catalyst is alkyl aluminum, solvent hexane. material balance, heat balance, reaction of a device such as the calculation finished based on the production principle of aggregation methods, process and other work ;including area of the hexane heater named E0203 is ??40.27 square meters, length of heat exchangers tube is 6 meters, the diameter of the reactor R0201 is 5.658met
