乳液丁苯橡胶工艺流程模拟 摘要 丁苯橡胶是合成橡胶中工业化最早、产耗量最大的胶种，被大量用于制造各 种汽车轮胎、胶管、运输带及胶鞋制品的橡胶产品.它主要分为乳液丁苯橡胶 （E-SBR ）、溶液丁苯橡胶 （S-SBR ）和热塑性丁苯橡胶 （SBS ）三大类。目前， 工业上丁苯橡胶的生产方法主要采用乳液聚合和溶液聚合两种方法。乳液聚合生 产工艺成熟，生产规模大，其生产能力约占SBR 总生产能力的80%以上。选用 大型化工流程模拟软件ASPEN PLUS ，运用其中Polymer Plus 模块中灵敏度分析 功能对乳液丁苯聚合过程进行了模拟，以期得到符合设计要求的最优化方案。最 后完成物料衡算和热量衡算，检验最优化方案在实际工厂运用中的可行性，并依 此绘制工艺流程图和聚合釜工艺装配图。 关键词：丁苯 乳液聚合 工艺流程 Aspen plus 灵敏度分析 III 乳液丁苯橡胶工艺流程模拟 ABSTRACT SBR is the first synthetic rubber in the industrialized production of plastic consumption of the largest species and were widely used in the manufacture of various automobile tires, hoses, transport belt and shoes manufactures rubber products. It is mainly divided into emulsion styrene butadiene rubber (E - SBR), solution styrene butadiene rubber (S-SBR) and thermoplastic styrene butadiene rubber (SBS) three categories. At present, the industrial production of styrene-butadiene rubber and emulsion polymerization method used mainly solution polymerization two ways. Polymerization mature production technology, production scale, their production capacity of about SBR total production capacity of more than 80 percent. A popular chemical technology simulation software in the world, Aspen Plus is chosen, which has been developed by Aspen Tech Inc. It is used to simulate the emulsion polymerization process by the sensitivity analysis in the polymer module of it, then obtain the optimization design project. Finally completed the calculation of mass balance, heat balance, checked the feasibility of the optimization in the factory practice and finished the technical flow sheet and the polymerization apparatus drawing.
