乳液聚合丁腈橡胶聚合过程的稳态模拟

运用美国Aspen Tech公司研发的Polymer Plus软件模拟乳液聚合丁腈橡胶生产中聚合部分的流程,通过对热力学参数的拟合和反应动力学参数的调整,建立了牌号为N41的丁腈橡胶聚合部分的模型。8个反应釜的模拟结果表明转化率、丙烯腈结合率和数均相对分子质量均符合乳液聚合机理的特性,与生产现场实验室分析结果能较好地吻合,相对误差在4%以内。将此热力学和动力学参数系统应用于牌号为N32的丁腈橡胶的模拟过程中,对参数的准确性进行考察,结果表明反应模型具有较好的适应性,模拟结果与实验室分析结果的相对误差在5%以内。

Steady-state simulation of emulsion polymerization process in acrylonitrile-butadiene rubber production

Using software Polymer Plus, the steady-state simulation of emulsion polymerization process in acrylonitrile-butadiene rubber(NBR) production was conducted. The reaction model for NBR 41 was established through adjusting thermodynamic parameters and reaction kinetic parameters. The simulation results for 8 reactors showed that all conversion, bound acrylonitrile and relative molecular mass could meet the emulsion polymerization mechanism and coincide with analysis data in production with relative error below 4%.The reaction model was applied to NBR 32 to verify its accuracy,and the results indicated that the model was satisfied for NBR 32.
