英文摘要	采用POlyMErS PluS软件对HyPOl聚丙烯工艺进行了模拟。建立了与现场流程及POlyMErS PluS软件均相匹配的模拟流程;采用PC-SAfT状态方程,并根据zIEglEr-nATTA催化体系的丙烯聚合机理,确定了丙烯聚合动力学。此外,通过文献提供的现场数据分析并确定了丙烯聚合动力学参数。最终建立了完整的HyPOl工艺流程模型。以采集的工业数据对模型进行验证,并采用模型考察了工业稳态操作下的主要工艺条件对丙烯聚合过程的影响。结果表明,模拟结果与工业现场采集数据比较吻合。随着H2进料量增加,聚合产品的熔融指数(MI)增大,数均相对分子质量(Mn)及其多分散分布指数(PdI)下降;催化剂及丙烯进料量的增加都将使各反应釜的聚合物产量增加。; The HYPOL technology of polypropylene was simulated by Polymers Plus.First,a flowsheet which incorporates the actual technology into Polymers Plus was obtained.In addition,based on the perturbed-chain statistical associating fluid theory(PC-SAFT) and the propylene polymerization mechanism catalyzed by Ziegler-Natta catalyst,the propylene polymerization kinetics was obtained.Simultaneously,the polymerization kinetic parameters were obtained through the industrial dada provided via literature.Accordingly,the whole process model of the HYPOL technology was developed.The comparison between the simulated and plant data showed that they were in good agreement with each other.The model was also used to investigate the effects of the main operation parameters on the propylene polymerization under steady-state condition.The results indicated that the polymer melt index(MI) increased and the number average relative molecular mass(Mn) of the polymer and its polydispersity index(PDI) both decreased with the increase of the H2 flow rate.The polymer yield increased with the increase of the feed flow rate of catalyst and propylene.; 中国石油天然气股份有限公司兰州石油化工研究中心资助项目
