The Sanchez–Lacombe Equation of State (SL EoS) is used to model the solubility of different industrial alkane penetrants in polyethylene to explain the importance of considering different diluents for different processes, and the impact that this choice can have on operating conditions, especially for the production of linear low density polyethylene (LLDPE). Extension of this approach to ternary (ethylene/penetrant/LLDPE) systems shows the effect of composition of penetrant/ethylene mixtures on the solubility of such mixtures in LLDPE and swelling of the polymer phase at conditions of industrial relevance. This analysis reveals that using a constant polymer density instead of that predicted by the SL EoS can result in erroneous calculations of the particle size distribution developments in an olefin polymerization reactor.

催化气相烯烃聚合反应器过程建模的应用热力学

桑切斯-拉科姆状态方程（SL EoS）用于对不同工业链烷烃渗透剂在聚乙烯中的溶解度进行建模，以解释在不同过程中考虑不同稀释剂的重要性，以及这种选择对操作条件的影响，特别是对于线性低密度聚乙烯（LLDPE）的生产。这种方法扩展到三元（乙烯/渗透剂/ LLDPE）系统，显示了渗透剂/乙烯混合物的组成对这种混合物在LLDPE中的溶解度和在工业相关条件下聚合物相膨胀的影响。该分析表明，使用恒定的聚合物密度代替SL EoS预测的密度会导致对烯烃聚合反应器中粒径分布发展的错误计算。
