摘要/Abstract

摘要：

利用Aspen Plus化工流程模拟软件对百万吨乙烯装置丙烯精馏单元进行稳态模拟。通过对丙烯精馏塔操作优化多变量影响因子的研究，对比分析了模拟优化次序对丙烯精馏效果的影响，确定了更为合理的丙烯精馏塔操作优化模拟步骤：“模拟输入初值的确定-最佳塔底采出量范围-最佳质量回流比的确定-其他优化参数”，并利用此前最佳优化值作为新的模拟输入初值继续进行其他参数的优化，为实际操作提供更加准确合理的操作参数。

Abstract:

Steady-state simulation was carried out for the propylene distillation unit in a 1000 kt/a ethylene plant by using Aspen Plus software. The multivariable impact factors for the operation optimization of propylene distillation tower were discussed, and the influence of simulation optimization orders on propylene distillation efficiency was analyzed. More reasonable simulation steps were determined for the operation optimization of propylene distillation, i.e., the determination of initial value of analog input, the scope of optimum tower bottom yield, the determination of optimum mass reflux ratio and the other optimization parameters, and the previous optimum value was used as a new initial value of analog input in the optimization of other parameters. More accurate and reasonable operation parameters can be provided for the actual operation.
