| 摘 要： | 利用ASPENPLUS软件，对石油芳烃常规分离塔系的工况进行了模拟计算，提出了两种芳烃热集成精馏流程。通过工艺分析和模拟计算确定了两种热集成精馏的最佳工艺操作条件。在模拟计算的基础上，通过对常规精馏与热集成精馏的能耗比较和设备投资的经济分析，找出了较为合理的一种三塔构型有效节能流程。研究结果表明，该流程可节约供热量37%，热力学效率可提高3.56%，但换热面积需增加1倍。

| Abstract: | The simulation of BTX conventional distillation was performed with ASPEN PLUS software, and two kinds of heat integration of BTX distillation were proposed. The configurations with minimum energy requirement of the proposed flowsheet were determined by technics analysis and simulation calculation. Based on the results, a reasonable three-column flowsheet was obtained by comparison with conventional distillation on energy consumption and investment of equipment. The research results show that the heat integration flowsheet of BTX distillation can save steam consumption by 37%, increase thermodynamic efficiency by 3.56%, but increase heat exchanger area by 100%, and it is an effective energy-saving one. |
