摘　　要：运用Aspen Plus对脱碳工艺中管壳式换热器进行模拟和优化,设计出符合国家标准的管壳式换热器.设计和模拟过程中,充分考虑各股物流的相态变化,利用Property Analysis模块生成物料相图,分析换热过程中的相变情况.结合手工计算,采用HEATER和HEATX模块简捷计算所需换热面积,初选出符合国家标准的管壳式换热器.在换热面积裕量及压力降许可范围内,调整参数变量,优化换热器.模拟优化结果表明:经过调整优化后,相同热负荷条件下,换热器实际换热面积节省21.4%.模拟和优化过程降低了实验费用,提高了工作效率.Shell-tube heat exchanger for carbon dioxide removal is simulated and optimized by Aspen Plus. The shell-tubeheat exchanger that accord with national standards is designed. During the design and simulation process, thephase transition of the material is fully considered. Phase diagram is calculated by Property Analysis module andthe phase transition process is analyzed. Coupled with the manual calculation, HEATER and HEATX shortcutmodule of Aspen Plus are carried out to calculate the acquired exchanger area. The shell-tube heat exchangerthat accord with the national standard is first selected. Within the limitations of the percent over design ofexchanger area and the pressure drop, the variables are adjusted to optimize the shell-tube heat exchanger. Theactual exchanger area decrease 21.4% on the same heat duty after optimization. The simulation and optimizationwill greatly reduce the cost of the experiment and improve the working efficiency.
