摘　　要：运用Aspen Plus软件,以BK10为热力学方法,对50万t/a常压装置进行模拟优化研究。通过与标定数据对比分析,验证了模拟计算的可行性。基于现场条件及控制改造成本等因素,提出了"闪蒸塔+常压塔"替代"初馏塔+常压塔"改造方案,并对改造后的方案进行了换热网络优化,同时提出了优化措施。模拟结果表明,改造后的方案轻油收率提高7.15%,冷负荷降低26.89%。Selecting BK10 model as simulation method,the technical revamping of a 500 000 t/y atmospheric distillation unit is simulated and optimized by Aspen Plus. The feasibility of the simulation is verified by comparing with the calibration data. Based on the factors such as site conditions and cost control,the scheme of ＂flash column atmosphere distillation＂instead of ＂prefractionator atmosphere distillation＂is put forward. An analysis of the modified design scheme for the heat exchange network optimization is also performed. The optimization measures are proposed at the same time. The simulation results show that the yield of light oil is increased by 7. 15% and the refrigeration duty is reduced by 26. 89%.
