以重整抽余油为原料，采用实验与工业模拟相结合的方法对其加工生产99%异己烷、95%正己烷、95%正庚烷溶剂油进行了研究。实验优化了加氢脱烯烃脱芳烃操作条件，对加氢产品精馏得到了符合指标要求的产品；采用Aspen Plus软件设计了5种精馏过程并以全年总投资费用（TAC）最低为目标进行模拟优化。结果表明，在温度150℃、压力1.0 MPa、氢油体积比350：1、液时空速2.0 h^-1时，加氢产品烯烃及芳烃质量分数最低；优化后精馏过程全年总投资费用（TAC）为750.2万美元/a。该流程中的异己烷塔采用热泵精馏技术，可使该塔的能耗降低40.89%，TAC减少32.14%。

A method combining experiment with industrial simulation is employed to study the production of high purity solvent oil,such as 99% iso-hexane,95% n-hexane and 95% n-heptane,from the reformed raffinate oil.The operating conditions of hydrogenation reactions for removing olefins and aromatics are optimized through experiments,and qualified products are obtained by distillation of the hydrogenated products.Meanwhile,five kinds of distillation processes are designed by using Aspen Plus software,and simulated and optimized by taking the lowest total annual cost (TAC) as the optimization target.The results show that the contents of olefins and aromatics in the hydrogenated products are minimum when the reaction temperature is at 150℃,the reaction pressure is 1.0 MPa,the volume ratio of hydrogen to oil is 350 and LHSV is 2.0 h^-1.TAC of the optimized distillation process is US $7.502 million per year.The heat pump technology is applied on iso-hexane tower in the optimal process,which can decrease the energy cost by 40.89% and TAC by 32.14%.
