摘要 溶剂油是石油化工重要产品，其生产基本由精馏分离序列完成，通过优化精馏序列内分离任务和操作参数可有效提高各类溶剂油产品收率，降低单位产品能耗。在流程模拟软件Aspen Plus中建立溶剂油分离模拟流程，利用DUSTWU简洁计算模型确定各个精馏塔的初值，之后使用RADFRAC严格计算模型，利用单因素变量法对主要精馏塔的工艺参数进行调整和优化。研究主要操作参数，如回流比、进料位置和采出量等对于精馏塔能耗的影响，最终得到最适宜的溶剂油分离流程。

Abstract： Solvent naphtha is one of the most important petrochemical products. Distillation separation sequence is the main method to produce different solvent naphthas with varied characteristic. Adjusting the ratio of different products and operating parameters in the distillation separation sequence can effectively improve the yield and quality of these products, and also save energy. Establishing the simulating model in Aspen Plus, the performance of the distillation scheme for separating solvent naphtha was investigated by the method of process simulation. Based on the separating object, the initial operating parameters of the distillation columns were calculated by the DUSTWU model. Then, by adopting the RADFRAC model, the optimizing process of the operating parameters of the distillation columns was completed by the method of univariate analysis. Reflux ratio, theoretical tray number, feed stage position and distillation rate were the main operating parameters to be studied, and the optimized solvent naphtha distillation separating scheme was finally obtained.
