酮苯脱蜡是润滑油生产过程中的主要装置,而脱蜡过程中结晶状况的好坏直接影响脱蜡油的收率。上海高桥石化公司炼油厂与华东化工学院协作,采用过程优化的新方法——相关积分法,开发成功酮苯脱蜡溶剂比计算机优化控制系统。经一年多的工业试用、改进和完善,已在2~#酮苯脱蜡装置连续投用,不久前已通过技术鉴定。相关积分法是一种通用的系统稳态优化方法。它仅根据调优变量及目标函数随时间 Ketone-benzene dewaxing is the main device in the process of lubricating oil production, and the crystallization status of dewaxing process directly affects the yield of dewaxed oil. Shanghai Gaoqiao Petrochemical Company Refinery and East China Institute of Chemical Technology, the use of process optimization of the new method - related integral method, the development of a successful Ketone benzene solvent ratio computer optimization control system. After more than a year of industrial trial, improvement and improvement, 2 ~ # ketone benzene dewaxing device continuous investment, not long ago passed the technical appraisal. Correlation integral method is a universal system steady-state optimization method. It is based only on the tuning variables and the objective function over time
