摘　　要：加强精馏过程中的能量回收、优化工艺参数、提升安全水平,对精馏生产具有重要意义,这是化工专业学生学习的重点和难点,也是实际生产中重点关注的问题。基于兰州石化职业技术大学乙醇实训装置,对其存在的能量利用不合理、流程不完善等问题进行了分析,采用Aspen Plus软件进行了模拟与优化,并应用危险与可操作性分析(HAZOP)对安全风险进行了辨识,实施了改变塔顶冷凝方式、加强塔釜余热利用、优化进料位置、增加联锁保护等针对性的措施,改造成一套安全、节能的精馏装置。Strengthening the energy recovery,optimizing the process parameters and improving the safety level in the rectification process are of great significance to the rectification production,which is the focus and difficulty of chemical engineering students,and also the focus of attention in the actual production.Based on the ethanol training equipment of Lanzhou Petrochemical Vocational and Technical University,this paper analyzes the problems such as unreasonable energy utilization and imperfect process,adopts Aspen Plus software for simulation and optimization,and applies hazard and operability analysis(HAZOP)to identify the safety risks.Some specific measures,such as changing the condensation mode on the top of the tower,strengthening the utilization of residual heat in the tower reactor,optimizing the feed position and increasing the interlock protection,have been implemented to transform it into a set of safe and energy-saving rectification device.
