基于“教–赛–科”协同育人的化工工艺热风险及评估教学创新——Aspen Plus驱动的课程改革与实践

Innovation in Chemical Thermal Risk Assessment Teaching Based on “Teaching-Competition-Science” Collaborative Education—Curriculum Reform and Practice Driven by Aspen Plus

摘要: 项目以化工安全工程专业的必修课程化工工艺热风险及评估课程为例，引入了Aspen Plus化工流程模拟软件中的反应器模块，以乙酸乙酯和异丙苯合成过程为教学案例。在两个案例教学中分别采用了全混釜反应器和平推流反应器进行设计，针对设计过程中使用Aspen Plus软件自带的Model Analysis Tool工具来设计满足生产要求的操作条件，引入过程路径指数对模拟结果的安全性进行了评估，从教学结果可以看出，在融合了流程模拟软件以后的课程，将繁杂的理论公式以可视化的模型展示出来，可以充分激发学生的学习兴趣、调动学生的积极性，从理论知识到工程设计应用进行了全方位的学习，进一步，通过竞赛来深化学生的整体学习效果达到“教–赛–科”协同育人的理念。

Abstract: This project takes the compulsory course of Chemical Process Thermal Risk and Assessment for Chemical Safety Engineering as an example. The reactor module in the Aspen Plus chemical process simulation software is introduced, and the synthesis process of ethyl acetate and cumene is used as a teaching case. In two case studies, a continuous stirred tank reactor and a plug flow reactor were used for design. In the design process, the Model Analysis Tool built-in Aspen Plus software was used to obtain operating conditions that meet production requirements. The process route index was introduced to evaluate the safety of the simulation results. From the teaching results, it can be seen that in the course after integrating the process simulation software, displaying the complex theoretical formulas in a visual model can fully stimulate students’ interest in learning and stimulate their enthusiasm. It provides comprehensive learning from theoretical knowledge to engineering design applications, and the concept of “teaching-competition-science” collaborative education can be achieved by deepening students’ overall learning outcomes through competitions.
