基于Aspen Plus耦合生命周期评价的科研案例在环境工程原理教学中的应用

Application of Scientific Research Case in Teaching of Principles of Environmental Engineering Based on Aspen Plus Coupled with LCA

将化工流程模拟Aspen Plus软件与环境影响评估领域常用的生命周期评价(LCA)进行集成应用,围绕环境工程原理教学中有关化工过程质量能量衡算与环境污染防治内容的协同应用与拓展,构建化工流程模拟-环境风险评估科研案例“苯酐生产流程模拟及环境风险研究”,并将其作为环境工程原理的综合教学案例。教学实践经验表明,通过引入工程相关综合教学案例,不仅使得抽象的理论知识更加生动具体,而且在深化学生对课程理论知识理解的同时,提高学生应用专业知识分析和解决化工生产环境污染工程问题的综合能力和素质,为学生将来步入相关领域工作奠定扎实的基础。

Based on the cooperative application and expansion of course contents including the chemical process mass and energy balance and environmental pollution prevention, the scientific research of “study on production process simulation and environmental risk of phthalic anhydride” is built and used as the comprehensive teaching case for the course. During the teaching practice, the chemical process simulation software Aspen Plus combined with the environmental risk assessment tool “life cycle assessment”(LCA) is involved and introduced. The teaching practice shows that the introduction of engineering-related teaching case not only makes abstract theoretical knowledge more accessible and concrete, but also deepens students’ understanding of curriculum knowledge. More importantly, students’ comprehensive ability to analyze and solve the environmental pollution problems of chemical production by using the professional knowledge is strengthened, which lays a solid foundation for them to step into related fields in the future.
