Abstract

The ability and capability to analyze and benchmark alternative designs on top of the optimal network are deemed valuable competencies for current and future chemical engineers. In this context, a process graph (P-graph)-inspired tool – P-HENS is introduced to an integrated plant design unit in an undergraduate chemical engineering degree program at Swinburne University of Technology Sarawak Campus in Malaysia. The energy recovery aspect is one of the key design elements in the integrated plant design unit. The introduction of P-HENS, which is capable of mathematically determining multiple optimal and sub-optimal solutions is considered useful for the students to (i) identify plausible heat exchanger networks (HENs) structures that may be overlooked using conventional approaches and (ii) enable a more in-depth analysis to justify the selected design. Overall, the implementation of P-HENS shows positive outcomes, where this free-of-charge software complements the learning of conventional manual approaches used in HENs synthesis. Furthermore, recommendations suggested by the users (students) are collected and compiled for potential future software development. This work serves as an essential reference for other chemical engineering educators who are teaching pinch analysis or heat integration-related courses.

通过图论工具实现换热器网络综合的深入分析:Swinburne理工大学砂拉越校区的经验
对当前和未来的化学工程师来说,在最优网络之上分析和基准设计的能力和能力被认为是有价值的能力。在此背景下,在马来西亚斯威本科技大学沙捞越校区的本科化学工程学位课程中,一个受过程图(P-graph)启发的工具- P-HENS被引入了一个综合工厂设计单元。在综合装置设计单元中,能量回收是关键设计要素之一。P-HENS的引入,能够在数学上确定多个最优和次优解决方案,被认为对学生(i)识别可能被传统方法忽视的合理的热交换器网络(HENs)结构(ii)能够进行更深入的分析,以证明所选设计的有效性。总的来说,P-HENS的实施显示出积极的结果,这种免费的软件补充了在母鸡合成中使用的传统手工方法的学习。此外,收集和汇编用户(学生)提出的建议,以供将来可能的软件开发。这项工作为其他化学工程教育工作者教授夹点分析或热集成相关课程提供了重要的参考。

期刊介绍: Education for Chemical Engineers was launched in 2006 with a remit to publisheducation research papers, resource reviews and teaching and learning notes. ECE is targeted at chemical engineering academics and educators, discussing the ongoingchanges and development in chemical engineering education. This international title publishes papers from around the world, creating a global network of chemical engineering academics. Papers demonstrating how educational research results can be applied to chemical engineering education are particularly welcome, as are the accounts of research work that brings new perspectives to established principles, highlighting unsolved problems or indicating direction for future research relevant to chemical engineering education. Core topic areas: -Assessment- Accreditation- Curriculum development and transformation- Design- Diversity- Distance education-- E-learning Entrepreneurship programs- Industry-academic linkages- Benchmarking- Lifelong learning- Multidisciplinary programs- Outreach from kindergarten to high school programs- Student recruitment and retention and transition programs- New technology- Problem-based learning- Social responsibility and professionalism- Teamwork- Web-based learning
