In the preliminary stage of chemical process design, the choice of chemical reaction route is the key design decision, and the concepts of atom utilization and environmental quotient have become extremely useful tools. However, the waste quality such as chemical toxicity and other engineering factors have not been taken into account. Therefore, a synthetic route selection index, /Route, is proposed to determine the suitability of a chemical route in this paper. /Route considers the effects of “extended atom economy”, material renewability, chemical characteristics and some engineering factors. The extended atom economy concept regards not only the value of the desired product but also the value of byproducts. The methodology by using IRoute to compare different routes is illustrated in case study of cyclohexanone oxime and acrylonitrile manufacture. 相似文献

This paper summarizes the work of the EFCE Working Party Education (WPE) over the last decade and attempts to identify effective educational solutions to meet the challenges caused by the rapid rate of change in technology and society world‐wide. The paper uses the results of the 1994 WPE survey of curricula in European Chemical Engineering Universities to identify a first degree level core curriculum. The problem of how to adapt the discipline to meet technological and societal changes without losing its identity is addressed. Basic sciences, chemical engineering science, integrated systems design and holistic thinking are emphasized as essential elements of the discipline. The paper discusses how Safety, Health and Environment (SHE), biotechnology, computerized models, product design, sustainability and other new subjects have been incorporated into chemical engineering curricula since the original survey. A simple model of the education process is presented to indicate how students might obtain a chemical engineering understanding and mindset. The paper explains how chemical engineering evolved from its origins in the petrochemical, heavy chemical and nuclear industries, to its current wide range of applications in industries, such as fine chemicals, food, pharmaceuticals, software, and cybernetics. It is suggested that the impact of changes arising from industry, new technology and society has driven the chemical engineering discipline to a point where it is now ripe for re‐invention. The effects of rapid industrial, technological and societal change on chemical engineering education are studied against the backdrop of a discipline on the threshold of a significant change. The paper concludes by identifying curriculum development, personal development and life‐long learning as three important factors for educating chemical engineers for a successful future. 相似文献

The environmental and resource crises that confront human life on earth demand changes to the whole socio-economic metabolic system. The changes will affect all aspects of life, including the practice of chemical engineering. The historical association of the profession with the fossil carbon economy means that the expertise that makes up chemical engineering must be re-examined and repurposed urgently if the discipline is to play a full role in the socio-economic transition. In this article, we review the historical development of chemical engineering to identify its unique features and find ways in which it can change to meet the challenge. A pattern of 30-year cycles in the development of the discipline is revealed, showing the way it has built up by incorporating approaches from other disciplines and also developing a unique set of skills and knowledge. Chemical engineering as taught needs to prepare graduates to operate under the kind of social contract embodied in declarations by professional bodies. We propose ways in which the expertise comprising chemical engineering can be applied in the ‘just transition’ to a less unsustainable society, including new approaches to plant and process design and also applications ‘outside the pipe’ to environmental modelling and industrial ecology. The unsustainability crisis results from a history of poor public and private decisions, so examination of the different types of decisions is timely. Specific roles for chemical engineers in deliberative decision processes are identified, including enhanced emphasis on risk and precaution. 相似文献

The design project represents the culmination of a chemical engineering student’s degree, which is intended to enable students to demonstrate technical competency and achieve team-based learning outcomes. Conventionally the design project is taught through face-to-face learning, however recent circumstances around Covid-19 have required engineering degrees to pivot to remote learning and here the outcome of chemical engineering design project taught through remote learning is reported. The class was tasked with designing processes for vitamin B2, B3 or E production, based on teams of 5 students. The structure of the design project consisted of three major assessments tasks around process feasibility and development, unit operation designs and economics, with students required to undertake group as well as individual assessments. The process by which the design project was taught remotely is presented here; in terms of educator-student engagements, promotion of student interaction within teams, online tools and ensure students had access to appropriate software. The outcome was a successful final year design project for chemical engineering students, which achieved comparable performance outcomes to previous years’ face-to-face teaching as well as demonstration that student interactions within teams are vital to a successful outcome. 相似文献
