Chemical Reaction Route Selection Based on Green Chemical Engineering   总被引:1,自引:0,他引:1  
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, IRoute is proposed to determine the suitability of a chemical route in this paper. IRoute 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

Biology is a rich source of great ideas that can inspire us to find successful ways to solve the challenging problems in engineering practices including those in the chemical industry. Bio-inspired chemical engineering(Bio Ch E)may be recognized as a significant branch of chemical engineering. It may consist of, but not limited to, the following three aspects: 1) Chemical engineering principles and unit operations in biological systems; 2) Process engineering principles for producing existing or developing new chemical products through living ‘devices';and 3) Chemical engineering processes and equipment that are designed and constructed through mimicking(does not have to reproduce one hundred percent) the biological systems including their physical–chemical and mechanical structures to deliver uniquely beneficial performances. This may also include the bio-inspired sensors for process monitoring. In this paper, the above aspects are defined and discussed which establishes the scope of BioChE.  相似文献

在我国市场经济的不断完善的新形势下,对项目建设的规范化要求也越来越高,加强化工工程项目建设的进度管理已成为市场经济的需求。计划管理是以现代科学方法确定进度目标,通过把工期目标和任务层层分解,编制合理的进度计划与资源供应计划进行进度控制,在与其它目标相协调的基础上实现工期目标。针对化工工程项目存在的问题从组织机构、技术、质量、安全、生产资源等方面制定了保证措施,通过应用WBS对项目进行细化和分解,制定进度计划,确定影响项目进度的关键路径,并进行重点控制。  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
