绿色过程系统工程进展 总被引:8,自引:0,他引:8
介绍了由于可持续发展的要求、绿色壁垒的出现及企业形象认证等因素促使绿色过程系统工程作为一门学科分枝应运而生。与传统过程系统工程集中研究人为系统而把环境要求作为约束条件不同,绿色过程系统工程强调过程系统和自然系统之间关系,目的在于把人为系统放回到自然系统中去以形成经济一技术一社会和谐发展的统一体。评述了近20年来在该领域的工作进展。提出了绿色过程系统应成为一门大学教育课程。 相似文献

This is an overview of the development of process systems engineering (PSE) in a smaller world. Two different spatio-temporal scopes are identified for microscale and nanoscale process systems. The features and challenges for each scale are reviewed, and different methodologies used by them discussed. Comparison of these two new areas with traditional process systems engineering is described. If microscale PSE could be considered as an extension of traditional PSE, nanoscale PSE should be accepted as a new discipline which has looser connection with the extant core of chemical engineering. Since "molecular factories" is the next frontier of processing scale, nanoscale PSE will be the new theory to handle the design, simulation and operation of those active processing systems. 相似文献

Biotechnology has many applications in health care, agriculture, industry and the environment. By using renewable raw materials, biotechnology contributes to lowering greenhouse gas emissions and moving away from a petro‐based towards a circular sustainable economy. However, major developments are still needed to make industrial biotechnology an economic alternative to conventional processes for fuels, specialty and/or bulk chemicals production. Process integration is a holistic approach to process design, which emphasizes the unity of the process and considers the interactions between different unit operations from the outset, rather than optimizing them separately. Furthermore, it also involves the substitution of two or more unit operations by one single novel unit capable of achieving the same process goal. Conversely, process systems engineering (PSE) deals with the analysis, design, optimization, operation and control of complex process systems, as well as the development of model‐based methods and tools that allow the systematic development of processes and products across a wide range of systems involving physical and chemical change. Mature tools and applications are available for chemical technology and steps have been taken to apply PSE principles also to bioprocess technology. This perspective paper argues that an interdisciplinary approach is needed towards integrated bio‐processing in order to link basic developments in biosciences with possible industrial applications. PSE can foster the application of existing and the development of new methods and tools for bioprocess integration that could promote the sustainable production of bio‐/chemical products. The inclusion of PSE principles and methods in biochemical engineering curricula and research is essential to achieve such goals. © 2014 Society of Chemical Industry 相似文献

This work presents a technical possibility to produce PSE (particle stabilized emulsions, so called Pickering emulsions) using inorganic nano-particles, which can be highly abrasive. The influence of process parameters (such as inlet flow combination, volume throughput, pressure) and special challenges arising from using nano-particles instead of emulsifier molecules are depicted. Furthermore, the stability and droplet size distributions of oil-in-water (o/w) emulsions stabilized with x~200 and 12 nm Stober silica particles are discussed. Results are compared to those obtained by batch processing using a rotor–stator-system. Process economics as well as efficiency will also be discussed. 相似文献

This paper reviews the research and development of process system engineering (PSE) in the wastewater treatment process (WWTP). A diverse range of PSE applications have evolved in the wastewater treatment process, such as modeling, control, estimation,
expert system, fault detection and monitoring system. This article describes several types of PSE that have proven to be effective
in WWTP. The merits and shortcoming of PSE and its detailed applications are presented. Since its development is the forefront
in WWTP, a reasonable review of the research progress in this field is addressed. 相似文献
