PSE, process systems engineering, is about the development and application of systematic methods for process studies by the chemical engineer. By means of software tools, the application of these methods is facilitated. Over the last about half a century, CAPE (computer aided process engineering) tools have found their way into process engineering. For example it is unthinkable nowadays to design a plant without a simulation through a process simulator. But there are many more applications of PSE in industry.The aim of this paper is to provide a taste of the meaning of PSE within the industrial R&D environment. The intention is not to provide a complete overview but to give a flavour of what is perceived as the benefits of PSE during process development, and, in which areas PSE should be extended to render further benefits. The combined approach of experiments and modelling offers a very (cost-)effective strategy in industrial R&D. Further improvements are desired in the areas related to process intensification (PI) and (conceptual) product design. It is believed that the current methods would be more beneficial and have a stronger applicability in industry by inclusion of semi-predictive models and uncertainty considerations. 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

Water is used intensively by various sectors such as agriculture, industry, and the public. Increasing global water demand and the effects of climate change are leading to overuse of water resources in many regions. One strategy to meet these challenges is to implement an integrated industrial water management, e.g., by water reuse or the use of alternative water resources. The development of new concepts and technical, digital, and nontechnical innovations together with priorities will continue to set the course for future integrated water management, particularly in the industrial environment. 相似文献

The ever-increasing quest to identify, secure, access, and operate oil and gas fields is continuously expanding to the far corners of the planet, facing extreme conditions toward exploring, securing, and deriving maximum fluid benefits from established and unconventional fossil fuel sources alike: to this end, the unprecedented geological, climatic, technical, and operational challenges have necessitated the development of revolutionary drilling and production methods. This review paper focuses on a technological field of great importance and formidable technical complexity—that of well drilling for fossil fuel production. A vastly expanding body of literature addresses design and operation problems with remarkable success: what is even more interesting is that many recent contributions rely on multidisciplinary approaches and reusable Process Systems Engineering (PSE) methodologies—a drastic departure from ad hoc/one-use tools and methods of the past. The specific goals of this review are to first review the state-of-art in active fields within drilling engineering and explore currently pressing technical problems, which are in dire need or have recently found, PSE- and/or computational fluid dynamics-relevant solutions. Then, we illustrate the methodological versatility of novel PSE-based approaches for optimization and control, with an emphasis on contemporary problems. Finally, we highlight current challenges and opportunities for truly innovative research contributions, which require the combination of best-in-class methodological and software elements in order to deliver applicable solutions of industrial importance. 相似文献

The design of pulsed sieve‐plate extraction columns (PSE) on the basis of published data is not currently possible as it relais on additional and cost intensive laboratory experiments. This is due to the lack of knowledge about the complex mass transfer between two liquid phases which is strongly influenced by factors such as surface active impurities and the Marangoni‐effect. In order to reduce the experimental effort in the determination of the required design input data, several standard experimental test units have been developed at the Institut für Thermische Verfahrenstechnik that allow the determination of the needed fluiddynamic and mass transfer data. The test units are based on single drop experiments, and they use the technical mixture to be separated in practice. Finally, the meas ured mass transfer and fluiddynamic data are used to calculate the drop‐size‐, holdup‐ and concentration‐profiles for the systems toluene‐ace tone‐water and n‐butylacetate‐ace tone‐water in a PSE‐column and a spray‐column. The results are compared with experimental data reported in the literature and our own data obtained with a semi‐industrial PSE‐column. 相似文献

The significance of biotechnology for industrial chemistry. In the next few decades biotechnology will bring about fundamental innovations in the fields of health, nutrition, and agriculture as well as in important branches of industrial production, such as chemistry, which may well be comparable in importance with the present revolutionary technical progress based on electronics. Justification for these forecasts comes mainly from pioneering scientific advances in the fields of molecular biology, biochemistry, and microbiology. Particular mention should be made here of the fascinating potential of genetic engineering methods presently undergoing rapid development. However, less spectacular techniques, such as cell fusion and the immobilization of enzymes or whole living cells on polymeric substrates to give manageable, long-lived biocatalysts, will also contribute to this wave of innovation. Some of these new developments are now gaining acceptance in industrial production. 相似文献
