Manufacture of tubular components by pressure-assisted injection forging has several advantages over other manufacturing processes. The research conducted previously demonstrates the feasibility of using the process to produce thick-walled tubular engineering components. To improve process-analysis efficiency and to promote engineering applications of the process, an analytical algorithm was developed on the basis of a study of the mechanics of the process. Compared with forming experiments and finite element (FE) simulations, the applied-force and stress requirements calculated using the algorithm are sufficiently accurate. Using the analytical algorithm and FE analysis procedure developed, predominant force and stress components of the process were analysed, which resulted in details of the process mechanics. This is useful information for future uses in process design and optimization.

This paper describes the state of the art and future opportunities for process design and sustainable development. In the Introduction, the main global megatrends and the European Union’s response to two of them, the European Green Deal, are presented. The organization of professionals in the field, their conferences, and their publications support the two topics. A brief analysis of the published documents in the two most popular databases shows that the environmental dimension predominates, followed by the economic one, while the social pillar of sustainable development is undervalued. The main design tools for sustainability are described. As an important practical case, the European chemical and process industries are analyzed, and their achievements in sustainable development are highlighted; in particular, their strategies are presented in more detail. The conclusions cover the most urgent future development areas of (i) process industries and carbon capture with utilization or storage; (ii) process analysis, simulation, synthesis, and optimization tools, and (iii) zero waste, circular economy, and resource efficiency. While these developments are essential, more profound changes will be needed in the coming decades, such as shifting away from growth with changes in habits, lifestyles, and business models. Lifelong education for sustainable development will play a very important role in the growth of democracy and happiness instead of consumerism and neoliberalism.

This review paper describes some historical facts, the state of the art of process design and sustainable development. In the Introduction the most important global megatrends are presented and the European Union response to them, the European Green Deal. Process design and sustainable development are dealt with separately and holistically. Organization of professionals from the area, their conferences and publication are supporting the two topics. A short analysis of the published documents in two most popular databases shows that environmental dimension is prevailing, followed by economic one while social pillar of sustainable development is undervalued. The most important design tools for sustainability are described. An important practical case, the European chemical and process industries are analyzed and their achievements in sustainable development are shown; in particular their strategies are presented in more detail. The conclusions are embracing the most urgent future development areas of process industries, carbon capture with utilization or storage, the process analysis, simulation, synthesis and optimization tools; zero waste, circular economy and resource efficiency are already playing an important role. But deeper changes are needed in the future decades including de-growth with changes of habits, lifestyles, and business models. Lifelong education for sustainable development will play a very important role in the growth of democracy and happiness instead of the consumerism and neoliberalism.

Good Agreement

During casting process design, CAD/CAE technology can play important role to avoid macroscopic irregularity, internal defect and assure casting performance. Based on the casting process analysis and gating system design, the numerical simulation of gray iron butterfly valve was done by hydrodynamic software Flow-3D to obtain its optimal process scheme. According to the simulation results including flow field, temperature field and defect distribution, the merits and faults of designed schemes were investigated and then the feasible gating system was proposed. The results showed that, compared with top or intermediate casting, when adopting bottom casting, steady flow of molten metal and reasonable temperature distribution could be achieved. And workpiece defects mainly distributed in riser. The predicted results are in good agreement with practical ones.

Single Batch

This chapter teaches students and practicing engineers the fundamentals of bioprocess design with an emphasis on bioseparation processes. It combines the information presented in earlier chapters for use in the context of integrated processes. The ultimate objective is to enable the reader to efficiently synthesize and evaluate integrated bioseparation processes. Given a product and a desired annual production rate (process throughput), bioprocess design endeavors to answer the following and other related questions: What are the required amounts of raw materials and utilities needed for a single batch? What is the total amount of resources consumed per year? What is the required size of process equipment and supporting utilities? Can the product be produced in an existing facility or is a new plant required? What is the total capital investment? What is the manufacturing cost? What is the optimum batch size? How long does a single batch take? How much product can be generated per year? Which process steps or resources constitute scheduling and throughput bottlenecks? What changes can increase throughput? What is the environmental impact of the process (i.e., amount and type of waste materials)? Which design is the “best” among several plausible alternatives? After completing this chapter, the reader should be able to do the following: • Initiate a process design and choose the appropriate sequencing of processing steps. • Set up a process flowsheet using the unit procedure concept. • Become familiar with batch process simulators. • Schedule batch processes. • Estimate capital and operating costs. • Perform profitability analysis. • Assess the environmental impact of a process. • Perform process sensitivity analyses. Process design is the conceptual work done prior to building, expanding, or retrofitting a process plant. It consists of two main activities, process synthesis and process analysis. Process synthesis is the selection and arrangement of a set of unit operations (process steps) capable of producing the desired product at an acceptable cost and quality. Process analysis is the evaluation and comparison of different process synthesis solutions.
