Design process scope

Process development and process design engineers involved in process scoping, development, and design activities. 

Finally, QA is the effort taken to ensure compliance with government regulations for the systems, facilities, and personnel involved with manufacturing products. Quality assurance audits will be quite varied in scope to achieve this assurance. These responsibilities include batch record reviews, critiques of product design, process validation activity, and, possibly audits of other departments operations. 

It is out of the scope of this book to demonstrate practical case histories for the application of molecular descriptors in the drug design process but we have had some very promising preliminary results. 

Figure 1.9 shows different kinds of flowsheets which mark the start and the end of the part of the overall design process which is covered by the case study. At the beginning, the chemical process is described by an abstract flowsheet which decomposes the process into basic steps without considering the equipment to be used (upper part of Fig. 1.9). The process consists of three steps reaction of caprolactam and water, separation of input substances which are fed back into the reaction, and compounding, which manipulates the polymer produced in the reaction step such that the end product meets the requirements. The lower part of Fig. 1.9 shows a process flowsheet which consists of chemical devices and therefore describes the chemical plant to be built - still at a fairly high level of abstraction. The process flowsheet serves as input for detail engineering, which is beyond the scope of the case study.

Within the scope of this work, the initial spray breakup process, providing information about the dense spray core, will be investigated. The formation of fuel drops will be simulated based on first-principles and will offer detailed insight into primary atomization. The three-dimensional, transient calculation will track the interface evolution through droplet formation and breakup. Because the results will be based on conservation laws, they will be extremely general. This will lead to better models that can be used with confidence in the engine design process.

The confidence acquired by this development has caused TR to review its conception of the scope of hydrometallurgy for lead processing. It is no longer the aim to promote the best hydrometallurgical process and evaluate it against conventional standards, but to design processes that take best account of the constraints within which users operate. The emergence of this confidence can be seen in the chapters that follow.

For comparison of the roughness characteristics of all mentioned nanorough optical surfaces the corresponding Master-PSD curves are shown in Fig. 19. It is obvious that the typical shape of the thin film PSDs can be well approximated by ABC model functions within the scope of the design process (Fig. 5, left). 

In a collaborative design process, product models need to be disseminated in a broad scope. As they are the most important assets of product development companies, so companies are usually reluctant to share these models directly to avoid the leakage of the commercial secrets to competitors. This concern makes it difficult to realize the full potential and benefits of collaboration (see Chap. 18).
