Process systems engineers material selection

The corrosion engineer can play a major role in system design, material selection, process or environmental control, and remediation. The focus of these efforts should not necessarily be the complete elimination or avoidance of corrosion, but rather the selection of the most cost-effective means of corrosion control and abatement. 

Since life cycle assessment (LCA) can be more than an environmental impact assessment approach, chapter Life Cycle Sustainabiftty Assessment A Holistic Evaluation of Social, Economic, and Environmental Impacts discusses life cycle sustainabiftty assessment. This extends the holistic environmental LCA to account for the economic and social pillars of sustainabiftty. Lastly, chapter Embedding Sustainabiftty in Product and Process Development—The Role of Process Systems Engineers describes the practical role of process systems engineers in the implementation of sustainabiftty in product and process development. It shows some key aspects and tools that practitioners should take into account to design and develop more sustainable products and processes during material selection, process design, process and product modeling, and supply chain implications. 

The CRC-Elsevier materials selector , 2nd edition, N.A. Waterman, and M.E Ashby CRC Press (1996) ISBN 0412615509. (Now, also available on CD-ROM). Basic reference work. Three-volume compilation of data for all materials includes selection and design guide. The Materials Selector is the most comprehensive and up-to-date comparative information system on engineering materials and related methods of component manufacture. It contains information on the properties, performance and processability of metals, plastics, ceramics, composites, surface treatments and the characteristics and comparative economics of the manufacturing routes which convert these materials into engineering components and products. 

In addition, the Material Engineering Center at Dow Plastics offers its PAMS (Processes and Materials Selection) system on the Internet to help designers match material and fabrication requirements with product and economic requirements (www. plasticsnot.com/moc). 

CBR systems is presented in Fig. 12. The first, "M-BASE," facilitates the process of retrieving materials according to a given set of desired properties and/or specifications. The second, "C-BASE, helps the materials engineer in the difficult task of selecting materials for corrosion resistance in complex chemical environments.
