DESCRIPTION The goal of this book is to help the student experience chemical engineering to the fullest extent possible within the constraints of limited time and limited student background. In pursuit of that goal, it teaches the freshman to solve quantitative problems, although at a low level of complexity and within a scope that is narrow and well-defined. These quantitative topics include material balances (reacting and non-reacting systems), fluid flow (including the sizing of pumps), mass transfer (diffusion and convection), chemical reactor design, heat transfer (including the design of heat exchangers), and engineering economics. As examples of the limited scope of these topics, the treatment of material balances for reacting systems is limited to single process units with one chemical reaction, and the treatment of fluid flow applications is restricted to the use of the mechanical energy balance where friction is mentioned, but friction factors and methods for determining friction losses are not introduced. Spreadsheets are also taught, and homework problems throughout the book give the students practice with this tool. In addition, a number of qualitative descriptions are presented in the text, including chapters on problem solving, engineering teamwork, and process control. Finally, the students are given a few writing assignments to illustrate the important role of written communication in engineering.
Chemical Product Design
The chemical industry is changing, going beyond commodity chemicals to a palette of higher value added products. This groundbreaking book, now revised and expanded, documents this change and shows how to meet the challenges implied. Presenting a four-step design process – needs, ideas, selection, manufacture – the authors supply readers with a simple design template that can be applied to a wide variety of products. Four new chapters on commodities, devices, molecules/drugs and microstructures show how this template can be applied to products including oxygen for emphysema patients, pharmaceuticals like taxol, dietary supplements like lutein, and beverages which are more satisfying. For different groups of products the authors supply both strategies for design and summaries of relevant science. Economic analysis is expanded, emphasizing the importance of speed-to-market, selling ideas to investors and an expectation of limited time in the market. Extra examples, homework problems and a solutions manual are available.
