Summary: Review comments by two top process engineering experts:
Review: Please see the latest (January, 2000) review comments by the following two industrial practitioners:(1)George E. Keller, senior corporate research fellow (retired), Union Carbide Corporation, member of the National Academy of Engineering. (2)Paul F. Bryan, Research Scientist (retired), Union Carbide Corporation; Station Director of the MIT Chemical Engineering Practice School, Mt. Vernon. George E. Keller and Paul. F. Bryan,"Process Engineering Moving in New Directions", Chemical Engineering Progress, pp. 41-50, January issue (2000). They wrote: "An extremely important aspect of process design for overall waste minimization is water reuse and wastewater minimization. A new book, Mann and Liu (1999),covers this area very well, and gives many industrial examples. It includes recent work on the water-pinch technology (which is akin to heat-exchanger network technology) for determining the absolute minimum amount of fresh-water makeup to a process. Application of the methods described in this book potentially can cut both the overall investment and operating cost of a process, as well as reduce fresh-water usage. In the future, the approach described here should become a key element in any comprehensive process-design effort".
