First published by the Institution of Chemical Engineers as the User Guide on Process Integration for the Efficient Use of Energy, this is the original guide for professionals and students on understanding and using pinch analysis and process integration. These are the key techniques used by chemical engineers and process industry professionals to minimise energy waste and optimize the efficiency of any process. It is an indispensable working reference for all engineers. Rigorous, practical, supported by multi-stream process analysis software on CD and detailed illustrative case studies throughout, this thorough revision enables engineers to maximise energy efficiency in their own plant, whether for new design or for the retrofitting of an existing system. THE original pinch analysis and process integration guide, fully revised and supported by CD with multi-stream process analysis software The only dedicated reference for chemical process, food and biochemical consumer products industries and beyond Covers the practical analysis of new and retrofitting of existing systems for energy efficiency maximization
