Abstract
Pinch energy-saving Technology is currently the most valued in practice, it is based on the first and second laws of thermodynamics, does not perform quantitative analysis and calculations, and uses the concept of optimization, but does not require advanced mathematics for optimization technology. This chapter first introduces the process dual subsystem system model, which is divided into the heat exchange subsystem and the process operation subsystem, the heat exchange subsystem includes three parts: cooling, heat exchange, and heating. the pinch energy-saving technology plays the most important role in the heat exchange subsystem; it includes 7 sections: the concept of pinch point and its determination; Pre-estimate the heat exchange network area and the optimal \(\Delta T_{\min }\); Energy target determination; Pinch design of heat exchange network; Placement of the heat engine (pump) in the total energy system; The effect of cross heat transfer on heat exchange network area and energy; Energy saving principle of pinch technology; and in Sect. 13.7 provided the showcase of Pinch analysis examples using Aspen Energy Analyzer.
