Web1 Introduction. Heat integration and the optimization of heat exchanger networks (HEN) is an important domain in chemical engineering and process synthesis. It includes three major steps: 1) minimization of external utility demand, 2) minimization of heat exchanger (HEX) area and 3) minimization of the HEX matches (Yee and Grossmann, 1990 ). Web28 de ago. de 2024 · What is happening is that as fluid enters the heat exchanger there is a 100° difference between the two, so they cool at a high rate. However, as the temperature differential drops, the speed at which heat exchanges also drops. This results in a temperature graph that looks more like this: WebOver a time period of heat exchanger operation the surface of the heat exchanger may be coated by the various deposits present in the flow system. Moreover, ...
