A HEN will involve the four process streams and two utilities shown above. A minimum approach of 30°C will be used for design purposes. Set up the problem table for the network and use it to determine the hot and cold stream temperatures at the pinch and the minimum-utility targets for the system. Ans. 150°C, 120°C, 475 kW (hot), 455 kW (old)
