In thermo-chemical process industries, Heat Exchanger Network design and retrofit represent an important part of the plant design. The purpose of this network is to maximise heat recovery from process streams entering and exiting process equipment, thereby lowering the overall plant costs. The use of Pinch Technology in design ensures maximum heat recovery and minimum energy consumption resulting in minimum cost of hot and cold utilities. Energy Integration of cement industry was carried out using the principle of Pinch Technology. In present case study, Heat Exchanger Network was designed by use of methodology of Aspen Energy Analyser software V10.0 and Pinch Technology. The optimum minimum approach temperature of 11 °C was used to determine the energy target and the Pinch Point Temperature was found to be 994.5 °C. The utilities targets at Minimum Approach Temperature were found to be 1.594x107 kJ/h and 1.075x108 kJ/h for hot and cold utilities respectively. Pinch Analysis is best energy integration technique, which saves more energy and utilities cost than the traditional energy technique.
