HEAT EXCHANGER NETWORK SYNTHESIS AND OPTIMIZATION BY PINCH ANALYSIS AND DIFFERENTIAL EVOLUTION METHOD

Saving energy and carbon emission are the major issues in present societies. Heat integration plays an important role in process plants to improve energy conservation, prevent emissions and reduce the capital and operating costs. In heat exchanger network (HEN) the cold streams and hot streams are connected in proper way to maximize heat recovery and reduce the energy consumption. Heat exchanger network synthesis (HENS) and optimization is a comprehensive method to design the network of heat exchangers for efficient heat conservation by cost-effective manner. It improves and optimizes the recycling energy and the heat exchange between hot andcold streams to reduce the heating and cooling utility. During the last four decades, different methods and tools have been applied to design HENs to improve the energy conservation, decrease the gas emissions and minimize the cost of the process
