The considerable amount of energy used in industrial processes is typically used for heating and cooling. The synthesis of heat ex-changer networks (HEN) is a critical topic in this industry in order to reduce energy and capital costs in chemical plants. Heating and cooling systems in industry must be designed efficiently, which can be done using technologies like pinch analysis to create an optimal heat recovery network. Heat pinch analysis is a systematic method for designing thermally efficient systems. A designer can determine the minimum heating and cooling requirements as well as the maximum heat recovery (MHR) potential by locating a thermodynamic bottleneck, or the pinch point for heat recovery. This Paper uses Aspen Energy Analyzer for HEN Design.Heat integration network design is a cost-effective strategy that helps industries to cut costs by reducing the number of external utilities needed and increase profitability by lowering energy consumption. The HENs’ composite curves, grand composite curves, grid representation, and target reports were created using the Aspen Energy Analyzer. The software suggested ten designs, which were then optimized based on total annualized cost. By comparing it to other optimized designs, the best design is determined.
