Keval Sanket Bhatt

Abstract: This paper presents the design and performance evaluation of a shell and tube heat exchanger using advance simulation tools ? HTRI and Aspen Exchanger Design and Rating (EDR). Heat exchangers are essential to process industries for achieving efficient thermal energy transfer. The objective is to assess and compare the thermal performance, sizing, and optimization capabilities of both tools using a common problem statement involving benzene and water as the working fluids. Key design parameters such as overall heat transfer coefficient, heat transfer area, fluid velocities, and pressure drops were determined using both software platforms. The comparative analysis highlights the advantages and limitations of each, with HTRI offering high - fidelity design accuracy and Aspen EDR providing seamless integration with process simulation environments. This work demonstrates the importance of simulation - driven design in improving heat exchanger efficiency and provides insights into the selection of appropriate design tools in industrial applications.
