Improving the efficiency of the catalytic reforming process and the heat exchanger of the unit
S.M. Asadov PhD in Tech. Sc. - Azerbaijan State University of Oil and IndustryThis study presents a comprehensive investigation aimed at improving the performance of shell-and-tube heat exchangers used in catalytic reforming units. The primary objective is to enhance energy efficiency and operational effectiveness by optimizing heat and mass transfer processes within the apparatus.
A three-dimensional numerical model of the heat exchanger was developed using computational fluid dynamics (CFD) techniques. The simulations were performed in the ANSYS Fluent environment, incorporating heat transfer, flow hydrodynamics, and the distribution of temperature and velocity fields. The proposed computational algorithm is distinguished by its simplicity, robustness, and high accuracy, combining both analytical and numerical approaches.
A four-pass counterflow shell-and-tube heat exchanger configuration was selected for the study. Based on its geometric parameters, a high-resolution computational mesh was generated. The simulation results provided detailed temperature and velocity contours, as well as key operating parameters such as inlet/outlet temperatures, pressure drops, and flow rates. The numerical results were validated against analytical solutions, confirming the reliability of the developed model.
The analysis demonstrates that appropriate selection of geometric parameters and proper flow organization significantly improve the thermal efficiency of the heat exchanger. The results indicate that both hot and cold streams can achieve their target temperatures with minimal energy consumption.
The proposed methodology is versatile and can be applied to the design and optimization of various types of heat exchangers. Overall, the study provides an effective framework for enhancing the performance of heat exchange equipment and improving the energy efficiency of catalytic reforming processes in industrial applications.
