Abstract
The heat exchanger is the main industrial equipment used for heat transfer between two fluids. Due to its wide use and importance, the present work aims at the modelling and optimization of a shell and tube heat exchanger by the Gray Wolf Optimization (GWO) method. Three cases were analyzed: 1) methanol-water, 2) kerosene-crude oil and 3) distillated water-raw water. The optimized variables were the shell’s internal diameter, the tube’s external diameter and the baffle’s spacing, in order to reduce the exchanger’s initial investment and operational cost. The classic GWO and a modified version were used, in which parameters within the code varied by exponential, gaussian and beta functions. Case 3 exchanger was also simulated in software Chemcad® in order to compare with some of the modelling’s values and fully design the equipment. The results obtained by the classic GWO were superior than the modified code, with costs reduction of 13.4 and 46.34% for the first and third cases, respectively. The second exchanger had its total cost increased. The simulation in Chemcad® was performed successfully, with great agreement between the thermal and hydraulic coefficients. The equipment was fully designed, having the remaining physical parameters and its type defined.
