Abstract
The failure of the E-637 heat exchanger necessitated repairs and prompted a redesign process. Initially, the non-circular, thick-walled vessel was designed using elasticity theory and evaluated against established standards. Data for analysis and redesign were gathered from the E-637 heat exchanger at the Shazand Oil Refinery. Both analytical and numerical modeling were conducted in accordance with standard requirements and incorporated reasonable simplifications. The simulation results were compared with operational data, which confirmed the accuracy of the analysis and design process.After verifying the design's accuracy, the optimization process commenced. The final model was analyzed based on the actual configuration while considering theoretical thicknesses. Studies showed that the ASME approach tends to adopt a conservative design. Therefore, optimization was achieved through numerical simulations and adherence to standard guidelines. This process led to a reduction in the vessel wall thickness. Ultimately, by referencing the analyses in Chapter 5 of the standard, the initial thicknesses were successfully optimized.
