Study on the Failure of Heat Exchanger Tubes in the Chemical Industry
- 1 Babeș-Bolyai University, Cluj-Napoca, Romania
Abstract
In the chemical industry, heat exchangers play a critical role in maintaining process efficiency. However, these systems are prone to frequent failures, often necessitating extensive maintenance or repairs, which in turn adversely affect the overall economic performance of industrial operations. The chemical industry commonly operates in highly corrosive environments, making corrosion the predominant failure mechanism for heat exchangers. Key factors contributing to corrosion-related failures include defects in fabrication and welding, suboptimal material selection, improper water flow or chemistry management, and the presence of corrosive species in water. This study investigates the corrosion behaviour of heat exchangers under various corrosive conditions, utilizing COMSOL Multiphysics for simulation and analysis.
