Study on Simulation for Erosion-Corrosion in Petrochemical Process Piping

Abstract Erosion-corrosion is a damage to metal caused by relative motion at high velocity between metal surface and erosive/corrosive fluid, resulting from combined actions by mechanical erosion and electrochemical corrosion. Since petrochemical plants install numerous process pipes, especially involving complex oil refining processes and multi-phase transformation between solid, liquid and gas, the erosion-corrosion becomes one of major problems that disturb industrial work safety. So, it is important to create a mechanistic simulation model by fully considering various factors and closely simulating erosion-corrosion process.
