Carbon-Dioxide Corrosion in Stainless Steel (304L) Pipes

This research comprehensively addresses challenges associated with carbon dioxide (CO2) corrosion in 304L stainless steel pipes, particularly under high temperatures and elevated CO2 partial pressures. Utilizing advanced simulation techniques with COMSOL Multiphysics, the corrosion behavior of 304L stainless steel is systematically investigated. Critical factors influencing corrosion rates, including operating temperature, reference temperature, initial electrolyte potential, and CO2 partial pressure, are identified. The study proposes practical mitigation strategies, such as employing more resistant materials like duplex stainless steel and applying protective coatings on inner pipe surfaces. The second study focuses on simulating and analyzing CO2 corrosion in 304L stainless steel pipes, aiming to address research gaps. The results facilitate the design and operation of systems utilizing 304L stainless steel in CO2 environments more effectively. Implementing measures to reduce PCO2 can diminish the corrosion rate, extending the system's lifespan.
