What is the principle of thermal-stable salt corrosion of N-methyldiethanolamine (MDEA)?
Reply #22022-01-08
The MDEA solution contains H2S and CO2, which facilitates electrochemical corrosion on the metal surface and reduces the service life of the storage tank.

The corrosion mechanism is complex, including the high-temperature thermal degradation and oxidative deterioration of MDEA; in the presence of H2S, it forms a stable salt called HSS by combining with the corrosive agents

Under different operating conditions, the corrosion mechanisms vary. Your conditions aren’t specific; how can the results be specific then?
