    NH4HS corrosion has been a serious problem in oil refining plants. The corrosion rate dramatically increases over a certain concentration of NH4HS. In high pressure plants such as hydrodesulfurization units which are operating in NH4HS environments, leakage caused by corrosion could result in catastrophic disaster. Therefore, in the design phase, corrosion prevention techniques should be considered. In this study, a new design philosophy to prevent NH4HS corrosion in a sour water environment was successfully developed based on simulation techniques.
