Corrosiveness of two separate hydroprocessing units was assessed with a corrosion prediction software tool developed under joint industry sponsorship. The predicted corrosion rates for the piping, using this software tool, were compared with actual field data. The results confirmed the accuracy of the corrosion prediction model incorporated into the software tool, as well as emphasized the need to incorporate both flow modeling and environment variables in the assessment for corrosiveness of alkaline sour water systems. These data and the associated software tool have been successfully used to provide significant economic benefit.
