Temperature and Velocity Effects in Naphthenic Acid Corrosion

Abstract

Abstract The effects of temperature and velocity were studied with respect to alloy selection for corrosion resistant service. The amount of molybdenum in the austenitic stainless steel alloys is critical in conferring corrosion resistance on the alloy as the temperature of the environment increases. Velocity effects have been studied in a closed loop hot oil circuit where the stream impinges on the target specimen. Film breakdown is prevented by increasing the molybdenum content.
