Crude Corrosivity

This training provides a comprehensive overview of naphthenic acid corrosion and high-temperature sulfidation, sometimes described as crude corrosivity. It addresses the fundamental characteristics of these damage mechanisms, with emphasis on the influence of process conditions, material selection, inspection, and monitoring practices.
