Corrosion control in oil refining equipment is very complex, as these issues are associated with the ever-changing conditions of a refinery. These changing conditions may include swings in production requirements, increase in unit throughputs, processing of opportunity crudes, legislative changes to product specifications, and the list goes on. In the refinery hydrotreating processes, the reactor effluent system is prone to fouling and corrosion via ammonium bisulfide (NH4HS) and ammonium chloride (NH4CL) deposition. NH4HS salts can lead to reactor effluent air cooler (REAC) tube fouling and plugging, and if an aqueous phase develops, under-deposit corrosion. OLI has developed the simulation technology to model these systems and predict the formation of these corrosive chemicals, allowing refiners to better manage the unit integrity and analyze the process of operating envelopes under changing conditions.
