The use of organic amines to neutralize crude tower overhead waters is a common corrosion control practice in refineries. However, their presence in the system can lead to corrosion problems caused by reaction with hydrogen chloride to form corrosive salts. Use of overhead waters as a desalter wash source can aggravate the problem by building up the concentration of amine in the preheat systems, tower and associated product and pumparound systems. Electrolyte-based simulation has provided valuable insight into the vapor-liquid-aqueous partitioning behavior of commonly encountered amines at various conditions.
