Technology Overview Crude unit fractionators are susceptible to ammonium chloride and amine hydrochloride salt formation, especially when running lower overhead temperatures or operating with a cold reflux or pumparound return. When these chloride salts form, they result in severe corrosion and fouling from salts and corrosion products formed in the tower, compromising unit reliability and profitability.
