Crude oils containing naphthenic acids can cause a variety of corrosion problems in any of several process areas. But because of the complexity of naphthenic acid corrosion, no routine technique is available for predicting corrosion from this source. Certain high-temperature corrosion inhibitors with a general phosphate ester structure have shown good mitigation of naphthenic acid corrosion in commercial applications. A description of two such cases will help refiners know what to look for to prevent similar occurrences in their plants.
