This paper summarizes corrosion experience in crude distillation units processing highly naphthenic California crude oils. Correlations have been developed relating corrosion rates to temperature and total acid number. There is a threshold acid number in the range of 1.5 to 2 mg KOH/g below which corrosion is minimal. High concentrations of hydrogen sulfide may raise this threshold value.
