Refiners often consider increasing theamount of sour or high total acid number
(TAN) crude processed to improve the
refinery’s profitability. Typically, as sulfur
levels increase, the risk of sulfur corrosion
on low chrome steels increases within the
crude unit. And, as crude oil TAN levels
are increased, the risk profile for hightemperature
naphthenic acid corrosion
increases within the crude unit. Higher
amounts of naphthenic acids can lead to
higher rates of corrosion in the desalted
crude oil, diesel, gas oil, and bottoms
circuits—negatively impacting unit reliability
and performance. smartguard-slsh.pdf
