Naphthenic acids and sulfur compounds present in crude oils may cause corrosion in oil
refineries. In some cases, corrosion product scale formed in these oils may provide …

Naphthenic acid (NAP) corrosion is a major concern for refineries. The complexity of NAP in
crude oil and the sulfidation process hinder a fundamental knowledge of their corrosive …

In crude oil refineries, high temperature corrosion in nonaqueous phase, predominantly by
carboxylic acids (also known as naphthenic acids in crude oil) and sulfidation, is an old …

Naphthenic acid corrosion of steel is a major challenge in oil refineries. Iron sulfide scales,
formed by corrosion due to sulfur compounds found in the crude oil, have shown …

Corrosion control at refineries remains a challenge because the mechanism of naphthenic
acid (NAP) corrosion is still not fully understood. The rate of NAP corrosion does not …

Corrosion by naphthenic acids and sulfur compounds is a major concern for crude oil
refineries. Corrosion rates in both field and laboratory studies demonstrate corrosion product …

Naphthenic acid (NAP) and reactive sulfur (RS) species present in crude oils pose serious
corrosion problems in oil refineries, especially with the increase in processing of low-quality …

Identification of the layout of phases produced on silicon-containing steel exposed to heavy
cuts of crude oil during high temperature refining service provides an indication of the …

Because the rate of naphthenic acid corrosion does not correlate with the concentration of
acids, it has been proposed that a subset of naphthenic acids in petroleum fractions may be …

Cheap heavy crudes become attractive for oil refineries to increase their benefit margins but
the corrosivity of heavy crudes compels the refinery engineers to blend them with the more …
