There has been recent interest in the use of hydrogen flux monitoring at high temperatures to evaluate ‘naphthenic acid’ and sulfidic corrosion in high temperature process streams associated with crude distillation units. In this report, we present flux and corrosion data obtained from samples drawn from a refinery process stream.

The depletion of conventional sweet oil resources has led to increased attention towards sour and acidic oil sources, which typically consist of lower-quality, corrosive crude oils with elevated concentrations of naphthenic acids and sulfur compounds. They are often referred to as “opportunity crudes” since they come at a lower price to refiners, but if successfully processed, they can result in a higher margin to the refinery. This paper focuses on an investigation of the impact of active sulfur species present in crude oils during processing. Corrosion rates of several common alloys were evaluated under stirred/pipe flow conditions in autoclaves. The experimental conditions closely simulated relevant refinery environments, encompassing temperatures ranging from 200°C to 370°C. The study assessed the influence of temperature, wall shear stress (WSS), and active sulfur content on corrosion rates. The results were derived from a comprehensive Joint Industry Program (JIP) conducted to quantify the influence of crude oil chemistry on naphthenic acid corrosion, understand the contributions of active sulfur chemistry to protection and FeS scale formation. The program also assessed the ability to resist naphthenic acid corrosion by utilizing beneficial sulfur speciation in the context of operational factors such as temperature and wall shear stress to build a prediction model to characterize the active sulfur level as a function of sulfur compound concentration and temperature, which is further utilized to predict corrosion rates of multiple alloys.

Naphthenic Acid Corrosion And Sulfidic Corrosion In Crude Oil Fractions

Product Number: 51322-17533-SG

In the petroleum industry, much greater attention has been focused on more highly sour and acidic oil resources due to the gradual depletion of conventional sweet oil resources. In addition, reducing crude oil costs have forced to look for opportunity (alternate) crudes, usually low-quality corrosive crude oils with high concentrations of naphthenic acids and sulfur compounds.1 The main constituents in the crude that cause corrosion are sulfur compounds, organic and inorganic chlorides, salt water, organic and inorganic acids. Processing of these highly acidic and sulfur-containing crudes at high temperatures in refineries has promoted significant corrosion problem in hot oil distillation units and associated piping systems.
