Sulfur-containing crude oil
Sour crude oil is crude oil containing a high amount of the impurity sulfur. It is common to find crude oil containing some impurities. When the total sulfur level in J Sep Sci. 2004 Jun;27(9):691-8. Analysis of sulfur-containing compounds in crude oils by comprehensive two-dimensional gas chromatography with sulfur reactions of sulfur-containing crude oils and explain, in part at least, the large evolution of hydrogen sulfide often observed at temperatures in the vicin-. Hua et al. (2004) found more than 3,500 different sulphur compound in a crude oil, namely thiols, thioethers, disulphides, thiophene derivatives and
In the present work we have studied the distribution of different kinds of sulfur compounds present in light and middle distillates of Kuwait crude oil. A representative sample of Kuwait crude oil was fractionated into naphtha (15-160°C) and 10-15°C cuts in the gas oil boiling range (210-340°C) using an 80L capacity autodistillation unit
Sulfur content is usually measured in weight percentage (wt %) or in parts per million by weight (ppm wt). Crude oil containing less than 0.5 wt % of sulfur is The sulfur contents of target sulfur compounds and their groups in 4 crude oil fractions were also determined. The recoveries for standard sulfur-containing compounds were in the range of 90-102%. The majority of the sulfur in crude oil occurs bonded to carbon atoms, with a small amount occurring as elemental sulfur in solution and as hydrogen sulfide gas. Sour oil can be toxic and corrosive, especially when the oil contains higher levels of hydrogen sulfide, which is a breathing hazard. Sulfur content of crude oils is the second most important property of crude oils next to API gravity. Sulfur content is expressed as weight percent of sulfur in oil and typically varies in the range from 0.1 to 5.0%wt. The standard methods that are use to measure the sulfur content are ASTM D129, D1552, and D2622, depending on the sulfur level.

The standard methods that are use to measure the sulfur content are ASTM D129, D1552, and D2622, depending on the sulfur level. Crude oil containing less than 0.5 wt % of sulfur is considered to have low sulfur content and is known as 'sweet crude oil'. Higher sulfur content than 0.5 wt % results in crude oil being known as 'sour crude oil'. Most of this sulfur content in crude oil occurs in molecular form attache to the hydrocarbons.
Corrosion of Steel at High Temperature in Naphthenic Acid and Sulfur Containing Crude Oil Fractions Increasing oil prices and limited availability of light sweet crudes on oil markets sparked a new interest for oil companies in heavy crude oils in spite of the disadvantages of processing such oils.
The nonpolar sulfur-containing compounds (S 1, S 2 and S 1 O 1 species) can be selectively detected by ESI(+) and differentiated by the C 2 D 5-group from the original crude oil. In comparison with the methylation procedure, a small difference in S 1 O 1 class (2.5%) distribution appears which could result from different reactivities of the Abstract. Naphthenic acids and sulfur containing compounds in crude oils are corrosive at high temperature and have been strong concerns for potential corrosion damage in the atmospheric distillation units, vacuum distillation units, transfer lines, and side cut piping in the refining industry.

Selective Analysis of Sulfur-Containing Species in a Heavy Crude Oil by Deuterium Labeling Reactions and Ultrahigh Resolution Mass Spectrometry. In the present work we have studied the distribution of different kinds of sulfur compounds present in light and middle distillates of Kuwait crude oil. A representative sample of Kuwait crude oil was fractionated into naphtha (15-160°C) and 10-15°C cuts in the gas oil boiling range (210-340°C) using an 80L capacity autodistillation unit Sweet vs. Sour Crude Oil. Sweet. The terms sweet and sour are a reference to the sulfur content of crude oil. Early prospectors would taste oil to determine its quality, with low sulfur oil actually tasting sweet. Crude is currently considered sweet if it contains less than 0.5% sulfur.
