Sulfur species in crude oil

S-containing compounds and then a heavy crude oil, and only sulfur-containing compounds were selectively alkylated. The deuterium labeled alkylating reagents, iodomethane-d3 (CD3I) and iodoethane-d5 (C2D5I), were employed to the alkylation of heavy crude oil to selectively differentiate the tagged sulfur species from the original crude oil. The amount of total sulfur in a crude oil depends on the type of oil field and it varies from 0.05% to 14%. Of course, sulfur values as low as 0.2% are enough to create sulfidation corrosion in plain steels and low alloy steels. These kinds of steels are often used in several parts of refinery units.

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 “AUTODEST-800” according to ASTM 2892. oil desulfurization specifically. Sulfur in crude oil Sulfur is the most abundant element in petroleum after carbon and hydrogen. The average sulfur content varies from 0.03 to 7.89 mass% in crude oil (Mehran et al. 2007). The sulfur compounds can be found in two forms: inor-ganic and organic. Inorganic sulfur, such as elemental sulfur, H It was reported that BDS by Pantoea agglomerans D23W3 resulted in 61% sulfur removal from a light crude oil that originally contained 0.4% sulfur and 63% sulfur removal from a heavy crude oil that originally contained 1.9% sulfur. It was found that integrated methods performed better than just BDS. • SulphCo was founded in 1999 as an energy technology company focused on the development and commercialization of an oxidative desulfurization (“ODS”) process for liquid petroleum streams including crude oil products, crude oils, natural gasoline and condensate streams.

The main objective of this study is to develop a methodology for sulfur compounds speciation using two-dimensional gas chromatography coupled with a flame

Intertek laboratories detect and trace level measure sulfur species in petroleum, petroleum-refined products such as fuels and petrochemicals, natural gas, and polymers. Sulfur (sulphur) species components are characterized and detectable to ultra-trace levels. Using the sulfur content, crude oils can be classified as sweet (<0.5%wt S) and sour (>0.5% %wt S). The distillation process segregates sulfur species in higher concentrations into the higher-boiling fractions and distillation residua. Removing sulfur from petroleum products is one of the most important processes in a refinery to produce fuels compliant with environmental regulations. Nitrogen Content Intertek petroleum laboratories identify and quantify sulfur compounds in crude oil, petroleum feedstocks, and refined petroleum products. Sulfur compounds occur in various types and quantities in hydrocarbon feedstocks and refined products, including gasoline, diesel and many other fuels and materials.
