Desulfurization of high sulfur petroleum coke by. Desulfurization by molten caustic leaching (MCL) method is another method for desulfurization of petroleum coke. Coke is mixed with alkali in this method. The solid form or a solution of the alkali is mixed with the . • Required a 97% reduction in the sulfur content of highway diesel fuel from ppm (low sulfur diesel, or LSD) to 15 parts per million (ultra-low sulfur diesel, or ULSD). • Refiners began producing the cleaner-burning diesel fuel, ULSD, for use in highway vehicles beginning June 1,

low sulfur content. This combination of properties makes the old-deep crudes the most desirable: they require little refining to remove sulfur and they can be converted to large quantities of high-quality products such as gasoline (see below). Unfortunately, less than 5% of the world's remaining petroleum reserves are of this quality.

6 coal tends to be highest in the lowest-boiling fractions. At least 95% of the sulfur in the light and middle oils is in the form of thiophene and C 1 - to C 3-substituted thiophenes.

The abundance of these species increases with the level of alkyl substitution. removal of sulfur from petroleum distillates in a refinery. Although HDS can eliminate aliphatic and cycle sulfur containing compounds effectively, it needs high temperature and high hydrogen pressure, which leads to many problems such as high investment, high operating cost and reduction.

Petroleum is composed primarily of hydrocarbons, although hydrocarbon derivatives containing oxygen, nitrogen, or sulfur are also present. Additionally, some metals are present at trace levels. Different sources of petroleum exhibit different compositions, however the major hydrocarbon classes (alkanes [paraffins], cycloalkanes [naphthenes], and aromatics) 2 are found in all sources of crude oil.

These petroleum fractions contain a high proportion of sulfur, oxygen, nitrogen compounds and metals and pollutants that reduce the performance of these petroleum fractions (Alaei Kadijani and Narimani, ). The presence of sulfur, nitrogen, oxygen compounds and metal compounds in crude oil have a significant negative impact on the quality of.

Sulfur content is another bulk parameter of a crude oil which reflects its quality and/or origin (Peters et al., ). It has an important impact on its economic value as it causes problems.

Petroleum sulfonate is one of the most important surfactants used in surfactant flooding for enhanced oil recovery, which is mainly obtained by treating high-boiling petroleum fractions in a.

A summary treatment of crude oil follows. For full treatment, see petroleum, petroleum production, and petroleum refining. Chemical and physical properties. Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and elements form a large variety of complex molecular.

Crude oils with more than %wt sulfur need to be treated extensively during petroleum refining. Using the sulfur content, crude oils can be classified as sweet (% %wt S). The distillation process segregates sulfur species in higher concentrations into the higher-boiling fractions and distillation residua.

A species-specific isotope dilution technique for accurate determination of sulfur species in low- and high-boiling petroleum products was developed by coupling capillary gas chromatography with. In addition to specific references, general reference sources are given, such as the U.

Low boiling fractions (up to °C) were analyzed by existing ASTM D (American Society for Testing and Materials, a) method for sulfur compound speciation.

As there is no standard method for the distribution of sulfur compounds in high boiling samples (up to °C), therefore, a methodology has been developed for the diesel range samples. Hill, • Handbook of Petroleum Refining Processes, third edition, Robert A.

Although it is generally true that the proportion of sulfur increases with the boiling point during distillation (Speight,), the middle fractions may actually contain more sulfur than higher-boiling fractions as a result of decomposition of the higher-molecular-weight compounds during the distillation.
