    • Methods and systems of treating petroleum feedstock contaminated with naphthenic acids and sulfur are disclosed. The methods and systems include heating the petroleum feedstock to decompose the naphthenic acids, pressurizing to minimize the portion in the vapor phase, sweeping water vapor and carbon dioxide into a headspace with a non-oxidizing gas, removing water vapor and carbon dioxide from the headspace, reacting the sulfur with an alkali metal and a radical capping gas to convert the sulfur into alkali sulfides, and removing the alkali sulfides. Also disclosed is reacting the naphthenic acid with water and an oxide or hydroxide of an alkaline earth element to convert the naphthenic acid into naphthenates, removing water, ketonizing, removing oxides or carbonates, reacting the sulfur with an alkali metal and a radical capping gas to convert the sulfur into alkali sulfides, and removing the alkali sulfides.

    • Methods for removing sulfur from hydrocarbon streams using the sequential application of hydrodesulfurization, fractionation and oxidation. The hydrodesulfurization step is operative to remove easily-hydrogenated sulfur species, such as sulfides, disulfides and mercaptans. The resultant stream is then fractionated at a select temperature range to generate a sub-stream that is sulfur-rich with the sulfur species resistant to removal by hydrodesulfurization. The sub-stream is then isolated and subjected to an oxidative process operative to oxidize the sulfur species to sulfones or sulfoxides, which may then be removed by a variety of conventional methods, such as absorption. Alternatively, the methods may comprise using the sequential application of fractionation to generate a sulfur-rich sub-stream followed by oxidation and subsequent removal of the sulfur species present in the sub-fraction. The latter methods are ideally suited for transmix applications.
    • 使用加氢脱硫,分馏和氧化的顺序应用从烃流中除去硫的方法。 加氢脱硫步骤可操作以除去容易氢化的硫物质,例如硫化物,二硫化物和硫醇。 然后将所得物流在选择的温度范围进行分馏,以产生富含硫的亚烃,其中硫物质可通过加氢脱硫而被除去。 然后将该子流分离并进行氧化过程,以将硫物质氧化成砜或亚砜,然后可以通过各种常规方法(例如吸收)除去。 或者,所述方法可以包括使用分级分级的顺序应用来产生富含硫的子流,随后氧化和随后除去存在于亚部分中的硫物质。 后一种方法非常适合于传输应用。

    • Sulfur-containing compounds, including specifically thiophenic compounds, in a liquid hydrocarbon feedstream are catalytically oxidized by combining the hydrocarbon feedstream with a catalytic reaction mixture that includes a peroxide that is soluble in water or in a polar organic acid, at least one carboxylic acid, and a catalyst that is a transition metal salt selected from the group consisting of (NH 4 ) 2 WO 4 , (NH 4 ) 6 W 12 O 40 . H 2 O, Na 2 WO 4 , Li 2 WO 4 , K 2 WO 4 , MgWO 4 , (NH 4 ) 2 MoO 4 , (NH 4 ) 6 Mo 7 O 24 . 4H 2 O, MnO 0 and NaVO 3 ; the mixture is vigorously agitated for a time that is sufficient to oxidize the sulfur-containing compounds to form sulfoxides and sulfones; the reaction mixture is allowed to stand and separate into a lower aqueous layer containing the catalyst and an upper hydrocarbon layer that is recovered and from which the oxidized sulfur compounds are removed, as by solvent extraction, distillation or selective adsorption. The process can be used to reduce the sulfur content of liquid transportation fuels to 10 ppm, or less.
