    Abstract: A method of reducing the formation of fouling deposits occurring in a caustic scrubber used to remove acid gases can include providing a caustic scrubber fed with an alkaline aqueous solution including essentially one or more of NaOH, KOH or LiOH. The method can include providing an olefin-containing hydrocarbon stream that is contaminated with oxygenated compounds and acid gases. The oxygenated compounds can be capable of making polymeric fouling deposits in the presence of the alkaline solution of the scrubber. The method can include sending the hydrocarbon stream to the caustic scrubber to recover an olefin-containing hydrocarbon stream that is essentially free of acid gases. An efficient amount of a solvent capable of reducing the formation of fouling deposits can be introduced in the caustic scrubber and/or in the alkaline solution fed to the scrubber. The solvent can be separated from the alkaline solution.

    Abstract: A one-step process for desulfurizing an oxidized sulfone-containing fuel stream, such as a diesel stream, is disclosed where mass transfer and conversion of sulfone occurs simultaneously such that the sulfur atom in sulfone molecule is removed as sulfite to provide a low-sulfur diesel stream. The diesel stream for treatment is obtained as a result of the oxidation of a thiophene-rich diesel stream with an oxidant to provide a sulfone-containing diesel stream. The one-step process uses a single vessel having a shroud of vertical hanging fibers to affect the mass transfer of sulfones in diesel into contacting with an aqueous solution of alkali metal hydroxide where it is converted to sulfite and biphenyls. The sulfite-rich aqueous solution and low sulfur diesel are then separately removed from the vessel.

    Abstract: Methods for converting petroleum based oil into fuel generally include forming a conversion mixture of an alcohol and a base, and adding the conversion mixture to petroleum based oil, such as used motor oil, to form a reaction mixture. The methods can also include adding a high nitrate compound and an amino acid to the reaction mixture and ozonizing the reaction mixture. The result of the methods can include a three phase system in which the bottom phase is asphalt oil, the middle phase is diesel fuel or jet fuel, and the top phase is sulfuric acid. The three phases can be separated to obtain the final diesel fuel or jet fuel product.
