Abstract: Processes and apparatuses are disclosed for treating a naphtha stream from a FCC unit comprising passing the naphtha stream to a naphtha splitter column to provide a light naphtha stream and a heavy naphtha stream. The light naphtha stream is reacted in a mercaptan oxidation reactor to provide a demercaptanized naphtha stream. The demercaptanized naphtha stream is stripped in a light stripper column to provide a treated light naphtha stream and a bottoms stream.

Abstract: A process for the removal of residual sulfur compounds from rich liquid caustic is disclosed where a single column containing two reaction zones catalytically oxidizes mercaptans to disulfide oils. The second reaction zone utilizes a bundle of vertical hanging fibers and is maintained as a gas continuous phase comprising from about 20% to about 100% by volume vapor. This process is especially useful as part of a hydrocarbon desulfurization process flow scheme.

Abstract: A process to produce a sulfur-free hydrocarbon product stream from a liquid hydrocarbon disulfide product, e.g., of the Merox Process, includes subjecting the hydrocarbon disulfide to a catalytic oxidation step to produce SO2 which is separated from the remaining desulfurized hydrocarbons that form the clean sulfur-free hydrocarbon product stream; the SO2 is introduced into a Claus processing unit with the required stoichiometric amount of hydrogen sulfide (H2S) gas to produce elemental sulfur.

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: A method for reducing mercaptan concentration in a liquid hydrocarbon, comprising: contacting a mercaptan-rich liquid hydrocarbon having a first concentration of mercaptan sulfur with a composition comprising an oxidizing agent and water wherein the molar ratio of the oxidizing agent to mercaptan sulfur in the mercaptan-rich liquid hydrocarbon is from 3:1 to 10:1; and separating the water from the liquid hydrocarbon to yield a mercaptan-depleted liquid hydrocarbon having a second concentration of mercaptan sulfur, the second concentration being less than the first concentration; wherein a major amount of mercaptan compounds in the mercaptan-rich liquid hydrocarbon are converted to at least one sulfur oxoacid or salt thereof, having the formula: [RSOx]nY wherein R is a hydrocarbyl group; x is an integer from 1 to 3; n is 1 or 2; and Y is hydrogen, an alkaline metal, or alkaline earth metal.

Abstract: The present invention is directed to the use of a solution of a percarbonate compound to prevent fouling during the basic washing of hydrocarbons containing oxygenated compounds. More specifically, oxygenated compounds such as carbonyl containing organics have a tendency to polymerize, producing fouling elements when such are contained in hydrocarbons being washed with basic materials. Solutions of percarbonate compounds are quite effective in reducing the fouling tendencies due to these specific mechanisms.
