摘要： A method and system remove hydrogen sulfide from a sour liquid. In an embodiment, the method for removing hydrogen sulfide from a hydrocarbon containing fluid includes contacting a methylmorpholine-N-oxide solution with the sour liquid. The method also includes allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide to remove the hydrogen sulfide.

摘要： An oxidative treatment process, e.g., oxidative desulfurization or denitrification, is provided in which the oxidant is produced in-situ using an aromatic-rich portion of the original liquid hydrocarbon feedstock. The process reduces or replaces the need for the separate introduction of liquid oxidants such as hydrogen peroxide, organic peroxide and organic hydroperoxide in an oxidative treatment process.

摘要： Oxidative dehydrogenation of paraffins to olefins provides a lower energy route to produce olefins. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, manufacture of glycols, and carboxylic acids and esters. Additionally, oxidative dehydrogenation processes can be integrated with the back end separation process of a conventional steam cracker to increase capacity at reduced cost.

摘要： The present disclosure relates to a process for reducing the sulphur content of hydrocarbon feedstocks such as Natural Gas Condensate, Kerosene, Jet Fuel, Diesel, Vacuum Gas Oil and Fuel Oil. The process uses a tailored oxidation process comprising one or two oxidation steps to produce sulphoxides and/or sulphones. These sulphoxides and sulphones, while being still present in the liquid hydrocarbon streams, are subsequently extracted thereby producing a low sulphur hydrocarbon stream and optionally following further treatment of the sulphoxides and/or sulphones, produce a low sulphur aromatic hydrocarbon stream and an aqueous stream of sodium sulphite or sulphuric acid. The low sulphur hydrocarbon stream and low sulphur aromatic hydrocarbon stream may be individually recycled or combined for recycling.

摘要： 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.

摘要： Embodiments of apparatuses and methods for conversion of mercaptans are provided. In one example, an apparatus comprises a vessel that is capable to receive a feed stream that comprises liquid hydrocarbons and the mercaptans. The vessel comprises a catalyst bed section that is capable of contacting the feed stream with a catalyst in the presence of oxygen (O2) and caustic at reaction conditions effective to oxidize the mercaptans and form a caustic-containing, sweetened liquid hydrocarbon-containing stream. A coalescing bed section is capable to coalesce and separate at least a portion of the caustic from the caustic-containing, sweetened liquid hydrocarbon-containing stream for forming a caustic-depleted, sweetened liquid hydrocarbon-containing product stream.

摘要： Provided herein in is a method of removing phosphorus from a liquid hydrocarbon that includes the steps of (a) contacting the liquid hydrocarbon with an aqueous solution that comprises an oxidizing agent to form a reaction mixture that comprises an aqueous component and a hydrocarbon component, wherein the liquid hydrocarbon comprises at least an alkene(C4-30), and a phosphine(C≦30); (b) reacting the oxidizing agent with the phosphine(C≦30) to form the corresponding phosphine oxide(C≦30); and (c) separating the aqueous component from the hydrocarbon component, thereby removing the phosphine oxide(C≦30) from the liquid hydrocarbon.

摘要： Disclosed herein are processes for producing and separating ethane and ethylene. In some embodiments, an oxidative coupling of methane (OCM) product gas comprising ethane and ethylene is introduced to a separation unit comprising two separators. Within the separation unit, the OCM product gas is separated to provide a C2-rich effluent, a methane-rich effluent, and a nitrogen-rich effluent. Advantageously, in some embodiments the separation is achieved with little or no external refrigeration requirement.
