The present invention provides an internal olefin sulfonate composition, comprising water and an internal olefin sulfonate mixture having an average carbon number of at least 20, wherein the internal olefin sulfonate mixture comprises hydroxy sulfonates and alkene sulfonates in a weight ratio of hydroxy sulfonates to alkene sulfonates of at least 3.25. The invention further provides a method of treating a crude oil containing formation.

Internal olefin sulfonate composition

The invention relates to a method of treating a hydrocarbon containing formation, comprising the following steps: a) preparing an internal olefin sulfonate, comprising sulfonating an internal olefin into sulfonated internal olefin followed by contacting sulfonated internal olefin with a base containing solution resulting in the internal olefin sulfonate, wherein sulfonated internal olefin is contacted with the base containing solution in the presence of a non-ionic surfactant, and/or after step a) but before step b), the internal olefin sulfonate and said non-ionic surfactant are combined; b) transporting an aqueous solution comprising the internal olefin sulfonate and the non-ionic surfactant to the location of the hydrocarbon containing formation; c) providing the internal olefin sulfonate and the non-ionic surfactant to at least a portion of the hydrocarbon containing formation; and d) allowing the internal olefin sulfonate and the non-ionic surfactant to interact with the hydrocarbons in the hydrocarbon containing formation.

Method for enhanced hydrocarbon recovery

The invention relates to a hydrocarbon recovery composition comprising an anionic surfactant, wherein said composition is in the solid state, and to a shaped article comprising said composition. Preferably, said composition is in the form of a powder. Further, the invention relates to a process for treating a hydrocarbon containing formation comprising the steps of a) transporting said composition or shaped article to the location of the hydrocarbon containing formation; b) dissolving said composition or shaped article in water thereby forming an aqueous fluid containing the hydrocarbon recovery composition; c) providing the aqueous fluid containing the hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation; and d) allowing the hydrocarbon recovery composition to interact with the hydrocarbons in the hydrocarbon containing formation.

Composition and method for enhanced hydrocarbon recovery

The invention relates to a process for preparing an internal olefin sulfonate, comprising sulfonating an internal olefin into sulfonated internal olefin followed by contacting sulfonated internal olefin with a base containing solution, wherein the molar ratio of internal olefin to solvent for the base is higher than 0.06. Further, the invention relates to an internal olefin sulfonate obtainable by said process.

Systems and methods to produced branched aliphatic alcohols are described. Systems may include a dehydrogenation-isomerization unit, an olefin dimerization unit, an olefin isomerization unit, a hydroformylation unit, a dehydrogenation unit, a hydrogenation unit and/or combinations thereof. Methods for producing branched aliphatic alcohols may include isomerization of olefins in a process stream. The isomerized olefins may be hydroformylated to produce aliphatic alcohols. After hydroformylation of the aliphatic alcohols, unreacted components from the hydroformylation process may be separated from the aliphatic alcohols products. The unreacted components from the hydroformylation process may be recycled back into the main process stream or sent to other processing units. Addition of multiple streams to the units may be performed to control reaction conditions in the units.

A process for the preparation of detergents involving separating the hydrocarbonaceous product stream from a Fischer-Tropsch process producing normally liquid and normally solid hydrocarbons into a light fraction and one or more heavy fractions, hydrogenating at least part of the light fraction to convert unsaturated hydrocarbons and/or oxygenates into saturated hydrocarbons, distilling product thus obtained into at least one fraction comprising detergent hydrocarbons, dehydrogenating at least part of the detergent hydrocarbons to obtain a detergent hydrocarbon stream having mono-olefins and converting the mono-olefins into detergents. The invention further concerns a process for the preparation of detergents in which process a hydrogenated product, which is obtained according to the above process, is dehydrogenated to obtain a detergent hydrocarbon stream of mono-olefins, followed by conversion of the mono-olefins into detergents. Further, the invention relates to the combined production of detergents or detergent hydrocarbons and fuels from Fischer-Tropsch hydrocarbonaceous reaction product.
