A liquid hydrocarbon desulfurization system having at least one processing unit, and preferably an initial and an end processing unit. Each processing unit having a reactor assembly and a sorption system. An aqueous system directs aqueous into the reactor assembly together with liquid hydrocarbon, wherein the two are mixed using shear mixers. An adsorbent system provides adsorbent to the sorption column to adsorb the oxidized sulfur resulting through the mixing of the liquid hydrocarbon with the aqueous. A system having multiple processing units is disclosed, as well as systems for transferring adsorbent and providing aqueous. A plurality of methods is likewise disclosed.

System and method for liquid hydrocarbon desulfurization

A reaction column comprises a plurality of cells each of which has a lower cell portion and an upper cell portion. The cells are arranged sequentially, from an uppermost cell to a lowermost cell. The fuel inlet is configured to direct fluid through the reaction column from a lower cell portion of the lowermost cell to an upper cell portion of the uppermost cell, and out of the fuel outlet. The reagent inlet is configured to direct reagent through the reaction column from the upper cell portion of the uppermost cell to the lower cell portion of the lowermost cell. The plurality of cells may be vertically or horizontally positioned, as well as inclined and the like. Systems and methods are likewise disclosed.

System and method for desulfurization of hydrocarbon fuels

System for liquid hydrocarbon desulfurization

A system for processing fuel to remove sulfur species through the oxidation of the sulfur species is described which includes one or more (and preferably two or more processing units). Additionally, a method of removing sulfur species through the oxidation of the sulfur species is also described. The system and the method rely on the use of aqueous feed and does not require the removal (through sorption or the like) at each or between each processing unit. Such a configuration for numerous reasons is economically advantageous.

A system for liquid hydrocarbon desulfurization having at least one reaction subsystem including at least one high intensity mixer and a stripping station. Multiple reaction subsystems can be utilized. A method is likewise disclosed for liquid hydrocarbon desulfurization.

A method of desulfurizing a liquid hydrocarbon comprises providing an initial processing unit and an end processing unit, the initial processing unit having an initial reactor assembly and an initial sorption system, the end processing unit having an end reactor assembly, a separator and an end sorption system. The method further comprises feeding a liquid hydrocarbon having a sulfur content into the initial reactor assembly, feeding an aqueous feed into the initial reactor assembly, shear mixing the liquid hydrocarbon and the aqueous feed within the initial reactor assembly, to, in turn, react the aqueous feed with the sulfur content of the liquid hydrocarbon, and directing the liquid hydrocarbon and aqueous feed to the initial sorption system. The method even further comprises feeding a sorbent into the initial sorption system and adsorbing at least some of the sulfur content that has reacted with the aqueous feed from the liquid hydrocarbon.
