SYSTEM AND METHOD FOR LIQUID HYDROCARBON DESULFURIZATION
A system for processing fuel to remove sulfur species through the oxidation of the sulfur species is disclosed 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 disclosed. The system and the method rely on the use of aqueous 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.

SYSTEM AND METHOD OF LIQUID HYDROCARBON DESULFURIZATION UTILIZING A LIQUID SORBENT
The disclosure is directed to a system and method of hydrocarbon desulfurization utilizing a liquid sorbent. The system includes a plurality of vessel pair assemblies, each of which includes a reaction vessel and a settling vessel. Hydrocarbon fuel having a sulfur content is mixed with a catalyst and an oxidant in each of the reaction vessels along with a sorbent and then transferred to the settling vessel for separating the hydrocarbon fuel having a sulfur content from the sorbent, the sorbent removing the oxidized portion of the sulfur from the hydrocarbon fuel. The sorbent is transferred from the second settling vessel to the first reaction vessel, while the hydrocarbon fuel having a sulfur content is transferred from the first settling vessel to the second reaction vessel so as to travel in opposing directions. Methods and other systems are likewise disclosed.
