Abstract: A desulfurization system has an oxidation process unit, and a multi-stage, liquid-liquid extraction unit in series with the oxidation process unit. The multi-stage, liquid-liquid extraction unit spits a fuel input from the oxidation process unit into a desulfurized fuel that is output for use, and a by-product. A solvent/sulfur/hydrocarbon separation process unit receives the by-product from the multi-stage, liquid-liquid extraction unit.

Abstract: A liquid-liquid extraction system includes extraction stages, a pumping system, and a controller. Each extraction stage has a chamber, a primary input, a raffinate output, and an extract output. An input liquid (e.g., either a source liquid or raffinate from a preceding extraction stage, mixed with an extraction liquid) is presented to the chamber via the primary input. The chamber enables phase separation of liquid therein, into a raffinate and a extract, where the raffinate exits the separation vessel at the raffinate output, and the extract exits the separation vessel at the extract output. A level sensor is coupled to the chamber and the controller is operatively programmed to read an output of the level sensor, compare the output of the level sensor to a target, and cause the associated chamber to receive additional liquid if the output is lower than the target.
