  • Publication number: 20070221538
    Abstract: The present disclosure is directed to a multi-stage system and a process utilizing said system with the design of reducing the sulfur-content in a liquid comprising hydrocarbons and organosulfur compounds. The process comprising at least one of the following states: (1) an oxidation stage; (2) an extraction state; (3) a raffinate washing stage; (4) a raffinate polishing stage; (5) a solvent recovery stage; (6) a solvent purification stage; and (7) a hydrocarbon recovery stage. The process for removing sulfur-containing hydrocarbons from gas oil, which comprises oxidizing gas oil comprising hydrocarbons and organosulfur compounds to obtain a product gas oil.

  • Patent number: 6596914
    Abstract: A multi-step process for desulfurizing liquid petroleum fuels that also removes nitrogen-containing compounds and aromatics. The process steps are: thiophene extraction; thiophene oxidation; thiophene-oxide and -dioxide extraction; raffinate solvent recovery and polishing; extract solvent recovery; and recycle-solvent purification. The thiophene oxidation is accomplished with hydrogen peroxide and the extraction solvent is acetic acid in combination with secondary solvents. The operating conditions in the process are relatively mild at near ambient pressure and less than 145° C. throughout the process, and the only chemical consumed in the process is hydrogen peroxide. The process design can be modified to accommodate a variety of liquid hydrocarbon feeds.
