  • Publication number: 20160053183
    Abstract: Methods for hydrogen sulfide recycling using selective solvents in the hydroprocessing of renewable feedstocks are provided. An exemplary method includes the steps of combining hydrogen sulfide with renewable hydrocarbon feedstocks to form a first stream, deoxygenating the first stream to form a second hydrocarbon stream comprising deoxygenated hydrocarbons, water, carbon dioxide, and hydrogen sulfide, and separating the carbon dioxide and the hydrogen sulfide from the second hydrocarbon stream to form a third recycle stream comprising carbon dioxide and hydrogen sulfide. The method further includes the steps of selectively scrubbing the hydrogen sulfide from the third recycle stream to form a fourth recycle stream comprising carbon dioxide and a fifth recycle stream comprising hydrogen sulfide and selectively scrubbing the carbon dioxide from the fourth recycle stream.

  • Patent number: 8597375
    Abstract: A liquid separator system having a gas phase zone, an aqueous phase zone and a denser liquid zone is used to separate mixtures of fluids. The separator can be used for separating molten sulfur from liquid redox solution or reslurry water. The system includes a vessel with a top part and a bottom part. The vessel has a larger diameter at the top part than at the bottom part. The system also includes an inlet for introducing a redox solution or reslurry water and molten sulfur, which is denser than redox solution or reslurry water, into the vessel. An outlet near the bottom part of the vessel allows a flow of the molten sulfur from the vessel. An interface control structure senses an interface level between the redox solution or reslurry water and the molten sulfur, and the interface control structure controls the flow of molten sulfur from the outlet.
