  • Methods and apparatuses for producing hydrocarbons
    Patent number: 9670427
    Abstract: Methods and oil refinery apparatuses are provided for producing hydrocarbons. A method includes fractionating a crude oil feedstock to produce a crude saturated stream and a residual stream. The residual stream is cracked in a cracking device to produce an unsaturated stream, and the unsaturated stream and the crude saturated stream are combined to produce a combined stream. The combined stream is fractionated to produce a refinery fuel gas stream.
    Type: Grant
    Filed: November 18, 2014
    Date of Patent: June 6, 2017
    Assignee: UOP LLC
    Inventors: Sathit Kulprathipanja, Christopher McCormick, Joseph M. Ritchie

  • Coking with solvent separation of recycle oil using coker naphtha
    Patent number: 4530755
    Abstract: A coking process is provided in which a stream of heavy oil product, which typically is recycled to the coking zone, is first subjected to solvent separation using coker naphtha as solvent to separate the heavy oil into a high Conradson carbon content product comprising a minor portion of the coker naphtha and a lower Conradson carbon content product comprising a major portion of the coker naphtha and, thereafter, recovering the lower Conradson carbon content product and recycling the high Conradson content product, including the minor portion of coker naphtha, to the coking zone.
    Type: Grant
