  • Hydrocarbon treatment process
    Patent number: 9458392
    Abstract: In a catalytic treatment process, mercaptans in sour hydrocarbon are oxidized to disulfide oils using an aqueous treatment solution containing a chelated polyvalent metal catalyst, alkali metal hydroxide, and the alkali metal salt of at least one alcohol in a non-dispersive mixing apparatus wherein an upgraded hydrocarbon containing the disulfide oils is produced.
    Type: Grant
    Filed: November 3, 2014
    Date of Patent: October 4, 2016
    Assignee: MERICHEM COMPANY
    Inventors: Tiejun Zhang, K. Michael Hardy, V. Keith Turner, Ignacio C. Bincaz, Tom Varadi

  • Single vertical tower for treating a stream of rich caustic containing mercaptan compounds
    Patent number: 8454824
    Abstract: A separation process for separating two or more immiscible liquids using contactors utilizing high surface area vertical hanging fibers is disclosed. This separation process is especially useful in the separation of disulfide oil formed during the oxidation of spent caustic solution that was used to remove sulfur contaminates from light hydrocarbons.
