  • Ethylene separation process
    Patent number: 9688591
    Abstract: Ethylene separation processes are described herein. The ethylene separation processes generally include introducing a feed stream including ethylene and butene into a de-ethenizer; and separating the ethylene from the butene via fractional distillation within the de-ethenizer to form an overhead stream including separated ethylene and a bottoms stream including separated butene, wherein the de-ethenizer operates at a pressure of less than 350 psig.
    Type: Grant
    Filed: January 10, 2013
    Date of Patent: June 27, 2017
    Assignees: Equistar Chemicals, LP, Lyondell Chemical Technology, L.P.
    Inventors: Gary A. Sawyer, Robert S. Bridges, Steven T. Coleman, Allen David Hood, Jr.

  • Fractional extraction of butadiene
    Patent number: 8222474
    Abstract: A method for the solvent extraction of 1,3-butadiene from a mixture of C4 hydrocarbons that employs a distillation tower to produce the desired 1,3-butadiene product as an overhead and a separate bottoms stream that is removed from and not recycled in the solvent extraction process.

  • Extractive distillation
    Patent number: 7718841
    Abstract: A method for reducing corrosion in a diolefin extractive distillation process comprising preventing the formation of ammonium carbonate by promoting the formation of a carbonate salt that does not dissociate in the ammonium carbonate dissociation temperature range of that extractive distillation process.
