  • Process for the production of alkenes and/or aromatic compounds
    Patent number: 9512049
    Abstract: Processes for the production of alkenes are provided. The processes make use of methane as a low cost starting material.
    Type: Grant
    Filed: December 21, 2012
    Date of Patent: December 6, 2016
    Assignee: Dow Global Technologies LLC
    Inventors: Max Markus Tirtowidjojo, Brien A. Stears, William J. Kruper, Jr., Kurt F. Hirsekorn, Debashis Chakraborty
  • BRINE MINING PROCESS
    Publication number: 20160272513
    Abstract: The present invention relates to a brine mining process. The process incorporates a forward osmosis step wherein at least a portion of at least one process stream is provided to at least one forward osmosis unit. The process thus allows for the use of multiple sources, and qualities, of water, which, in turn, can reduce the reliance on natural water sources. Longevity of the mining, and any downstream, process equipment may be enhanced. At least a portion of the production stream may also be fed to a downstream process, such as a chlor-alkali process.

  • Process for the production of chlorinated propanes and propenes
    Patent number: 9334205
    Abstract: Processes for the production of chlorinated propanes and propenes are provided. The present processes comprise catalyzing at least one chlorination step with one or more regios elective catalysts that provide a regioselectivity to one chloropropane of at least 5:1 relative to other chloropropanes.
    Type: Grant
    Filed: December 12, 2012
    Date of Patent: May 10, 2016
    Assignee: Blue Cube IP LLC
    Inventors: Max Markus Tirtowidjojo, Matthew Lee Grandbois, William J. Kruper, Edward M. Calverley, David Stephen Laitar, Kurt Frederick Hirksekorn
  • Process for the production of tetrachloromethane
    Patent number: 9169177
    Abstract: Processes for the production of tetrachloromethane are provided. The present processes involve catalyzing the chlorination of a feedstream comprising partially chlorinated methanes with a free radical initiator. Cost savings are thus provided relative to conventional processes that require the use of high temperatures and/or pressures, and safety concerns are alleviated or eliminated.
    Type: Grant

    Date of Patent: October 27, 2015
    Assignee: BLUE CUBE IP LLC
    Inventors: Max Markus Tirtowidjojo, Danny Eugene Randolph
  • Processes for the production of hydrofluoroolefins
    Patent number: 8933280
    Abstract: The present invention provides continuous, gas phase, free radical processes for the production of chlorinated and/or fluorinated propenes or higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes, wherein wherein at least a portion of any intermediate boiler by-products generated by the process are removed from the process.
    Type: Grant
    Filed: October 4, 2013
    Date of Patent: January 13, 2015
    Assignee: Dow Global Technologies LLC
    Inventors: Max Markus Tirtowidjojo, Patrick Ho-Sing Au-Yeung, Debashis Chakraborty, Juergen Eiffler, Heinz Groenewald, Kurt Frederick Hirsekorn, Manfred Kokott, William J. Kruper, Jr., Thomas Ulrich Luebbe, Holger Meeman, Shirley Shaw Sexton, Peter Wenzel, Marcus Wobser
  • Isothermal multitube reactors
    Patent number: 8926918
    Abstract: The present invention provides isothermal multitube reactors suitable for the production of chlorinated and/or fluorinated propene and higher alkenes from the reaction of chlorinated and/or fluorinated alkanes and chlorinated and/or fluorinated alkenes. The reactors utilize a feed mixture inlet temperature at least 20° C. different from a desired reaction temperature.
