Patents by Inventor Marc L. Jacobs

Marc L. Jacobs has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Monomer recovery process
    Patent number: 5769927
    Abstract: A process for treating a purge vent stream from a polymer manufacturing operation, the vent stream containing a polymer, such as ethylene or propylene, and a purge gas, such as nitrogen. The invention involves three separation steps: condensation, flash evaporation and membrane separation. The steps are integrated together in such a way as to provide a good separation between the components, and to avoid creation of secondary streams that need additional treatment.
    Type: Grant
    Filed: January 24, 1997
    Date of Patent: June 23, 1998
    Assignee: Membrane Technology and Research, Inc.
    Inventors: Douglas Gottschlich, Marc L. Jacobs
  • Separation process combining condensation, membrane separation and flash evaporation
    Patent number: 5755855
    Abstract: A process for separating two low-boiling components of a gas-phase mixture. The invention involves three separation steps: condensation, flash evaporation and membrane separation. The steps are integrated together in such a way as to provide a good separation between the components, and to avoid creation of secondary streams that need additional treatment. The invention is particularly useful for separation of low molecular weight organic compounds from other gases.

    Assignee: Membrane Technology and Research, Inc.
    Inventors: Richard W. Baker, Kaaeid A. Lokhandwala, Douglas Gottschlich, Marc L. Jacobs
  • Membrane process for treatment of chlorine-containing gas streams
    Patent number: 5538535
    Abstract: A membrane process for separating chlorine from chlorine-containing gas streams is disclosed. The process employs a permselective membrane that is selective to chlorine and is stable in the long-term presence of chlorine. The process can be used to treat tail-gas from chlor-alkali plants, for example.
