Richard B. Macon 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).

  • Reduction of hydrocarbon losses in a molecular sieve hydrocarbon treating system
    Patent number: 4935399
    Abstract: Molecular sieves are used to remove sulfur compounds (e.g., COS and H.sub.2 S) from liquid hydrocarbon streams, particularly liquid propane. During regeneration of the sieves, some of the liquid hydrocarbons remains on the sieves and is lost be vaporization during the purge step and the liquid fill step. This invention reduces the loss by recovery and recycle of the vaporized hydrocarbons in the liquid recovery process.
    Type: Grant
    Filed: October 12, 1988
    Date of Patent: June 19, 1990
    Assignee: Amoco Corporation
    Inventors: Glen A. Blackburn, Richard B. Macon
