Patents by Inventor Paul John Hart

Paul John Hart 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).

  • Patent number: 7513972
    Abstract: The present invention discloses a comprehensive, efficient, and cost effective portable evaporator unit, method, and system for the treatment of brine. The evaporator unit, method, and system require a pretreatment process that removes heavy metals, crude oil, and other contaminates in preparation for the evaporator unit. The pretreatment and the evaporator unit, method, and system process metals and brine at the site where they are generated (the well site). Thus, saving significant money to producers who can avoid present and future increases in transportation costs.
    Type: Grant

    Date of Patent: April 7, 2009
    Assignee: Hart Resource Technologies, Inc.
    Inventors: Paul John Hart, Bruce G. Miller, Ronald T. Wincek, Glenn E. Decker, David K. Johnson
  • Patent number: 7022240
    Abstract: An apparatus and method for on-site treatment and reclamation of oil and gas well waste water or fracturing fluids. The mobile treatment process and apparatus provide both chemical precipitation and filtration to treat the drilling fluid waste to a technically and environmentally acceptable level allowing for reuse. Alkaline treating agents are applied to the drilling waste fluids, as they are pumped through the treatment apparatus, to increase the pH of the fluid waste to a preferred pH range and to also cause selective soluble contaminants in the fluids to form a precipitate. The waste fluid is allowed to clarify as the precipitate of insoluble contaminants, through flocculation, settle and form a sludge at the bottom of the drilling pit. The clarified fluids are then filtered to satisfy applicable industry and environmental requirements.
