Curt Graham 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).

  • Lng vapor handling configurations and methods
    Publication number: 20070125122
    Abstract: LNG vapor from an LNG storage vessel is absorbed using C3 and heavier components provided by a fractionator that receives a mixture of LNG vapors and the C3 and heavier components as fractionator feed. In such configurations, refrigeration content of the LNG liquid from the LNG storage vessel is advantageously used to condense the LNG vapor after separation. Where desired, a portion of the LNG liquid may also be used as fractionator feed to produce LPG as a bottom product.

  • Apparatus for control of a mobile machine
    Publication number: 20070062075
    Abstract: A control system for use with a mobile machine. The control system including a hand-grip bar having right and left curved sections. The curved sections each define an approximate center. The control system further including joysticks positioned at the approximate center of the curved sections. The curved sections each have a radius such that an operator can operate one or both joysticks without releasing his grip from the hand-grip bar.

  • Liquefied natural gas regasification configuration and method
    Publication number: 20070062216
    Abstract: Liquefied natural gas (LNG) is heated in a plant by a heat source and the heated LNG is expanded to produce work. In particularly preferred plants, the heat source is a combined cycle power plant, and the work is used to recompress pipeline gas produced from the heated LNG. Additionally, the refrigeration content in LNG may be utilized to increase the power generation capacity and efficiency of a combined cycle power plant.

  • Configurations and method for improved gas removal
    Patent number: 7192468
    Abstract: A plant includes an absorber (103) that operates in a gas phase supercritical region and removes an acid gas from a feed stream (9) at high recovery of the feed stream (10) while producing a high purity acid gas stream (36). Particularly preferred plants include gas purification plants that receive a feed gas with at least 5 mol % carbon dioxide at a pressure of at least 3000 psi.

  • Configurations and methods for acid gas and contaminant removal with near zero emission
    Publication number: 20060150812
    Abstract: A gas (1) comprising hydrogen sulfide, carbon dioxide, and hydrocarbon contaminants is treated in a plant (FIG. 2) in a configuration in which waste streams are recycled to extinction. In especially preferred aspects of contemplated methods and configurations, hydrogen sulfide and other sulfurous components are converted to a sulfur product (37), carbon dioxide (44A) is separated at a purity sufficient for enhanced oil recovery or sale, and hydrocarbon contaminants are purified to a marketable hydrocarbon product (49).

  • Twin reflux process and configurations for improved natural gas liquids recovery
    Patent number: 7051553
    Abstract: A two-column NGL recovery plant includes an absorber (110) and a distillation column (140) in which the absorber (110) receives two cooled reflux streams, wherein one reflux stream (107) comprises a vapor portion of the NGL and wherein the other reflux stream (146) comprises a lean reflux provided by the overhead (144) of the distillation column (140). Contemplat configurations are especially advantageous in a upgrade of an existing NGL plant and typically exhibit C3 recovery of at least 99% and C2 recovery of at least 90%.

  • Apparatus and method for speed control
    Publication number: 20060053926
    Abstract: An operator control system including a control bracket and levers. The control bracket is positionable at first and second position. When the control bracket is positioned in the first position, the levers have a maximum range of travel corresponding to a maximum range of available speed. When the control bracket is positioned in the second position, the levers have a limited range of travel that is less than the maximum range of travel.
