  • Publication number: 20130035528
    Abstract: A system and method for processing biomass into hydrocarbon fuels that includes processing a biomass in a hydropyrolysis reactor resulting in hydrocarbon fuels and a process vapor stream and cooling the process vapor stream to a condensation temperature resulting in an aqueous stream. The aqueous stream is sent to a catalytic reactor where it is oxidized to obtain a product stream containing ammonia and ammonium sulfate. A resulting cooled product vapor stream includes non-condensable process vapors comprising H2, CH4, CO, CO2, ammonia and hydrogen sulfide.

  • Publication number: 20120315586
    Abstract: A method and apparatus for combustion in which a pressurized preheated liquid fuel is atomized and a portion thereof flash vaporized, creating a mixture of fuel vapor and liquid droplets. The mixture is mixed with primary combustion oxidant, producing a fuel/primary oxidant mixture which is then injected into a primary combustion chamber in which the fuel/primary oxidant mixture is partially combusted, producing a secondary gaseous fuel containing hydrogen and carbon oxides. The secondary gaseous fuel is mixed with a secondary combustion oxidant and injected into the second combustion chamber wherein complete combustion of the secondary gaseous fuel is carried out. The resulting second stage flue gas containing very low amounts of NOx is then vented from the second combustion chamber.

    Abstract: A method for external repair of a leak in an in-service fluid containment vessel in which a fluid venting device is affixed to the outer surface of the fluid containment vessel so as to enable venting of the leaking fluid to the atmosphere during the remainder of the method steps. A composite repair material is applied over the fluid venting device and the fluid containment vessel and allowed to cure. During the curing period, fluid leaking from the fluid containment vessel is vented to the atmosphere. After curing of the composite repair material, a sealant is provided to the leak by way of the fluid venting device.

  • Publication number: 20120210751
    Abstract: A method for removing gaseous inclusions from a viscous liquid in which a viscous liquid stream having gaseous inclusions is introduced into a refining chamber, resulting in a flowing viscous liquid layer. The viscosity of a bottom portion of the viscous liquid layer is reduced in a first refining zone in the refining chamber so as to produce an upwardly mobile reduced viscosity portion of the viscous liquid layer. Heat is introduced into the viscous liquid layer from above the viscous liquid layer in a second refining zone in the refining chamber downstream of the first refining zone, reducing the gaseous inclusions in said viscous liquid layer. Thereafter, the viscous liquid layer having substantially reduced gaseous inclusions is discharged from the refining chamber.

    Abstract: A method and apparatus for absorbance correction in a spectroscopic heating value sensor in which a reference light intensity measurement is made on a non-absorbing reference fluid, a light intensity measurement is made on a sample fluid, and a measured light absorbance of the sample fluid is determined. A corrective light intensity measurement at a non-absorbing wavelength of the sample fluid is made on the sample fluid from which an absorbance correction factor is determined. The absorbance correction factor is then applied to the measured light absorbance of the sample fluid to arrive at a true or accurate absorbance for the sample fluid.

  • Patent number: 8205559
    Abstract: An apparatus for transporting a payload along the inside of a substantially horizontal pipe, which apparatus includes a pair of spaced apart, vertically aligned, relationally pivotably connected, rollable pipe tracking contactors, wherein pivoting of one of the pipe tracking contactors in a first direction results in pivoting of the other pipe tracking contactor in a direction opposite to the first direction. The apparatus further includes a control system which is used to maintain the vertical alignment of the pipe tracking contactors and which includes a two-dimensional tilt sensor that provides information to a controller regarding the orientation of the apparatus. Using the information from the sensor, the controller is able to correct both the lateral position and the speed of the contactors to bring the apparatus back into vertical alignment.

  • Publication number: 20120118568
    Abstract: A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.

  • Patent number: 8156810
    Abstract: A method for characterizing a defect of a defective heat fusion joint connecting two pipe segments in which the time of flight of an ultrasonic waveform reflected off an exterior surface of a heat fusion joint fitting connecting the two pipe segments or reflected off an interior wall of one of the pipe segments at a plurality of locations around the circumference of the heat fusion joint fitting is measured to determine the minimum and maximum times of flight, which correspond to the maximum and minimum combined wall thicknesses of the heat fusion joint fitting connecting the pipe segments and the pipe segment wall. If the difference between the minimum and maximum combined wall thicknesses as determined from the measured times of flight is equal to or greater than a predetermined amount, then the heat fusion joint is defective and possibly unacceptable for use, requiring a second set of time-of-flight measurements to characterize the nature of the defect.
