  • Publication number: 20230055251
    Abstract: A method and apparatus for recovering water from a heated gas mixture. The heated gas mixture is passed across one or more heat pipe heat exchangers connected in series. Each heat pipe heat exchanger includes an upper chamber separated from a lower chamber, and sealed heat pipes extending between the chambers. The heated gas mixture is passed across the lower chamber, where the heated gas mixture is cooled with the plurality of heat pipes, passing heat into the heat pipe fluid and thereby condensing water vapor to liquid water on an outside of the of heat pipes. Ambient air or other gas of a cooling temperature is passed across the upper chamber to reduce the heated temperature controlled fluid inside the plurality of heat pipes.

  • Patent number: 10173915
    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.

  • Patent number: 8139222
    Abstract: A method and system for measuring a physical property of a fluid in which light having wavelengths in the near-infrared is directed into a test cell containing the fluid and portions of the light not absorbed by the fluid and passing out of the cell are spatially dispersed by wavelength, forming a light spectrum that is projected onto a detector. The light spectrum is digitized and inputted into a data processing unit in which it is compared to the actual spectrum of the light source stored in the system to determine the absorbance spectrum of the fluid. The system is spectrally calibrated by identifying known spectral features of the fluid absorbance spectrum. To correct for deviations in the original light source spectrum, a calibration method in which the pressure of the fluid in the test cell is alternated between a first positive pressure and a second positive pressure is employed.

  • Patent number: 8094301
    Abstract: A system and method for real-time monitoring of the interior of a combustor or gasifier wherein light emitted by the interior surface of a refractory wall of the combustor or gasifier is collected using an imaging fiber optic bundle having a light receiving end and a light output end. Color information in the light is captured with primary color (RGB) filters or complimentary color (GMCY) filters placed over individual pixels of color sensors disposed within a digital color camera in a BAYER mosaic layout, producing RGB signal outputs or GMCY signal outputs. The signal outputs are processed using intensity ratios of the primary color filters or the complimentary color filters, producing video images and/or thermal images of the interior of the combustor or gasifier.

  • Patent number: 7780436
    Abstract: A combustion method and apparatus which produce a hybrid flame for heating metals and metal alloys, which hybrid flame has the characteristic of having an oxidant-lean portion proximate the metal or metal alloy and having an oxidant-rich portion disposed above the oxidant lean portion. This hybrid flame is produced by introducing fuel and primary combustion oxidant into the furnace chamber containing the metal or metal alloy in a substoichiometric ratio to produce a fuel-rich flame and by introducing a secondary combustion oxidant into the furnace chamber above the fuel-rich flame in a manner whereby mixing of the secondary combustion oxidant with the fuel-rich flame is delayed for a portion of the length of the flame.
