Abstract: An apparatus and method for diluting and cooling that is extracted from high temperature and/or high pressure industrial processes. Through a feedback process, a specialized, CFD-modeled dilution cooler is employed along with real-time estimations of the point at which condensation will occur within the dilution cooler to define a level of dilution and diluted gas temperature that results in a gas that can be conveyed to standard gas analyzers that contains no condensed hydrocarbon compounds or condensed moisture.

Abstract: An apparatus for BTU measurement of natural gas having at least one reference spherical acoustic resonator containing a reference gas, a sample gas spherical acoustic resonator containing a natural gas sample, a first acoustic transmitter adapted to transmit a first acoustic signal into the natural gas sample, a second acoustic transmitter adapted to transmit a second acoustic signal into the reference gas, a first acoustic receiver adapted to receive at least a portion of the first acoustic signal, and a second acoustic receiver adapted to receive at least a portion of the second acoustic signal. Using the third radial resonance frequencies for the sample gas and reference gas, a data processor operably connected with a signal output of the first acoustic receiver determines the specific gravity of the natural gas sample. The discovered linear relationship between specific gravity and heating value of natural gas enables a determination of the heating value from the measured specific gravity.

The heated mixture is reformed by contact with a reforming catalyst external to, but proximate to the exit of, the tube bundle, forming a reformed fuel. To remove substantially all of the heat from the exhaust gases, a plurality of tube bundles and associated reforming catalyst arranged in series are provided.

Abstract: A method and apparatus for removing excess moisture from the evaporator coils of an air-conditioning system in which the moisture is removed from the evaporator coils by vibrating the coils. The coils may be vibrated by mechanical or acoustic devices such as solenoid plungers and acoustic transducers.
Abstract: A method and system for measuring heat energy of a combustible fluid in which light having wavelengths in the near-infrared is directed into a test cell containing the combustible fluid and portions of the light not absorbed by the combustible 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 combustible fluid. The system is spectrally calibrated by identifying known spectral features of the combustible gas absorbance spectrum. To correct for deviations in the original light source spectrum, a light source calibration system is employed.
Abstract: An apparatus for facilitating the use of tools on underground pipeline systems including a socket having a polygonal open end, a pliable socket insert having a polygonal outer circumference corresponding to the polygonal socket opening adapted to fit snugly into the polygonal opening and flush with the open end of the socket and a locking device by which the socket insert is maintained within the socket during use. The socket insert is provided with a plurality of pliant inwardly extending projections which deform to the size and geometry of the tool to be employed when the socket is pressed onto the tool.
