  • Device for microwave removal of NOx from exhaust gas
    Patent number: 6284202
    Abstract: The subject invention is a commercial device to effectively remove NOx and other pollutants from an exhaust gas stream. Microwave enhancement of oxidation/reduction catalysis is selectively employed as the exhaust gas stream traverses a bed of catalyst particles, which may operate as either a fixed or fluidized bed. An unique feature involves the conventional, non-microwave, conversion of NO to NO2; however, the subsequent reaction of reducing NO2 is microwave enhanced.

  • Process for microwave enhancement of gaseous decomposition reactions in solutions
    Patent number: 6046376
    Abstract: Gaseous decomposition from a solution is enhanced in the presence of activated carbon or its equivalent by radiofrequency energy in the microwave range. An important example is wet calcination using solutions containing bicarbonates, such as trona, where good conversion to carbonate is readily obtained. A further example is the excellent stabilization of solutions containing sulfites and bisulfites.

  • Method and apparatus for fluid analysis
    Patent number: 4312635
    Abstract: A fluid is circulated in a loop at a predetermined pressure and temperature. A second immiscible fluid is added to the loop and maintained in a portion of the loop so that a portion of the loop is free of the second immiscible fluid. A chemical tracer is added to the fluids and allowed to partition between them. Samples are taken of the mixture of first fluid and tracer from a portion of the loop free of the second fluid. From this sample, calculations may be made to determine the partition co-efficient of the fluids.
