Development of a portable odorant test instrument. Final report, October 15, 1981-April 15, 1983
The report describes the results of a laboratory program in which the feasibility of using solid-state semiconductor detectors to measure odorant levels in natural gas was studied. One type of sensor which employed a catalyst composed of the mixed oxides of lanthanum, strontium and cobalt in a Perovskite crystal structure could detect low-ppm concentration of sulfur-containing odorants at odorant-to-methane ratios typical of those found in odorized natural gas. A second sensor which used a thin film of pure tin oxide could also detect odorants in relatively high concentrations of methane but it was not as selective for odorant vs. methane as was the Perovskite material. Odorants commonly used by the gas industry were prepared as mixtures in cylinders of pressurized methane, certified at 50 ppm. Prepared sensors were placed in a glass test chamber of a dynamic flow system and exposed to concentration levels which varied from 1-50 ppm while operating over a temperature range from 190 C to 340 C.
