Monitoring the composition of fuel in natural gas engines using a compact ion mobility sensor. Topical report, December 1993-September 1994 (Final)
The present study has shown that the Westinghouse compact ion mobility sensor (IMS) is capable of distinguishing between the constituents methane, ethane, and propane in ternary mixtures of these gases at relative concentrations normally found in natural gas sources. Moreover, studies of binary mixtures of nitrogen and of carbon dioxide with methane have shown that the non-hydrocarbon constituents of natural gas can also be distinguished at the levels encountered in natural gas supplies. Further, no evidence of methane pulse broadening due to clustering reactions was observed at this level which indicates that no special provision is necessary to maintain very low levels of water vapor in the compact IMS. The present measurements have also shown that the individual ion signatures are determined with sufficiently high signal/noise ratio to provide concentration levels to an accuracy of 0.5%.
