Abstract:This project will development and field test a new portable, low-cost instrument for the measurement of hydrogen sulfites and mercaptans, which are routinely encountered in natural gas, renewable natural gas, biogas, landfill gas, etc. The instrument will allow the detection and measurement of such compounds at the part per billion (ppb) level, thus also serving as an artificial human nose. This highly innovative technology will greatly advance the state of the art, making ppb level measurements of mercaptans possible outside the realm of full size, benchtop laboratory grade, gas chromatograph instruments. Low levels of detection are needed in order to measure these compounds in alternative fuel gases where many times they exist as trace gases. In addition, such levels of detections are needed if the current practices of sniffing natural gas in order to determine appropriate level of odorization are to be replaced or enhanced. The work will build an engineering pre-commercial prototype system, based on an already proven concept, and will test it in the field. A follow up phase will be needed to build a market-ready instrument and commercialize it. This work will be conducted by a team consisting of NYSEARCH, the R&D organization within the Northeast Gas Association (NGA), and Applied Nanotech Inc. (ANI).
