Abstract: Oil and gas industry, an important and overarching component of Russian economy, creates critical safety problems. One of the key safety issues is related to sulfur-containing oil and gas compounds. The latter particularly include hydrogen sulfide and thiols (mercaptans) that are Hazardous Chemicals (HC) and Top-Priority Air Pollutants (TPAP) on their own. Combustion of these compounds produces sulfur dioxide which is also both HC and TPAP. Thus, it is vital to search for methods and means to control the content of these substances both in the atmosphere and in the processing and the fuel gas, used at the gas and the oil extraction facilities as well as in natural gas and oil chemistry. We analyzed new rapidly developing sensors for determination of concentrations of various trace constituents in gas media. These technological tools, based on solid state gas sensors of different types, bear promising advantages for the task of measuring concentrations of sulfur-containing gas impurities both in the atmosphere and in the processing media. Concusion current study describes the most common sensors for sulfur-containing gas substances. These sensors implement electrochemical cells with solid-state electrolyte, metal oxide and traditional silicon semiconducting materials and structures, mass-sensitive piezo-quartz cells, running on surface or volume waves, passive and active optical elements. We evaluate static and dynamic qualities of these sensors as well as their consumer properties.
