sulfur dioxide (SO2) monitoring Applications

  • Sulfur Dioxide (SO2) monitoring

    Sulfur Dioxide (SO2) is the product of the combustion of sulfur compounds and causes significant environmental pollution. The main source of sulfur dioxide SO2 in the environment are from various industrial processes such as the burning of coal in power stations, the extraction of metals from ore and combustion of fuel within automobiles.

  • Total Reduced Sulfur (S) monitoring

    Total reduced sulfur(s), which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), occur naturally in the environment and can also be present in numerous industrial gaseous streams – petroleum refining, natural gas extraction, and chemical operations like the pulp/paper industry. Hydrogen sulfide is the most prevalent of the total reduced sulfurs, and is commonly found in volcanic gases, marshes and swamps, wetlands and mud flats,...

  • SO2 Monitoring in Air

    SO2 (sulfur dioxide) is measured in a number of applications. SO2 is used as a food grade preservative and must be regulated in accordance with government-set criteria to be safe for consumers. It is also measured in fuel exhaust to control for environmental pollution and in cement plants for process control.

    Fluoride emissions monitoring in aluminum smelters

    Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...
