  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Case-study - Improving monitoring, reporting and verification of greenhouse gas emissions

    Greenhouse gas (GHG) inventories are used by businesses, governments and members of the public as they provide levels of allowable carbon emissions and details of how emissions can be reduced. Some industrial sectors have high uncertainties in their MRV results which presents a barrier to carbon dioxide reductions. MRV Sector aims to improve and increase the accuracy of monitoring techniques in ...

  • Portable laser gas detector systems for landfill CH4 and CO2 monitoring

    There has recently been a marked increase in interest in detecting and quantifying emissions of the greenhouse gases (GHG) carbon dioxide (CO2) and methane (CH4) from landfills in North America and Europe. The primary drivers for this increased interest are: new and pending legislation requires demonstrated reductions in GHG emissions; permits to expand existing facilities require more accurate ...

  • A Comparison of Point Sensors and Open Path Monitors For Toxic Gas (esp. HF) Monitoring

    Point Sensors Ion Mobility Spectroscope (IMS) – a gas sample is ionized by a radioactive source (Ni63). Differences in ion drift under the influence of an applied electric field produce a spectrum that is dependent on the mass, charge, and shape of the component ions. The detector signal and strength is tuned to the drift time of the ion of interest (in this case HF) and signal strength is ...
