  • 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 ...

  • Detecting Gases: What You Can`t Smell Can Hurt You

    Walking through a drill-site area, a worker smells rotten eggs and stops tor a minute or two to assess where a gas leak might exist. Rubbing his itchv eves as he investigates further, he notices that he no longer smells the tell¬tale hydrogen sulphide odour. He does not realize that the gas has deadened his olfactory senses and unless he leaves the area within seconds, he could lose ...

  • Characterization of Fugitive Emissions of Greenhouse Gases from a Wastewater Treatment Plant Using The Radial Plume Mapping Technique

    An existing anaerobic wastewater treatment plant (WWTP) near Bucaramanga, Colombia is being upgraded to include nitrification/denitrification and improvements in capture and recovery of methane. The existing plant utilizes upflow anaerobic sludge blanket (UASB) reactors followed by facultative lagoons. For this project, the UASB reactors will be retrofit to maximize the collection of biogas, and ...
