  • Safety Systems Depend on Reliable Field Sensors (Emphasis on Fire and Gas Detectors)

    Abstract Because not all hazards are the same, identifying and quantifying the hazard is the starting point in choosing sensing technology. Not all detectors are the same, and they should be selected according to their ability to detect the hazard. This paper gives a broad summary of technologies that provide users reliable responses to hazardous conditions, that minimise false ...

  • 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 ...

    The necessary data is: Physical stack height (m): This is the physical stack height in meters. Stack gas exit velocity vs (m/s): This is the stack gas exit velocity. It can be around 15 m/s. Stack ...

  • Using Open Path TDLAS CO2 Sensors for Carbon Capture and Storage Projects

    Public confidence in CCS projects worldwide is not very high. Many believe that CCS is not permanent storage, and at great expense to govermnents who are funding these projects. Effective monitoring and verification programs could go a long way to improve public perception.  Our Spectra-1 open path TDLAS gas sensor has shown very high accuracy in monitoring ambient CO2 levels. Better than ...

  • EPA studies identify techniques for critical leak testing prior to soil-vapor sampling

    Researchers at EPA’s National Risk Management Research Laboratory (NRMRL) in Ada, OK, are developing quality assurance (QA) measures for soil-gas and sub-slab sampling methods that help differentiate contaminant vapors due to vapor intrusion from background sources. Recent research focused on measures to identify leakage of ambient air into conventional vapor probes, which can significantly ...

  • Continuous measurement of Process oxygen for Claus sulfur recovery unit (sru) start-ups and shut-downs case study

    During start-up and shut-down, any time a sulfur recovery unit (SRU) transitions from ambient temperature through fuel gas warm up to the introduction of acid gas, measurement of 02 stoichiometry is critical. Historically, operators have manually taken samples using a portable electrochemical type Os analyzer. While giving more or less satisfactory results, the requirement for more stringent ...

  • A Review of 1-Hour NO2 NAAQS Air Quality Modeling

    During the development of this 4TR article, proposed revisions to Appendix W to 40 CFR Part 51 – Guideline on Air Quality Models (Guideline) were published in the Federal Register. As a result of revisions which propose to establish Tier 3 nitrogen dioxide (NO2) atmospheric chemical reaction screening techniques as default methods, ...

  • How to Save with Cooling Tower Credits

    Cooling towers dissipate heat from recirculating water used to cool chillers, air conditioners, or other process equipment to the ambient air. Heat is rejected to the environment from cooling towers through the process of evaporation. Therefore, by design, cooling towers use significant amounts of water. The thermal efficiency and longevity of the cooling tower and equipment depend on the proper ...
