  • Identifying Leaks from Natural Gas Pipelines at a Safe Distance

    The use of natural gas, of which methane is the principle component, is increasing worldwide. According to the American Petroleum Institute methane meets 24% of U.S. energy demand and heats over 50% of all U.S. households. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as ...

  • Impact of Sampling Media on Soil Gas Measurements

    Abstract To evaluate the vapor intrusion pathway for a building and to assess the associated human health risks, soil gas samples near the building site and under the building foundation may be collected. In order to meet risk assessment goals, the analytical laboratory is often required to report compounds of concern for these soil gas samples down to the part per billion ranges or lower. ...

  • Carbon Dioxide (CO2) Leak in Soda Machines

    Carbon dioxide, also known as CO2, is a very well known gas type but not everyone knows how deadly it is. Most people know it as a gas that humans exhale but commercially, it is manufactured and shipped as a liquefied compressed gas or is used as dry ice in its solid form. A common use of CO2 gas is in soda fountain machines to carbonate soft drinks by pressurizing the CO2 ...

  • Quantitative leak testing for soil gas wells using a commercially available helium tracer shroud

    In this paper we present design considerations, use, procedures and validation data for a commercially available Helium tracer soil gas sampling shroud that can be rented from an internationally accredited environmental testing laboratory with soil gas measurement capabilities. Soil Gas Sampling using the Helium shroud technique described in Appendix C, page 57, CA DTSC Soil Gas Advisory Document ...

  • Tackling Non-Revenue Water by Identifying Small Leaks

    Small leaks sink big ships – the same can be said for large-diameter pipes in utility networks. While large leaks or ruptures are seen as newsworthy stories accompanied by images of water flowing down the streets; smaller leaks can often be more devastating. Left undetected, they can add up over time, contributing significantly to ...

  • QuadOa and OGI: how EPA regulations are changing the way we look at gas leaks

    Earlier this year, the Environmental Protection Agency (EPA) published Regulation 40 CFR, Part 60, Sub-part OOOOa, commonly known as Quad Oa, and finally brought optical gas imaging (OGI) firmly into the mainstream. This presents a major shift in the way fugitive emissions are regulated, and the technology that can be used.  Detecting and acting on gas leaks is naturally a major ...

  • Case study - G200 detects N20 leak in sedation equipment at dental surgery

    About the customer Dental practice, Dover, England Challenge the customer faced A dental engineer was sent to investigate N2O problems at the dental surgery after complaints from staff about the effects of the gas. Previous passive monitoring in the surgery had indicated a time weighted average (TWA) of N2O at 90ppm, and a suspected leak in a faulty ...

  • Fugitive Gas Emissions In The Petroleum & Natural Gas Industry

    Challenge: Fugitive emissions in the petroleum and natural gas industry can come from a variety of sources and are classified as intentional (venting from tanks, compressor vents and stacks) or unintentional (equipment wear and tear, improper assembly, damage or manufacturing defects).  Most of these fugitive gas leaks are considered insignificant or  too small to ...

  • F-Gas Regulations - An Update

    How does the latest F-Gas Regulation affect refrigerant leak detection? January 2014 saw the revised EU Regulation of F-Gases following publication of a draft proposal by the European Commission at the end of 2012. The much anticipated regulation changes aim to strengthen the existing F-Gas Regulation and to ‘encourage’ the industry to move towards a HFC free market and use of ...

  • 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 ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Low level moisture measurement in Natural gas using a Lunable diode laser absorption spectroscopy (tdlas) based laser case study

  • Gas Analyser Unit

    Gas Analysers are used in several industries, chemical industries in particualr use gas analysers to monitor their gas emission levels, air quality samples are compared to high purity reference gases to analyse and measure the emissions.  A common practice is to “calibrate” the sample air against clean, dry pure reference gases such as H2, He, Ar, or N2. The ...
