  • 5th-Generation Thermox WDG Flue Gas Combustion Analyzer

    "For more than 40 years, we have been a leader in combustion gas analysis," says Mike Fuller, divison VP of sales and marketing and business development for Ametek Process Instruments, "and we believe the WDG-V is the combustion analyzer of the future." WDG analyzers are based on a zirconium oxide cell that provides a reliable and cost-effective solution for measuring excess oxygen in flue gas as ...

  • Analysis of Natural Gas Products by GC / TCD / FID

    The complex mixture of condensible hydrocarbons and permanent gases in a natural gas product has historically been separated on gas chromatographs equipped with dual columns and a switching valve. The light gases are separated from heavier compounds on a molecular sieve column, which is then backflushed onto a suitable column to separating the rest of the mixture. The Buck Scientific Model 910 ...

  • Expert insight: test method basics for oxidizer permit requirements

    Whenever a new oxidizer is installed to control Volatile Organic Compound (VOC) emissions, the question often comes up: What test method should I use to demonstrate that the device meets permit requirements?   Most states allow you the choice of three EPA Test Methods: 18, 25 and 25A. Of these, use of Method 25A is usually the most desirable, for a few reasons. One, Method 25A provides real ...

  • Waste Fuel Case History

  • TVOC measurement for LEED/green building evaluation

    Total Volatile Organic Compounds (TVOC) may be evaluated when building designers/managers are pursuing the Leadership in Energy and Environmental Design Green Building Rating System for New Construction (LEED-NC) EQ Credit 3.2. The latest LEED-NC guidance document specifies that the maximum allowed concentration of TVOC measured in a building (post construction, pre-occupancy) is 500 µg/m3; the ...


  • Triad expedites brownfields redevelopment in Fairbanks

    The Fairbanks North Star Borough (FNSB) used Triad in 2006-2007 to assess environmental conditions at a municipal property along the Chena River in Fairbanks, AK. FNSB accelerated the site investigation as part of a brownfields assessment grant received from the U.S. EPA in 2005. Low-level contamination had been identified onsite in past investigations, but its extent and impact on future ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...

  • Not All Hazards are the Same: Design considerations for matching flame and gas hazards to detector technologies

    Not all flame and gas hazards in facilities are the same, therefore the detection technology chosen should be specific to the type of hazard to be detected. How do users select technologies to see certain fires or detect certain gases? The intent of this paper is to give a broad introduction to the selection and use of flame and gas detector technologies. We will answer questions such as these: ...

  • The Use of Hydrogen Release Compound (HRC) for CAH Bioremediation.

    Hydrogen Release Compound (HRC™) is a simple, passive, low-cost and long-term option for the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) via a reductive dehalogenation pathway. Applications to other classes of chlorinated compounds that are anaerobically degradable by this mechanism are under investigation. HRC should be viewed as a tool for the enhancement of natural ...

  • Upgrading from Pellistor Gas Sensors to Infrared Technology

    In this article Andy Avenell, Crowcon’s Fixed Systems Product Manager, considers the shift towards infrared (IR) gas sensor technology in the oil and gas industry. Abstract Flammable gases and vapours can present considerable dangers in many industrial applications, none more so than the processes involved in extracting, transporting and processing oil and gas. Fast and reliable ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • A Chemical Dynamics Model for CAH Remediation with Polylactate Esters.

    ABSTRACT: The polylactate esters of sorbitol, xylitol and glycerol are a class of new chemical compounds that slowly release lactic acid into groundwater. The lactic acid is biotransformed into pyruvic acid and subsequently into acetic acid releasing hydrogen in both steps. The hydrogen is used by naturally occurring dechlorinating bacteria to reduce PCE to ethene by way of TCE, DCE and VC. A ...
