  • Applications of a Portable Gas Spectrometer

    In the realm of natural gas processing, enterprises don’t always find it economical to send products back to the lab and wait for test results. Being able to perform on-the-spot, highly accurate compositional analysis with gas chromatography equipment can reduce operational costs and help companies determine on-the-spot accurate gas levels in a natural gas stream. ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • Another source of methane release

    Mary Kang wasn’t even originally looking at methane emissions. The Princeton doctoral candidate was trying to get to the bottom of another issue: carbon dioxide escaping after being stored underground. During that research, she got to wondering about methane emissions from old oil and natural gas wells. What Kang, now a Stanford postdoctoral researcher, and other researchers found could be ...

  • Methane as an energy source for the 21st century

    Today, fossil fuels supply about 80% of global primary energy. The consequences are severe for human health from indoor and regional air pollution, acidification due to sulphur and nitrogen oxide emissions and climate change due to rapidly growing greenhouse gas emissions. Therefore, there is a clear need to improve the efficiency and the environmental compatibility of fossil technologies, shift ...

  • Methane Emissions From Terrestrial Plants

     In a recent issue of Nature Keppler et al. [2006] report the discovery that terrestrial plants emit CH4 under aerobic conditions. Until now it was thought that bacterial decomposition of plant material under anaerobic conditions, such as in wetlands and water flooded rice paddies, is the main process leading to emissions from terrestrial ecosystems. In a first attempt to upscale these ...


  • Capturing the fugitives: Reducing methane emissions from natural gas

    The rapid expansion of natural gas development in the United States has been a double-edged sword. While natural gas supporters are quick to point out its economic benefits and green attributes—natural gas produces roughly half the carbon dioxide emissions of coal during combustion—this isn’t the whole story. Natural gas comes with environmental consequences, including risks to ...

  • New study sheds light on methane leakage from natural gas

    Natural gas wells represent a significant source of U.S. greenhouse gas (GHG) emissions, as many of them leak methane, which is more than 20 times more potent than carbon dioxide. But while scientists know that ...

  • Strategy Paper for Reducing Methane Emissions

    The Strategy Paper for reducing methane emissions,which has just been approved by the Commission, describes the contribution man-made methane emissions, both at the global and European level, are making to the greenhouse effect and global warming. Although the focus in the global climate debate has often been on CO2 emissions, the major greenhouse gas, it needs to be underlined that methane is ...

  • Reducing Oil & Gas Methane Emissions: EPA Regulations & Data Collection

    U.S. President Barack Obama and Canadian Prime Minister Justin Trudeau recently committed to very specific targets in the oil and gas sector. Their ambitious goal is to reduce methane emissions by 40-45 percent below 2012 levels by 2025. This target was reaffirmed ...

  • A close look at fugitive methane emissions from natural gas

    Natural gas is booming in the United States. Production has increased by 20 percent in the last five years, fueled largely by technological advances in shale gas extraction. Other countries–including China–are now studying our ...

  • Headspace gas chromatography with flame ionization detection (HS-GC-FID) for the determination of dissolved methane in wastewater

    There is currently a need for a simple, accurate and reproducible method that quantifies the amount of dissolved methane in wastewater in order to realize the potential methane that can be recovered and account for any emissions. This paper presents such a method, using gas chromatography with flame ionization detection fitted with a GS-Gas PRO column coupled with a headspace auto sampler. A ...

  • Spray-applied barrier is proven methane mitigation solution on former gas station site case study

    Project: Rite-Aid Pharmacy Location: Prospect Park, PA Products: Liquid Boot Gas Vapor Mitigation System Background: Situated on a former gas station site, elevated levels of petroleum hydrocarbons were detected in the soil. The area was a prime location for the retail facility and solutions to mitigate the contamination were ...

  • 5 things to know about Obama`s next climate move: methane

    The Obama administration on Wednesday announced its latest move to combat global warming, this time trying to rein in heat-trapping methane gas that escapes from oil and gas fields. The plan relies on voluntary steps and new rules to reduce leaks from oil and gas production by 40 percent to 45 percent over the next decade. In a way, the proposal is an effort to plug what many viewed as a hole in ...

  • How big a problem are methane emissions and what can we do about it?

    Methane emissions and their climate effects have been given an increasing amount of attention over the last few years from academia, industry and policy makers. The US Environmental Protection Agency (EPA) have lead the way in proposing new performance ...

  • 5 Reasons why it’s (still) important to reduce fugitive methane emissions

    The U.S. Environmental Protection Agency (EPA) recently released its annual greenhouse gas (GHG) inventory report. Using new data and information, the EPA lowered its estimate of fugitive methane emissions from natural gas ...

  • Measuring methane at the UK`s first viable compact anaerobic digester plant

    At the UK's first viable compact anaerobic digester (AD) plant aimed at local food waste treatment, a Geotech GA3000 fixed biogas analyser monitors methane (CH4), carbon dioxide (CO2), oxygen (O2) and hydrogen sulphide (H2S). The plant, a modular scalable AD system, unveiled by React Environmental in July 2012 at Llangadog, Carmarthenshire, can handle some 1,000 ...

  • EPA proposes dropping plan to write effluent guidelines for coalbed methane

    The Environmental Protection Agency is proposing to drop its plan to develop effluent guidelines for coalbed methane extraction, according to a notice scheduled for publication Aug. 7. EPA's notice, summarizing a biennial report on preliminary effluent guideline plans, said it was proposing the change ...

  • New Study Raises Big Questions on U.S. Fugitive Methane Emissions

    A new study in the Proceedings of the National Academy of Sciences sheds light on a question that continues to vex industry executives and policymakers alike: How significant are fugitive methane ...

  • Utilisation of Methane to Generate Electricity: BHP Appin and Tower Collieries

    Background BHP Collieries Division operates five underground coal mines in and around the Illawarra region of NSW. They include the Appin and Tower mines which are situated north-west of Wollongong and some 75 kilometres from Sydney. These two mines produce around 3.5 million tonnes of coal per year which is primarily used for domestic steel making. Some coking and energy coal is also ...
