  • Methane Number

    Did you know that the methane number of a gas provides an indication of the knock tendency of a fuel? It is a product of the different constituent gases within the natural gas, particularly the proportions of methane, ethane, propane and butane. Understanding the knock resistance is important when specificing an engine for a gas-powered ...

  • Where To Find Money In Biogas

    On the surface, wastewater treatment operations don’t appear to be handling precious material. But these facilities are actually processing a great deal of value every day. Sludge, a byproduct of wastewater treatment, turns out to be an entity worth cherishing. “Depending on treated sludge quality, the final product can be land applied, landfilled, incinerated, or composed,” ...

  • A laboratory assessment of the impact of brewery wastewater discharge on sulfide and methane production in a sewer

    The impact of brewery wastewater discharge on sulfide and methane production in a sewer was assessed. Experiments were carried out on laboratory scale sewer reactors consisting of both an experimental and a control reactor. The control reactor was intermittently fed with real fresh sewage while the experimental reactor was fed with a mixture of brewery and domestic wastewater at two different ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Power generated from methane gas in disused mines in England

    Type     HOFGAS®-IPM/C 2500 Performance     2’500 Nm³/h / 520mbar dP Location     England (GB) Situation Mine gas is released when coal is extracted. This gas is sourced not only from working coal mines but also from those that were closed down long ago. Because large quantities of coal remain in the mine after it has ...

  • 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 ...

  • Production of methane gas from organic fraction municipal solid waste (OFMSW) via anaerobic process: application methodology for the Malaysian condition

    Solid waste management in Malaysia is confronted with many problems, including low collection coverage, irregular collection services, inadequate equipment used for waste collection, crude open dumping and burning without air and water pollution control systems, inadequate legal provisions and resource constraints. These problems have various effects on the development of the solid waste ...

  • Monitoring the oxygen content in bio-methane-to-grid supply

    Orbital utilise the EC91 ATEX oxygen analyser from Systech Illinois to accurately monitor the oxygen content in the purified bio-methane gas prior to it being injected into the national grid gas network In September 2010, Orbital installed the gas monitoring and treatment plant on the UK’s very first large-scale bio-methane-to-grid production facility. This site was designed specifically to ...

  • Coal Bed Methane - A Global Market Scenario

    Coal Bed Methane (CBM) is a type of natural gas that is commonly extracted from coal beds located at depths between 300 to 1000 metres. This gas is an odorless, colorless mixture of a variety of gases, but with major share of methane – even upto 95% in many cases.  Browse: Coal Bed Methane ...


  • Modelling methane and vinyl chloride in soil surrounding landfills

    Sanitary landfilling is used in many countries as a preferred method for disposal of household wastes for reasons of simplicity and economics. Immediately following its deposition within a landfill, most of the organic fraction of waste will begin to undergo degradation through chemical and bacterial action. Landfill gas (LFG) is a product of biodegradation and consists of primarily methane ...

  • Analysis of availability and accessibility of hydrogen production: An approach to a sustainable energy system using methane hydrate resources

    It is considered that use of hydrogen as an energy source may contribute to environmental improvement and provide an alternative energy system. Moreover, it is anticipated that hydrogen will be in great demand in the near future for use in such vehicles as fuel cell-based cars. Research and development of a number of advanced methods of hydrogen production (OTEC, water photolysis using a ...

  • Solid thickening and methane production of livestock wastewater using dissolved carbon dioxide flotation

    Dilute manure is classified as wastewater due to the large quantity of water used in livestock production in Korea. Livestock wastewater treatment is required in order to reduce high moisture content and treat fluids discharged from the digestion process. In livestock wastewater treatment plants, large quantities of CO2 gas are produced at combined heat and power facilities as well as in the ...

  • Effects of the incorporation of drinking water sludge on the anaerobic digestion of domestic wastewater sludge for methane production

    Water purification and wastewater treatment generate sludge, which must be adequately handled to prevent detrimental effects to the environment and public health. In this study, we examined the influence of the application of settled sludge from a drinking water treatment plant (SDWTP) on the anaerobic digestion (AD) of the thickened primary sludge from a municipal wastewater ...

  • 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 ...

  • 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 ...
