  • The DMT Carborex® MS Small scale biogas upgrading plant

    Introduction As we are all aware, fossil fuels are depleting rapidly and the energy consumption is growing. Due to increasing fossil fuel prices other types of fuels become more interesting. Nowadays technology enables us to use renewable fuels in an economically profitable way. An easy technique to produce fuel is the digestion of green waste; sewage sludge, manure and agricultural ...

  • Small scale biogas upgrading: Green gas with the DMT Carborex® MS system

    Abstract  More and more effort is being put in the utilization of bio-solids. Bio-solids can be an important source for useful products like fertilizers and biogas. DMT has been developing biogas treatment plants for over 20 years following the market developments closely.  Biogas was first seen as a nuisance at e.g. landfills, creating odor problems and methane emissions. A flare has ...

  • Focus on Biogas Plants

    To meet the domestic fuel and bio-fertilizer needs, 3,680 biogas plants are planned to be set up in rural areas by June 2012, according to Pakistan Centre for Renewable Technologies. The Centre says that over 2,100 family-size biogas plants — against the target of 2,500 — have already been set up throughout the country. The programme, supported by NGOs, farmers’ bodies and the ...

  • Biogas in Asia

    The development of biogas production and monitoring has had many twists and turns, from its early days in Germany to the heady days of support through the Clean Development Mechanism (CDM).   The fall in the price of carbon credits, which rewarded reduction in emissions of methane (CH4) - a potent greenhouse gas - and use of methane from waste as renewable energy, has hit Asia ...

  • Anaerobic digestion foaming in full-scale biogas plants: a survey on causes and solutions

    Anaerobic digestion foaming is a common operation problem in biogas plants with negative impacts on the biogas plants economy and environment. A survey of 16 Danish full-scale biogas plants on foaming problems revealed that most of them had experienced foaming in their processes up to three times per year. Foaming incidents often lasted from one day to three weeks, causing 20–50% ...

  • CHP efficiency for biogas

    Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to ...

  • The Benefits of Biogas Conditioning

    Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

  • Determination of appropriate operational parameters of a floating–drum biogas plant for rural Nigeria

    This paper determined the appropriate operational parameters of a floating–drum biogas plant that give the highest gas production rate (m³/h), best gas quality (% methane fraction) and required output pressure (mbar) for burners. The operational parameters were retention time and weight on the floating drum of the plant. The retention times of 15, 20, 25, and 30 days, and weights of 50, 100, 150 ...

  • Above all, biogas must be efficient

    Herning Bioenergi and Bigadan use blower technology made by AERZEN In Denmark, AERZEN blowers create the link between biogas plant and dairy plant. Until 2020 Denmark wants to reduce its gross energy consumption - regardless of the aspired economic growth - by 12% compared with 2006. Another goal: Until 2050 the own power and heat requirements shall exclusively be served by ...

  • What`s New? Biogas Power

    Technologies that connect the biogas line to the power line include cooling and clean up components, microturbines and reciprocating gas engines and control systems. TOP BILLING on the biogas to electricity stage typically goes to the microturbines and reciprocating gas engines. But in the theater of renewable energy from organics recycling, the show can’t go on without the supporting cast of gas ...

  • Easy payback from biogas monitoring

    There is a strong business case for biogas monitoring and CHP protection. A fixed biogas analyser may cost some £6-10,000 and monitor gas every few minutes day and night. By comparison it can save its own cost many times over by protecting CHP engines from expensive unplanned downtime, biogas engine ...

  • Ethanol by-product raises biogas output

    In 2007, the City of Fergus Falls, Minnesota undertook a study to evaluate adding thick corn stillage to the anaerobic digesters at its wastewater treatment plant (WWTP). The goal was to determine the potential for codigesting syrup with biosolids to increase biogas production, while avoiding operational and regulatory problems. The Fergus Falls WWTP operates three digesters in series, two ...
