  • Biogas-to-biomethane upgrading plant

    Chesterfield BioGas (CBG) supplied the UK’s first biogas upgrading plant to produce clean biomethane for direct injection into the national gas grid for use by all consumers. The project was successfully completed and gas injected into the national grid at the wastewater treatment site of Thames Water site at Didcot, Oxfordshire in October 2010. This achievement was a benchmark moment for ...

  • Biogas upgrading using the DMT Carborex® PWS Technology.

    Abstract Gas is an excellent fuel for a large number of applications and can also be used as raw material for the pro- duction of chemicals. Biogas can be used in more or less all the applications that are developed for natural gas. For some of the applications biogas may have to be upgraded. Injection of biogas into the natural gas grid will result in an improved security of supply. This ...

  • Biogas upgrading to green gas and vehicle fuel

  • Biogas upgrading: Membrane separation takes over

    Abstract Due to governmental incentives and growing environmental awareness, it becomes increasingly attractive to upgrade biogas to natural gas quality and inject it into the natural gas grid or to use it as transport fuel. In this way, the biomethane can be utilized with the highest energy efficiency. Progressively, effort is being put into the utilization of organic waste streams in ...

  • Next generation biogas upgrading using highly selective gas separation membranes

    More and more effort is being put into the utilization of organic waste streams in anaerobic digesters, producing useful products such as fertilizers and biogas. DMT has been developing biogas treatment plants for over 25 years, closely following market developments. It is becoming increasingly attractive to upgrade biogas to natural gas quality and inject it into the natural gas grid or use it ...

  • 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 ...

  • Biogas desulfurization and biogas upgrading using a hybrid membrane system – modeling study

    Membrane gas permeation using glassy membranes proved to be a suitable method for biogas upgrading and natural gas substitute production on account of low energy consumption and high compactness. Glassy membranes are very effective in the separation of bulk carbon dioxide and water from a methane-containing stream. However, the content of hydrogen sulfide can be lowered only partially. This work ...

  • 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 ...

  • Autogenerative high pressure digestion: anaerobic digestion and biogas upgrading in a single step reactor system

    Conventional anaerobic digestion is a widely applied technology to produce biogas from organic wastes and residues. The biogas calorific value depends on the CH4 content which generally ranges between 55 and 65%. Biogas upgrading to so-called ‘green gas’, with natural gas quality, generally proceeds with add-on technologies, applicable only for biogas flows >100 m3/h. In the concept of ...

  • Evaluation of the simultaneous biogas upgrading and treatment of centrates in a high-rate algal pond through C, N and P mass balances

    The simultaneous capture of CO2 from biogas and removal of carbon and nutrients from diluted centrates in a 180 L high-rate algal pond (HRAP) interconnected to a 2.5 L absorption column were evaluated using a C, N and P mass balance approach. The experimental set-up was operated indoors at 75 μE/m2·s for 24 h/d at 20 days of hydraulic retention time for 2 months of steady ...

  • Making pressurized water scrubbing the ultimate biogas upgrading technology with the DMT Carborex® PWS system.

    Abstract Biogas is one of the most promising energy sources for the future. Biogas is a “waste” product from e.g. landfill sites or digesters that can be applied as a green and renewable energy source with no global emissions on CO2 and hardly no local emissions on other pollutants. Currently most biogas is used at a CHP at which a large part of the energy ...

  • From the biogas to vehicle fuel

    The biogas consists mainly of methane and carbon dioxide. Other components can be water and sulphur, mainlyhydrogen sulphide. To be able to use the biogas as vehicle fuel or to distribute it in natural gas grids the gas has to becleaned and upgraded. The biogas is upgraded by removing carbon dioxide to raise the calorific value and create a gaswith constant quality. One of the techniques to ...

  • Case study - Upgrading highly loaded waste ponds to “Bio-Gas Banks”

    Problem: Un-covered anaerobic systems can generate significant amounts of odors and renewable energy in the form of methane. The sulfides and methane are lost to the atmosphere due to lack of an impermeable barrier. If the basins were covered, the biogas could be captured, burned and converted to electricity and odors contained. A Missouri project, believed to be the largest and most ...

  • High-strength wastes boost biogas production

    Water and wastewater treatment plants (WWTP) are significant consumers of energy. The U.S. Environmental Protection Agency estimates the industry uses the equivalent of 56 billion kilowatt hours (kWh) of electricity, representing three percent of the nation’s energy consumption, and is responsible for creating 45 million tons of greenhouse gas emissions each year. Energy intensive processes, such ...
