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 ...

Biohydrogen production from tequila vinasses using a fixed bed reactor
In Mexico, the industrial production of tequila leads to the discharge of more than 31.2 million of m3 of vinasse, which causes serious environmental issues because of its acidity, high organic load and the presence of recalcitrant compounds. The aim of this research was to study the feasibility of a fixed bed reactor for the production of biohydrogen by using tequila vinasse as substrate. The ...

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 state, ...

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 ...

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 waste from ...

No Pipeline for Renewable Natural Gas Projects? No problem. Use Virtual Pipeline Technology
On site biogas production Biogas can be produced from various organic resources of which the most common are agricultural waste, municipal waste, landfills, and wastewater treatment facilities. But biogas upgrading is also very much applicable in the (food & beverage) industry. Through biogas upgrading, trace impurities and carbon dioxide (CO2) in raw biogas are separated from methane (CH4) ...

Energy technologies for rural areas ? decentralised power generation through MARKAL modelling: a case study
Due to shortage of power, extremely subsidised tariffs, poor financial recovery, long transmission lines, there exists a very poor demand-supply balance in the rural energy sectors of India. MARKAL bases analysis of a village-group in western India reveals that there is a potential of reducing the electricity demand by about 18% as compared to the business-as-usual case through adopting energy ...

Portable biogas bottling plant: a practical approach for using biogas as transportation fuel in rural areas
Biogas contains about 65% methane, 30-35% carbon dioxide, traces of hydrogen sulphide and moisture. It has been observed that diesel engines get severely damaged when operated on biogas for long duration. Presence of these corrosive gases make biogas unsuitable for transportation application. By removing CO2 and trace acidic gases like H2S and moisture, biogas can be converted into natural gas ...

Increased biogas production in a wastewater treatment plant by anaerobic co-digestion of fruit and vegetable waste and sewer sludge – A full scale study
Anaerobic digestion is a well established technology for the reduction of organic matter and stabilization of wastewater. Biogas, a mixture of methane and carbon dioxide, is produced as a useful by-product of the process. Current solid waste management at the city of Prince George is focused on disposal of waste and not on energy recovery. Co-digestion of fresh fruit and vegetable waste with ...

Increasing methane content in biogas and simultaneous value added product recovery using microbial electrosynthesis
Electrosynthesis of multi-carbon compounds from the carbon dioxide present in biogas is a nascent approach towards purification of biogas. Microbial electrosynthesis (MES) cells, fabricated using different electrode materials, were operated using different electrolytes and mixed anaerobic culture as biocatalysts in the cathodic chamber under an applied cathode potential of −0.7 V vs standard ...

The Future of Biogas: Why Biogas Analyzers are Key to Advancements in Renewable Energy
As the world continues to shift towards sustainable energy sources, biogas is emerging as a valuable and versatile renewable energy option. Biogas is produced through the decomposition of organic matter, such as agricultural waste and sewage, and can be used to generate electricity, heat, and fuel. However, to get the most out of this resource, it is crucial to understand and monitor the quality ...

Biomethane enters the gas grid article for energy world
The Carbon Plan, published in 2011, aims to reduce UK carbon emissions by a quarter from 1990 levels. With the current policies in place, the UK is on target to reduce emissions by over a third by 2020 and with the introduction of new technologies this should increase to an 80% reduction by 2050. However, currently around half the UK’s carbon emissions result from heat related processes and ...
