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 ...

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 ...

Precise biogas flow measurement: Overcoming the challenges of changing gas composition
INTRODUCTION As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. The production of biogas is ...

Biogas purification in EDAR Mapocho - Case Study
BIOCONSERVACION: Integral solution for biogas purification in WWTPs Biogas is mainly composed by methane and carbon dioxide as a result of organic matter fermentation in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of biogas depends entirely on the nature of the waste processed and the conditions under which takes place the anaerobic ...

Biogas desulphurisation using the DMT multiple stage Sulfurex® process
Global rising energy costs are focusing efforts by many industrial and municipal entities to find new sources of energy. Generating electricity from Biogas is of course nothing new however the cost of cleaning up certain Biogas streams with excessive levels of Hydrogen Sulphide (H2S) has previously proven to be financially unsustainable. Rising energy costs combined with improvements and cost ...

Biogas Cleaning
Removal of water vapor Origin In the biogas production process, water is an intrinsic part of both the material to be digested (biomass) and the process itself. Furthermore, water is the medium in which biogas production takes place, regardless of whether the digestion process is dry or wet, the biogas produced will contain water vapour. The amount of water vapour contained in the biogas ...

Project - Biogas purification at Mapocho WWTP
Biogas is a mixture of gases, the main components of which are methane and carbon dioxide, produced as a result of the fermentation of organic matter in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of the biogas depends entirely on the nature of the waste used and the conditions under which anaerobic digestion is carried out. Generally, the ...

Biogas measurement devices
As global oil prices remain high, countries around the globe are seeking renewable energy sources to increase energy efficiency and security. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas. To monetize biogas and create the most efficient fuel sources, it is critical to accurately measure how much biogas is produced in each stage of the ...

Biogas Treatment in WWTP
Wastewater treatment plants (WWTPs) are facilities that consume large amounts of energy (thermal and electrical), as a result of their operation, they produce large amounts of sludge. The anaerobic digestion of these sludges from wastewater treatment produces biogas, which, due to its concentration in methane (CH 4 ), constitutes a biofuel that can be used for energy production. The best ...

Biogas desulphurisation in the WWTP do Norte (Portugal) - Case Study
The Northern Wastewater Treatment Plant (WWTP) is one of the biggest in the central region of Portugal, servicing various municipalities. The infrastructure is located in the area of Coimbra, Leiria, taking up 6 hectares of land; it receives effluents from some 250,000 inhabitants across multiple municipalities. It has the capacity to treat around 38,000m3 of wastewater on a daily basis, 77% of ...

Desulfuration of Biogas
ORIGIN, EFFECTS AND TREATMENTS The elimination of hydrogen sulfide (H2S) in biogas becomes a necessity not only to keep the pipelines, machines and equipment involved in its transportation, use and application in good condition but also, and above all, to preserve the life of all the personnel in charge of the operation and maintenance of the biogas production stations, as well as ...
