Diagnosing the effects of pilot fuel quality on exergy terms in a biogas run dual fuel diesel engine
This work presents the exergy balances of biogas dual fuel combustion modes using two different pilot fuels in a single–cylinder diesel engine. The main focus is on the use of biodiesel (BD) as a pilot in place of fossil diesel fuel. The results reveal that the important exergy loss recovery sources are the exhaust gas and cooling water exergy. By accessing these losses, there is an increase of ...

Biogas cleaning / conditioning - A requirement for optimal functioning of CHP systems
Biogas is obtained through the anaerobic decomposition (putrefaction) of organic matter. It contains methane (CH4) in varying proportions, ranging from 35% to 70%, a proportion which largely depends on production methods and the materials involved in the process. This methane concentration is what enables biogas to be used as fuel. The release of methane into the atmosphere contributes to an ...

Sewage biogas fuels public transport buses in Oslo
Bimethane produced by the Bekkelaget sewage treatment plant in Oslo, Norway, will begin fueling B0 public sector buses in 2009, marking a major step towards meeting its goal to reduce climate gas emissions 50% by the year 2030. Another 250 buses will be fueled by biomethane produced from two wet-organic waste separation plants scheduled to start up in 2011. Norway signed the Kyoto Protocol, an ...

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 ...

Sulphasorb Fe - Adsorbent Media - Dairy Biogas Plant, California, USA - Case Study
THE PROBLEM: A dairy biogasfacility in California was undergoing needed upgrades and expansions. Biogas is a gaseous fuel produced by the fermentation of organic matter, most often in the form of bovine waste. This facility plays a vital role by breaking down organic matter and sourcing energy for the community. These processes release primarily methane, hydrogen sulfide (H2S), and carbon ...

Cow’s fueling cars
Biogas upgrading at the Hagelsrum farm Farmers who make biogas from manure are not uncommon, but the Birgersson family on Hagelsrum’s farm goes further than that. With four biogas fueling stations and a fifth one coming up, they are contributing to the circular economy and closing the circle from cow to fuel tank. At the Hagelsrum’s farm just outside the town of Målilla, 650 ...

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 ...

GTI’s cover for the town of Creston lasts 20 years - case study
The Town of Creston, British Columbia, Canada, operates an anaerobic digester to treat brewery wastewater. Biogas is used to fuel a boiler for process heating. The system was approaching 20 years old and the cover, originally built by GTI, required replacement. The anaerobic digester had to remain in service while the covers were changed. The cover was replaced with an updated GTI gas collection ...

How-to calculate the Acid Dew Point (ADP) of flue gas
When flue gas reaches a temperature below the acid dew point, acidic elements will condense. The acids that are formed are highly corrosive for heat exchangers. Knowing the acid dew point of your flue gas enables you to select the appropriate materials for your installation. What is the Acid Dew Point? The acid dew point of flue gas is the temperature at which ...

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 is ...
