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 ...

Sydney Water – 5 x sewage gas cogeneration sites - Case Study
Clarke Energy have been contracted by Worley Parsons on behalf of Sydney Water to design, supply and commission the GE Jenbacher cogeneration engine package, with exhaust gas heat recovery. The engines use the sewage gas produced by the on-site digesters to produce renewable power. In turn the heat generated by the engines through the combustion will go back to the digesters, increasing gas ...

Background of biogas technology and its recent developments in Iran
Biogas activities have been initialised since the mid 1970s in Iran. Only a few of about 70 rural projects are still active. Other activities include four municipal landfill gas extraction projects through which, two projects are being ready for power generation and some anaerobic treatment plants in industrial food processing factories. A modern research plant for practical investigation on ...

How big is the distributed energy opportunity for water and wastewater utilities?
Energy costs for water utilities are large, and growing Energy is a significant cost for many water utilities, and costs are growing as more energy-intensive forms of water supply, including desalination, are being used. Energy is typically the second-largest utility budget item in developed countries, after labour. In many developing countries, energy can account for 70% or even more, of annual ...

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 ...

3 Explanations Why You Want a Carbonization Machine
Carbonizing meals are an ancient preservation technique that could store food for long periods. A carbonization machine uses dry heat to get rid of most moisture from foods, leaving these with very little water content. This method gives you more life expectancy so it helps maintain flavor!There are numerous machines on the market, but not all are created equal. These appliances vary in ...

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 ...
