  • 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 ...

  • Evaluation of thermal steam-explosion key operation factors to optimize biogas production from biological sludge

    Thermal steam-explosion is the most extended hydrolysis pretreatment to enhance anaerobic digestion of sludge. Thermal hydrolysis key parameters are temperature (T) and time (t), and the generally accepted values reported from full-scale information are: 150–230 °C and 20–60 min. This study assesses the influence of different temperature–time–flash combinations (110–180 °C, ...

  • 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 ...

  • Optimal environmental benefits of utilising alternative energy technologies in Jordan

    With rapid population growth and increase in industrial activities, more energy is consumed, resulting in environmental pollution and economic difficulties. Therefore, the need for utilising renewable energy resources has emerged. Although Jordan does not have adequate fuel supplies (90% of its crude oil is imported), it is gifted with alternative resources. Because of the political and ...

  • Effect of the solid content on biogas production from Jatropha curcas seed cake

    Anaerobic conversion of Jatropha curcas seed cake was studied in a five–litre working volume batch reactor at 30°C. Over a 60–day operating period, a slurry of seed cake in water at a 1 : 20 seed cake–to–water ratio showed the highest methane yield of 296 litre methane/kg Chemical Oxygen Demand (COD) degraded (or 156 litre/kg of Jatropha curcas seed cake added) and achieved 52% COD removal. The ...
