Monitoring of greenhouse gases to optimize the energy balance efficiency of biogas plants
2014.04.09_MARLIS HRAD_KLIMONEFF_4.as_ne_2020_Endbericht_Februar 2014Greenhouse gas emissions and methane losses(= loss of resources) can arise from diverse parts of biogas facilities along the entire process chain of biogas generation and utilization. Certain plant components (e.g., fermenter area (open effluent mounts), membrane, safety valves) are suspected as the greatest emitters. However, up to now, there are no authoritative data records available in order to evaluate the relevance of these losses and emissions demonstrating the actual (energy) plant efficiency. In addition there is no practically applicable and reliable quantification tool available for determining these emitted gas loads and losses. Hence, the aim of this project is to create a representative data pool and to develop simultaneously a simply applicable monitoring and quantification tool for quality cotrol and quality management of biogas plants. Significant evaluation parameters are the representation of the greenhouse gas emissions of the entire plant and methan losses (methane loads) from various plant components (fermenter area (open effluent mounts), gas tank, pipework, safety armatures, gas engine, etc).
An improvement and optimization of various plant components and, therefore, an increase in efficienncy of the entire biogas plant can not be achieved until the losses are quantified.
The data- pool will be generated by the use of open- path concentration measurements in combination with meteorological measurements and a dispersion model for a representative period of more than one year, taking into account seasonal, daily and meteorological variations as well as plant- specific changes.
Subsequently, a practise- oriented catalogue of measures based on the gained data pool will be developed indicating optimization potentials and solution approaches (technical, operational, biotechnological) concerning an increase in efficiency of gas yield and minimization potentials of gas losses.
The outcome of the project will provide a monitoring and quality management tool for biogas plants as well as a better decision basis for the optimization of facilities and operation as well as political- strategical developments within the framework of the Austrian energy and climate policy.
