Biogas Monitoring Applications

  • Agitators for Biogas Blants

    Use the SUMA agitators to prevent the formation of floating and sinking substrate layers. Furthermore they ensure that the substrate maintains an equal temperature throughout. The homogeneously distribution of nutrients for the biological process enables more efficient gas flow out of the substrate.

    Biogas Monitoring for the Renewable Energy Industry

    AppliTek`s solutions in this field concentrate on the process efficiency of anaerobic digesters. Many existing digesters give unnecessary problems, which arise due to inadequacies in the process or process control system. AppliTek has developed a unique instrument to measure and control the key processes in the anaerobic fermentation. Compact gas analyzers with proprietary technology can be implemented to check the biogas yield.

    Parameters: Volatile Fatty Acids - Alkalinity - pH - Bicarbonate

    Gas parameters: CH4 - CO2 - O2 - H2S

  • Beverage Analysis

    Hiden gas analysis systems provide for high sensitivity, wide dynamic range, real-time analysis of almost any gas/vapour. Hiden’s application specific gas analysis systems are tailored to meet the specific application requirements, & include a range of special sampling, vacuum pumping and vacuum accessories. Hot zone sampling accessories are included for evolved gas analysis from furnaces, & thermo gravimetric analysers, TGA, for example. Thermal analysis methods are vital for catalysis characterization. For thermal analysis including TPD/TPO/TPR studies, Hiden gas analysis systems include enhanced pumping for hydrogen and special close coupled sampling to the TPD/TPO/TPR reactor for optimum thermal analysis response. In Biogas applications the simultaneous analysis of H2S, CO2, water vapour & CH4 in the PPM to 100% concentration range provides vital information for process development and process monitoring

  • Biogas monitoring

    meet governmental regulations, it is important to accurately monitor methane gas production, removal, venting, and burning. Knowledge of both methane flow and temperature at the flare stack can define when CH4 is being emitted to the atmosphere. The DX99 FlexPower™ Nodes can be installed in EX area with a Zone 0 ATEX certification. Use the analogue input to determine methane production levels and flow and use the thermocouple model to measure the temperature of a vent to verify the continuous combustion of methane.

    Sensor for Biogas

    Anaerobic Digestion plants produce various gas components from a source material (or feedstock) that can be composed either solely or as a mixture of slurries, purpose-grown crops, food and organic waste material. The composition of the gas produced varies depending upon the feedstock and the Anaerobic digestion process itself. As a consequence, it is normal to measure various components of the resultant gas produced to evaluate the efficiency of the Anaerobic Digestion process. Furthermore, due to the flammable nature of Methane (CH4), and the risk of asphyxiation, most plants feature ambient air monitoring to protect personnel from any unplanned accumulation of leaked gas. CH4 is the gas component fuel, which is the intended end product of the anaerobic digestion process. In biogas plants, the concentration of CH4 in a working plant varies between 50%-75%, which is well above the Upper Explosive Limit (UEL).

    Gas analysis & monitoring system for biogas analysis

    “Biogas” means a mixture of various types of gas (mostly methane) produced by bacterial fermentation in anaerobic conditions(absence of oxygen) of organic residues from waste, decaying plant, carcasses in putrescence. The analyzers of biogas by Infrared cells carry out the continuous analysis of CH4, O2, CO2, H2S and NH3. The whole process sees the decomposition of organic material by some types of bacteria, producing carbon dioxide, molecular hydrogen and methane(methane conversion of organic compounds).

    Measurement solution for siloxane measurement in land-fill gas via FTIR

    What are siloxanes?

    The generation of electricity from municipal digesters and land fill is of increasing interest, as the biogas generated is a form of renewable energy. Organosilicon compounds are often present in products such as shampoo and cosmetics, as well as industrial products and lubricants, and they move into land-fill. These volatile compounds find their way into land-fill or digester gases as siloxanes.
