Biogas analyzer for waste management and recycling

Biogas is exhausted from biological degradation of organic matter without oxygen. This gas is naturally emitted in swamps, landfills, etc. It is artificially produced as well for waste management – waste water, sewage and any organic waste treatment – to produce energy.

Biogas analyzer for waste management and recycling

Biogas production – through plants or digesters – and recycling are encouraged, however biogas remains a factor of global warming. This production, treatment and valorization processes thus require appropriate control and follow-up with biogas monitoring devices. In power plants, treatment and production centers, fixed and/or portable biogas analyzers for worker’s safety are required.

  • Biogas composition and effects on health

    Biogas is composed of several gases with different properties. Amongst them is methane (CH4) – primary gas that composes biogas from 50 to 70% - which is a combustible gas particularly used in power plants (gas turbine). Biogas is also composed of hydrogen sulfide (H2S) – a toxic gas – and carbon dioxide (CO2) – which is an asphyxiating gas – and water vapors (H2O) as well.
     
    As it is mainly composed of methane, biogas is above all a combustible and flammable gas. Because of the presence of hydrogen sulfide, it is also toxic and corrosive. Anaerobic fermentation also implies bacteria and particles that can cause disturbances to humans. Because of that, biogas presence has to be constantly measured and monitored - usually with a biogas analyzer.
     
    Short exposure to high concentrations does not lead to death. Symptoms of this exposure type are breathing tracts and eye irritation. In case of chronic exposure, organ failure can impact the digestive system (abdominal pain) and the brain (chronic tiredness).

  • Effects on health :

    As it is mainly composed by methane, the biogas is a combustible gas. It is also toxic and corrosive because of the presence of hydrogene sulphide.
    The anaerobic fermentation fermentation also produce bacteria and suspended particles that can cause disturbances to humans.

    A brief exposure to high concentrations does not lead to death. The symptoms linked to this kind of exposure are an irritation of the respiratory tracts and eye conjunctivitis).
    In case of chronic exposure, some organ failures such as the digestive system (abdominal pain) and the brain (chronic fatigue) have been observed. Thus the use of gas detection devices like a biogas analyzer and wearing the proper respiratory protection equipment is essential.

  • Biogas detectors and analyzers :

    Biogas analyzer (fixed or portable)

    Biogas is appropriate for cogeneration, which means a combined production of heat and electricity. As their properties can vary, gas turbines will need to adapt to biogas composition. A biogas analyzer (fixed or portable) measures and controls this gas quality for optimal performance.

    Biogas detector and area gas monitor

    Because of the different gases included in the composition of biogas, the most commonly used personal protective equipment (PPE) is a 4 gas detector (CH4, O2, CO & H2S). Nevertheless, using a multi-gas detector with CH4, O2, CO, CO2 and H2S sensors is more relevant. In addition to portable gas detectors, area gas monitors will ensure monitoring on the full production zone.

The Ventis-MX4 is a portable multigas detector. Contrary to single-gas detectors, it can detect up to 4 gases. Thanks to its rechargeable Li-ion battery, it can continuously operate during around 12 hours at 20°C ambient temperature. This battery can be replaced by an optional extended battery for up to 20 hours of autonomy without pump.

The Ventis-MX4 portable gas detector can detect up to 4 gases amongst explosive gases, oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2) and nitrogen dioxide (NO2). A specific location is dedicated to the explo sensor (catalytic sensor) and the oxygen sensor (electrochemical sensor). A 4 gas unit will basically include oxygen and explo sensors.

The Ventis-MX4 features 3 different alarms. The first one is a powerful 95 dB at 30 cm audible alarm to alert in noisy environmets. A high visibility red LED visual alarm and an ultra- vibrating alarm are added to improve safety. Two alarm levels are configures: low and high alarms – which are basically calibrated under occupational safety at work data.

The Ventis-MX4 portable gas detector also features the same physical properties – dimension and weight – than a single-gas detector. It can be wore close to the breathing tracts thanks to its crocodile clip without disturbing the user. This multigas detector shock-resistant and waterproof thanks to its high visibility polycarbonate-made overmold.

As this device can detect explosive gases, it meets current EU ATEX standards (explosive atmosphere). A sampling pump – VSP for Ventis-MX4 – is available to draw remote samples (up to 30 meters) before interventions – e.g. in confined space.

The Ventis Pro5 multi gas detector was especially designed to silmutaneously detect up to 5 gases among the combustible gases, NH3, CO, CO/H2S, H2S HCN, NO2, O2, SO2, CO2 and HC.

 

This flexible detector features a panic button to alert nearby teams when user is in distress. It also features a mandown alert function which is set to activate after a defined period of time without motion.

 

In case of anormal concentrations, powerful audible (95 dB à 10 cm) and visual (ultra-bright blue and red lights) alarms will alert any operator working in the area, even in high-noise and dark environments.

Custom alarm action messages like “EVACUATE” or “VENTILATE” can furthermore be configured in case of emergency situations in order to safely and quickly take corrective actions.

 

Made of polycarbonate with protective rubber overmold, this gas detector is available either in black or high-visibility safety orange versions and can be combined with the VSP slide-on pump. Its integrated data logger can record up to 3 months of events. Water and dust-resistant (IP68), the Ventis Pro5 can be used in pumped version for use in confined spaces or without pump as a personal protective equipment.

 

The Ventis Pro5 portable multi gas detector also features the LENS Wireless technology. LENS is the first wireless gas detection solution that allows personal monitors and area monitors to communicate gas readings and alarms with one another. This way, panic and mandown alarms will be communicated to other Ventos Pro detectors operating in the same area in order to alert everyone on the hazardous situations.

 

Lastly, the Ventis Pro5 benefits from the iAssign® technology for site and user follow-up. Thanks to this enhanced technology, every data recorded by the device will be assigned to the user ID. This process allows amongst other things users to wear several gas detectors within the same working day.
