 Hi, welcome to Oizom Academy. Let's begin with all you need to know about methane. Methane is a colourless, odourless, tasteless, non-toxic gas composed of one carbon and four hydrogen atoms. It is highly flammable at very high concentrations of about 50,000 ppm. Methane is the second most important greenhouse gas. It is 28 times more potent than carbon dioxide at trapping the sun's heat into the atmosphere. However, it has an atmospheric lifetime of around 12 years much shorter than carbon dioxide. It is produced by the decomposition of organic matter in absence of oxygen by microorganisms called methanogens. It is naturally present under the ground or underwater and is a major component of natural gas. Natural sources of methane emissions are wetlands, swamps, marshes and water bodies. Other sources of methane include extraction of fossil fuels such as coal, oil and natural gas, biomass burning, mining, agricultural activities, livestock farming, landfill sites, sewage treatment plants and from power generation, specifically coal-fired power plants. Methane displaces oxygen causing asphyxiation at high concentrations. High level exposure may cause suffocation, loss of consciousness, headache and business, nausea, slurred speech, mood changes, vision problems and so on. In severe cases it may also cause rapid breathing, loss of coordination and numbness. Long term exposure lead to coma and death. Methane is highly efficient in trapping heat, making it a major contributor to global warming. It is a major precursor of another greenhouse gas, carbon dioxide. While converting to carbon dioxide, it releases other harmful air pollutants such as volatile organic compounds and ozone. Methane monitoring is an efficient way to detect the buildup of methane levels and take necessary actions. Different working principles for methane monitoring in the ambient environment are flame ionization detection, semiconductor, electrochemistry and non-dispersive infrared absorption or NDIR. At OISOM we measure methane sensor works on principle of NDIR where the infrared radiation of a specific frequency is absorbed by the methane molecules present in the gas sample and measured by the detector. OISOM's Odosense is a real-time odor emission tracking solution. It continuously detects, measures and monitors the odorful gaseous contaminants including methane, H2S, ammonia, sulphur dioxide, methyl macaptan, TVOCs and formaldehyde. Also Odosense measures weather parameters like temperature, humidity, wind speed and wind direction. Odosense is a proactive approach to measure real-time odor emissions. Odosense makes it an ideal choice for landfill sites, waste water treatment facilities, fertilizers, paper pulp industries and soil treatment sites. With this, I hope you now know all about methane.
