Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM). The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG. As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat. Landfills and mines represent two of the most abundant sources, however reports indicate that more than...
Production of aluminum from its ores at aluminum smelters results in carbon dioxide CO2, carbon monoxide CO, sulfur dioxide SO2, and hydrogen fluoride HF gas emissions during the electrolytic process phase to the atmosphere. The gas emissions need to be monitored. Typically the smelters have emission limit values (ELVs) for sulfur dioxide and hydrogen fluoride emissions. These emissions should be measured accurately and with good precision, to ensure the smelter does not exceed its emission limit values. In...
Precise measurement of natural gas requires high accuracy, low pressure drop and direct mass flow reading—all the hallmarks of Sierra’s immersible thermal, mass vortex and thermal mass flow controllers. Our mass flow controllers are ideal for natural gas flow measurement with 100:1 turndown and no moving parts, providing a robust MFC solution. Our natural gas flow measurement instruments can also handle liquefied natural gas (LNG) via our cryogenic mass vortex meters.
Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of...
Monitoring Sulfur Hexafluoride (SF6) in the Power Utility Industry.
Monitoring Sulfur Hexafluoride in the Power Utility Industry
The SF6 Leak Detector 3434i from LumaSense offers an unmatched combination of performance and convenience. Based on the company’s Photoacoustic Spectroscopy (PAS) technology, the system offers highly accurate, reliable and stable quantitative gas analysis and detection. The growing environmental requirements and pressures regarding the use of SF6 make LumaSense’s system a coveted tool...
The TunnelTech 200 series are primarily gas monitors with optional Visibility capability. Most use Infra-red absorption technology to monitor gaseous pollutants and those with a visibility channel use optical attenuation for that application. All TunnelTech 200 analysers except the TunnelTech 205 use the same rugged corrosion resistant enclosures and have an optional Data Display unit. As there is only one moving part so reliability levels are very high and maintenance levels very low.
With its expertise in calculating and managing emissions data, CERC offers a range of services to assess greenhouse gas emissions, from determining the carbon footprint of a single industrial process, to compiling a greenhouse gas inventory for a whole geographical area.
CERC uses methods and emission factors laid out by the Intergovernmental Panel on Climate Change (IPCC). Emissions from transport, industrial, heating and agricultural activities are calculated and stored using the EMIT software package.
Application: In March 1986 an explosion destroyed a bungalow adjacent to a landfill site in Loscoe, Derbyshire. Subsequent measurements showed that 150-200 cubic meters of gas per hour were being generated by landfill waste. This event triggered a change in the way the waste industry considered and regulated gas generated at landfill sites; resulting in the landfill regulations of 2002, and in particular LFTGN03: the Guidance on the Management of landfill Gas.
Our world economy is only 9.1% circular, leaving a massive Circularity Gap. This is an alarming United Nations statistic from the global Circularity Gap Report. Released this year, the Circularity Gap Report provides data and a framework for measuring and monitoring progress in bridging this gap, year by year. Tracking and targeting performance via the Global Circularity Metric helps us engage in uniform goal-setting and guides future action toward the greatest impacts.
based in Leinfelden-Echterdingen, GERMANY.
In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time.
SF6 (sulphur hexafluoride ) or air is used as an insulation gas in circuit breakers . Excess moisture in these gases causes arcing, which can trip the circuit breaker and cut off power to the distribution network. More seriously, such arcing can lead to physical damage of equipment and, on occasion, death of plant operatives (please ask for our case study on circuit breakers).
Measurement of particulates, SO2, NOX, CO, hydrocarbons and greenhouse gas emissions from the mineral process industries requires careful selection of instrumentation. Ecotech offers a complete monitoring solution tailored to this industry.
Closed chamber gas flux measurements can be made with Protea FTIR analysers to allow researchers in the field of atmospheric gas analysis from agricultural and livestock to measure evolved gases such as N2O, CO2, CO, NH3, and CH4. Nitrous oxide (N2O) and Methane (CH4) emissions from soil, plant and livestock are especially important gases to measure, given their high potential as greenhouse gases (GHGs). NH3, whilst not a greenhouse gas on the scale of N2O, CH4 and CO2, is a major emission from agricultural, such...
Petrochemical plants, and especially their process water recovery plants, are a major source of air pollution. If odours are a recurring problem, the emission of greenhouse gases may also be particularly important.
Hydrocarbons are a family of organic chemicals consisting of carbon and hydrogen atoms arranged in a variety of ways. Hydrocarbons are found naturally in crude oil and are released into the environment with its combustion (power plants, home heaters etc).
The aluminium industry is the major source of perflurocarbon (PFC) emissions to the atmosphere, which are a major contributor to global warming. PFCs have greenhouse gas effects up to 10000 times that of CO2. Emissions have been reduced over the last 20 years, but further reductions are harder to achieve as all the mechanisms for PFC production are not known. In order to better understand the production of PFC on an industrial level, laboratory studies have been carried out using a small scale cell.
