  • Measuring carbon in steel – absolute reliability matters

    The incorrect analysis of the carbon content in steel can lead to a multitude of issues down the line, making accurate and reliable carbon analysis critical. Our OES expert Willy Sanders looks at why… Carbon steel has been in use for nearly 2,000 years, but rose to prominence during the late industrial revolution when steel makers really began to exploit the properties that a little carbon ...

  • Emissions analyser helps manage power station

    A multiparameter emissions monitor at Thetford power station is being used to demonstrate to the Environment Agency that the plant is performing within the conditions of its environmental permit. However, the data from the analyser, which was supplied by Milton Keynes based Quantitech, also performs a vitally important role in helping to manage the plant. “Individual gas readings are ...

  • Game theoretic analyses of nitrate emission reduction strategies in the Rhine river basin

    Pollution of transboundary rivers requires cooperation between the countries involved in order to alleviate the consequences. This paper applies game theoretic analyses to nitrate emissions in the Rhine river basin. It assumes that the 50% emission reduction policy agreed upon by the International Rhine Committee is individually rational for each source. This enables the estimation of a revealed ...

  • Analysing the effects on the atmosphere of exergy changes due to exhaust-gas emissions

    The exergy change of the surroundings of exhaust-gas emitting ports, and its probable effects on the atmosphere, are investigated and the current stable state changing point of the atmosphere is determined. The potential for doing work is described and the effects of the amount of exhaust gas on the atmosphere are studied through calculation and analysis of an exergy-change function, which is ...

  • Model analyses of long and short term pollution emission reduction

    Climate change is influenced not only by the emissions of greenhouse gases, but also by the emissions of air pollutants which influence each other through complex interactions in the atmosphere. Reducing emissions could be one way to react and prevent negative impacts from climate change. Because these reductions must take place in the face of economic growth, there is a disagreement about the ...

  • Gas Analyser Unit

    Gas Analysers are used in several industries, chemical industries in particualr use gas analysers to monitor their gas emission levels, air quality samples are compared to high purity reference gases to analyse and measure the emissions.  A common practice is to “calibrate” the sample air against clean, dry pure reference gases such as H2, He, Ar, or N2. The ...

  • Popular analysers are portable and rentable

    The MCERTS approved HORIBA PG-250 has been one of the most popular  instruments in Ashtead Technology’s fleet of rental equipment for a number of  years. Jay Neermul, the company’s Environmental Product Manager says “This  is because it is able to analyse CO, NO/NOx, SO2 and CO2 using standard  reference methods in a portable instrument that can be easily and ...

  • How Does a Gas Analyser Work?

    Whatever you want to detect, you need to identify a property of the object that is easy-enough to measure. When it comes to monitoring and analysis of gaseous species (atoms or more commonly molecules), it turns out that it often is possible to utilize the optical properties of the gas. You need a light source, a light detector, and a characteristic behaviour of the gaseous species in question ...

  • Options to Reduce Methane Emissions

    This study analyses methane emissions in the EU and strategies to control them. It considers options for the reduction of emissions from each of the main source sectors, agriculture, waste, coal mining and the oil and gas industry, and assesses costs and applicability of the mitigation options available to produce cost curves for reducing emissions. The study also makes projections of methane ...

  • Substance flow analyses of phthalates and nonylphenols in stormwater

    The occurrence of nonylphenol and several phthalates in water environments is highly undesired because of their negative effects on aquatic organisms. The objectives of this study were to identify emission sources of phthalates, nonylphenol and its ethoxylates (NP/EOs) in urban stormwater, and to quantify the substance fluxes from the source to the stormwater system, using the methodology of ...

  • FTIR resolution requirements for industrial gas analyses

    FTIR Spectroscopy FTIR Spectroscopy is a widely used technique for gas analyses in industrial applications. It is a technique used in the semiconductor industry for measuring the purity of cleaning, etching, and epitreatment gases used with various process tools, reactors, and abatement devices. Among chemical companies and R&D faciltities, FTIR is applied to combustion ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Analyses of technical options for mitigating CO2 emissions from an urban transport system: a case study of Beijing City

    This paper aims to extrapolate the energy consumption and environmental emissions data on the urban passenger transport system in Beijing, to assess the cost-effectiveness and emission reduction potential of promising technology options for transport systems, and to identify options with both reduction potential and cost-effectiveness. Furthermore, it identifies major barriers to the adoption of ...

  • Should your company be conducting life cycle analyses?

    Many companies have already answered yes to that question – for a combination of reasons typically related to stakeholder interest, key customer demands, public perception, and competitive positioning.  In fact, life cycle analysis (LCA) has increasingly become an important tool in mature corporate sustainability programs, providing organizations with a consistent methodology for ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Static and dynamic instantaneous emission modelling

    Emission models can be categorised into three categories: average speed models; traffic situation models, used at macro-scale or meso-scale level (national, regional, city level); and instantaneous (modal) models, useful at micro-scale level (street, vehicle level). To improve the existing instantaneous emission models, some preconditions must be fulfilled: the emission signals should be measured ...

  • Who Needs Continuous Emissions Monitoring?

    Continuous emissions monitoring (CEM) is about monitoring air pollutants generated by a specific activity and emitted to the ambient air, typically through a tall stack or other exhaust pipe. The “activity” can be some industrial process like a power plant or a waste incinerator, but it can also be on a much smaller scale such as a car equipped with an internal-combustion engine. ...
