  • Fast, simultaneous and continuous monitoring of NOx and NH3 in DeNOx applications

    In DeNOx systems using urea injection with ammonia (NH3) as a reducing agent, the flow rate and control of NH3 must be continuously adjusted and controlled to prevent excess NH3 emissions (slip), to reduce environmental impact and cost of reagents. To optimize this process, it is essential to use an emissions analysis system for simultaneous and continuous monitoring of NOx and NH3. For preparing ...

  • Warehouse Optimization: Balancing Equipment Performance and Worker Safety Through Emissions Measurements and Air Quality Monitoring

    Successful warehouse functionality is dependent on both maximizing equipment performance and providing a safe and healthy environment for workers that encourages productivity. However, these two factors are often at odds with each other as warehouse equipment such as forklifts, burnishers and delivery trucks emit toxic gases that can have the potential to create poor indoor air quality which ...

  • WESPS continue to deliver

    Compliance with the increasingly stringent air pollution regulations of recent years is not the only reason forwardthinking industry leaders are adopting more sophisticated gas cleaning and air pollution control strategies. The desire to achieve higher performance efficiencies, control costs in a competitive marketplace, and stay ahead of the regulatory compliance curve is another driver of ...

  • Impacts of Federal Tax Credit Extensions on Renewable Deployment and Power Sector Emissions

    Executive Summary Federal tax credits for renewable energy (RE) have served as one of the primary financial incentives for RE deployment over the last two decades in the United States. In December 2015, RE tax credits, including the wind power production tax credit and solar investment tax credits, were extended as part of the Consolidated Appropriations Act of 2016. The act extended the ...

  • Gas Detection and Monitoring Systems

    In greenhouse applications, the accurate measurement of a number of environmental parameters such as carbon dioxide concentration, temperature, light intensity, water, humidity, pH and nutrient levels using sophisticated sensors is used to create a controlled environment for optimising plant growth rates while minimising energy usage. Carbon dioxide concentration is also one of the best ...

  • Successful reduction of diffuse nitrogen emissions at catchment scale: example from the pilot River Odense, Denmark

    Land-based total nitrogen (N) loadings to Danish coastal waters have been markedly reduced since 2000. This has been achieved by general measures reducing discharges from all point sources and N leaching from farmed land supplemented with more local and targeted mitigation measures such as restoration of wetlands to increase the catchment-specific N retention. In the catchment of River Odense, ...

  • Modelling emissions of perfluorinated chemicals to the Danube River Basin

    The emissions of two perfluoroalkyl acids (PFAAs) into the Danube River Basin have been estimated in a test of four different hypotheses regarding the factors affecting those emissions. The results were used to simulate water concentrations for comparison with measured data. The researchers found that incorporating wastewater treatment information and wealth distribution alongside population data ...

  • Delaying substantial emission reductions limits climate policy choices

    If fast and substantial reduction in greenhouse gas emissions is postponed further, there are fewer options available to stay below the 2 °C warming target for the end of the century. Delayed action is likely to require measures that remove CO2 from the atmosphere by planting forests and using bioenergy in combination with carbon capture and storage. The latter technique ...

  • Global growth in CO2 emissions almost stalled in 2014

    In 2014, the growth in global CO2 emissions from fossil fuel use and cement production slowed down to only 0.5% compared to 2013, while the world’s economy grew by 3%, showing a partial decoupling of CO2 emissions and economic growth. China and the United States increased their emissions by 0.9%. In the European Union, CO2 emissions decreased by an ...
