  • Costs and benefits of agricultural ammonia emission

    Dec 17, 2019Background In Europe, ammonia (NH 3) emissions strongly contribute to fine particulate matter (PM2.5) pollution and associated premature human mortality. The National Emission Ceilings Directive 2016/2284/EU has set an obligation for all European Union countries to reduce the NH 3 emissions by 6%, relative to 2005, by 2020.Cited by: 6

  • Ammonia (NH3) emissions — European Environment Agency

    The majority of the reduction in emissions is due to the combination of reduced livestock numbers across Europe (especially cattle) and the lower use of nitrogenous fertilisers. NH 3 emissions have also declined in EEA-33 countries outside the European Union between 1990 and 2011.

  • Emissions Archives - NH3 Fuel Association

    NH3 is a carbon-free fuel, so it has the potential to reduce CO2 emission from the power plant when used as a fuel. However, NH3 has combustion characteristics different from conventional hydrocarbon fuels. The N atom in the ammonia molecule causes high NOx emission through combustion reactions.

  • Increasing Ammonia Concentrations Reduce the Effectiveness

    Atmospheric ammonia (NH3) plays a crucial role in the formation of secondary inorganic aerosols (SIAs). Although China produces a large amount of NH3 emissions, it has not yet taken any measures to control NH3 emissions. Satellite retrievals show that NH3 vertical column densities (VCDs) have obviously increased in recent years, by approximately 20% from 2011 to 2014, in contrast to the

  • Reducing NH3 Slip in Selective Catalytic Reduction (SCR

    SCR (Selective Catalytic Reduction) is a method to reduce NOx emissions by converting the NOx to Nitrogen (N 2) and water (H 2 0) by the reaction of NOx and Ammonia (NH 3). This reaction is sometimes referred to as De-NOx. The reaction between NOx and NH 3 is never perfect, although it can achieve efficiency rates often higher than 95%.

  • ACPD - SO2 and NH3 emissions enhance organosulfur

    Jan 22, 2021Our results suggest that strict control of SO 2 and NH 3 emissions might remarkably reduce organosulfates and secondary aerosol burden in the atmosphere. Updating the aromatic oxidation mechanism in models could result in more accurate treatment of particles formation for urban regions with considerable SO 2, NH 3, and aromatics emissions.
