Wastewater treatment plant monitors Greenhouse Gas emissions

by Gasmet Technologies Oy  (Apr. 16, 2014)

Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse ...

NOx Emissions trading scheme repealed in the Netherlands — Global Impacts?

by ENHESA - Global EHS & Product Compliance Assurance  (Feb. 5, 2013)

The once-trailblazing Dutch Nitrogen Oxides Emission Trading Scheme (NOx ETS) is to be repealed: what are the effects? In recent years, Emissions Trading Schemes have gained momentum around the world.  Hundreds upon thousands of companies have had to adapt to be able to handle the effects of more stringent regulation. The Netherlands ...

Comparison and evaluation of the 1 km and 5 km resolution FRAME modelled annual concentrations of nitrogen oxides

by Inderscience Publishers  (Dec. 28, 2012)

The aim of this paper is to compare and evaluate the modelled annual nitrogen oxides (NOx) air concentrations calculated for the same area at two different grid resolutions of 1 km and 5 km. The FRAME model was used for the domains covering Poland. Simulations were performed for the years 2005–2008. The input files for the model were provided ...

Nitrous oxide (N2O) emissions from biotrickling filters used for ammonia removal at livestock facilities

by IWA Publishing  (Mar. 13, 2014)

Recently several manufacturers of nitrifying biotrickling filters for ammonia (NH3) removal at animal houses have started to add a denitrification step to the installation, aiming to reduce the amount of discharge water by conversion of NH3 to nitrogen gas (N2). The aim of this research was to quantify the possible formation of nitrous oxide ...

Projecting emission reductions from prospective mobile sources policies by road link–based modelling

by Inderscience Publishers  (Jan. 23, 2014)

A methodology was developed to project total vehicular emissions from different emission reduction policies for the light–duty vehicles in the roads network of Tehran, Iran. A road–link–based model was constructed based on a bottom–up approach by coupling COPERT emission functions with the travel demand model of EMME/2. Results showed total ...

A selective catalytic system for greenhouse gas (NOx) emission reduction at a 2–ethyl hexanol plant

by Inderscience Publishers  (Jul. 26, 2012)

Trends of ambient NOX levels in the Jubail Industrial City, Saudi Arabia, are increasing, and the regulators have identified areas requiring substantial reductions to control the atmospheric NOX concentrations. In this study, a Selective Catalytic Reduction (SCR) system for the control of NOX ...

Exergy analysis of combustion characteristics and NOx emissions of a dual–fuel engine

by Inderscience Publishers  (Jun. 26, 2012)

The combustion characteristics and NOx emissions of compression ignition engines working on a dual fuel mode are investigated numerically and their exergetic efficiencies are determined. The model has been validated with available experimental results. The simulation results show that dual fuel engine combustion and trend of NOx ...

Diesel emission reductions through electrification of new England produce center TRUs case study

by M.J. Bradley & Associates LLC  (Oct. 31, 2013)

MJB&A acted as project manager to a New England Produce Center (NEPC) Transportation Refrigeration Unit (TRU) Electrification Project led by the Chelsea Collaborative, a community-based organization. NEPC, located in Chelsea, MA, is the second largest produce market in the U.S., and is the hub for virtually all produce deliveries in and out of ...

Sensitivity of ozone and aerosols to precursor emissions in Europe

by Inderscience Publishers  (Dec. 28, 2012)

We modelled the air quality in Europe during January and June 2006 using the MM5/CAMx model system and studied the sensitivity of ozone and aerosol formation to precursor emissions. Increased isoprene emissions by a factor of four in summer caused an increase in afternoon ozone by up to 10%. On the other hand, the effect on secondary organic ...

EU emission inventory report 1990-2011 under the UNECE Convention on LRTAP

by European Environment Agency (EEA)  (Jun. 26, 2013)

This document is the annual European Union (EU) emission inventory report under the United Nations Economic Commission for Europe (UNECE) Convention on Long-range Transboundary Air Pollution (LRTAP) (UNECE, 1979). The report and its accompanying data are provided as an official submission to the Executive Secretary of UNECE by the European ...
