  • Hourly NOx concentrations and wind direction in the vicinity of a street intersection

    This study relates NOxconcentrations and wind (speed and direction) measured inside an asymmetric street canyon, with ambient wind. The monitoring site is located near a street intersection. The wind measured at the domestic airport located in the city, near the coast, has been considered as ambient wind. Wind direction at the monitoring site inside the canyon is mainly from the E, NE, W and NW ...

  • NOx in Non-Utility Industries - Part I NOx in Non-Utility Industries - Part I - Air emission origins, best control solutions and monitoring methodology for nitrogen oxides

     Problems with reducing nitrogen oxides (NOx) are widespread in the general process industries. These industries, together with medium size utility and power generators contribute about 15 percent of global NOx emissions. The emission sources addressed include various heaters employed in chemical and petrochemical plants, nitric and sulfuric acid plants, glass furnaces, iron and steel mills, ...


  • Pharmaceutical Manufacturer Turns NOx Regulations Into an Opportunity – With a 6-Figure Annual Chemical Savings as a Bonus.

    This project was for a major manufacturer of a tabletted OTC analgesic. The manufacturing process was being redesigned, and a critical aspect of the work was the re-engineering of a reactor in the initial stage of manufacturing. The client’s original process, which used nitric acid to dissolve a metal, exhausted virtually 100% nitrogen oxide (NO), a toxic, wholly non-water-soluble gas that reacts ...

  • Evaluation of progress under the EU National Emission Ceilings Directive

    In 2001, the European Community adopted the National Emission Ceilings Directive (NEC Directive). Its objective is to limit the emissions of four important air pollutants in order to achieve the directive's interim environmental objectives concerning acidification and eutrophication in sensitive ecosystems, and health- and vegetation.related exposure to ground-level ozone. Over the past decade, ...

  • Effect of fuel additives on performance and exhaust emissions of direct injection diesel engine operating on B20 waste fish oil

    The ever increasing diesel consumption, rapid depletion of fossil fuels and environmental concern has prompted an intensive use of biodiesel produced from various sources. In this study, biodiesel (ethyl ester of fish oil) was prepared from fish oil and different blends of biodiesel–diesel (B20, B40, B60, B80 and B100) were examined in a single cylinder, constant speed, and direct injection ...

  • Performance and exhaust emissions of a two-stroke spark-ignition engine with a direct-injection system

    A direct fuel-injection system has been adapted to a small two-stroke spark-ignition engine to prevent the charge from flowing through the cylinder during the scavenging process. The injection system consists of a jerk-type pump and a single-hole nozzle which supplies gasoline to the cylinder. Engine tests were carried out for comparison with the carburettor version of the same engine. The ...

  • Costs and health benefits of reducing emissions from power stations in Europe

    Current levels of emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) from power plants generate very significant health and environmental damage across Europe. This study demonstrates that by applying up-to-date emission control technologies, these emissions could come down drastically. By estimating the costs and health benefits of further emission reductions, this study highlights the ...

  • The comparative analysis of diesel engine combustion and emission parameters fuelled with palm oil methyl esters and its diesel blends

    In this work, the combustion and emission characteristics of a direct injection compression ignition engine fuelled with diesel-Palm Oil Methyl Ester (POME) blends are investigated. This study shows that the ignition delay decreases with increase in the POME addition. The maximum rate of pressure rise and maximum rate of heat release decreases with increase in POME addition at all loads. As the ...

  • Air pollution by ozone across Europe during summer 2011

    Ozone is the main product of complex photochemical processes in the lower atmosphere, involving NOX and VOCs as precursors. Ozone is a strong photochemical oxidant. In elevated concentrations it causes serious health problems and damage to materials and vegetation such as agricultural crops. The main sectors that emit ozone precursors are road transport, power and heat generation plants, ...

  • BLUE LIGHT CONVERTER SIGNALS WAY FORWARD FOR NO2 MEASUREMENT

    Local authorities seeking more accurate NO2 readings should consider using analysers which incorporate ‘Blue Light Converters’ says air quality monitoring specialists Enviro Technology.   This comment comes following a presentation held at the Royal Society of Chemistry / AAMG Conference in December 2010 by EMPA (Switzerland) – an independent research and services ...

  • Reducing air pollution from electricity-generating large combustion plants in the European Union

    Background In 2008, the European Environment Agency (EEA) published a first assessment of the theoretical potential to reduce emissions of nitrogen oxides (NOX) and sulphur dioxide (SO2) from electricitygenerating large combustion plants (LCPs) (EEA, 2008). That earlier study showed that improving the environmental performance of existing LCPs by applying best available techniques ...
