  • New process removes sulfur components, carbon dioxide from power plant emissions

    The Department of Energy's Pacific Northwest National Laboratory has developed a reusable organic liquid that can pull harmful gases such as carbon dioxide or sulfur dioxide out of industrial emissions from power plants. The process could directly replace current methods and allow power plants to capture double the amount of harmful gases in a way that uses no water, less energy and saves money. ...

  • ASTM D1607 - 91(2011) standard test method for nitrogen dioxide content of the atmosphere (griess-saltzman reaction)

    Nitrogen dioxide plays an important role in photochemical smog-forming reactions and, in sufficient concentrations, is deleterious to health, agriculture, materials, and visibility. In combustion processes, significant amounts of nitric oxide (NO) may be produced by combination of atmospheric nitrogen and oxygen; at ambient temperatures NO can be converted to NO2 by oxygen and other atmospheric ...

  • Coastal Waters Most Sensitive to Acid Rain

    FALMOUTH, Massachusetts, September 11, 2007 (ENS) - The release of sulfur and nitrogen into the atmosphere by power plants and agriculture plays a small role in making the ocean more acidic on a global scale, but the impact is amplified in shallow coastal waters, finds new research by atmospheric and marine chemists. Ocean 'acidification' occurs when chemical compounds such as ...

  • Dupont and Lucite international agree to pay $2m for clean air violations

    DuPont and Lucite International Inc. have agreed to pay a $2 million civil penalty to settle Clean Air Act violations at a sulfuric acid plant in Belle, W. Va., the U.S. Environmental Protection Agency, the U.S. Justice Department, and the state of West Virginia announced today.    The sulfuric acid plant is located on a 100-acre chemical manufacturing complex along the Kanawha ...

  • Clean Coal Technology development in China

    The United States has invested over $ 100 billion research and development of modern clean coal technology, greatly reducing emissions of sulfur dioxide, nitrogen oxides and mercury and other major pollutants when fired. According to China's Ministry of Statistics, in 2012 4.1 million tons of soot emissions from coal-fired boilers, 5.7 million tons of sulfur ...


  • Geo-engineering and sea-level rise over the 21st century

    Scientific findings by international research group of scientists from England, China and Denmark just published suggest that sea level will likely be 30-70 centimetres higher by 2100 than at the start of the century even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and greenhouse gas emissions are stringently controlled. Most ...


  • Modelling marine exhaust emissions in the Baltic Sea

    A new tool used to investigate exhaust emissions of marine vessels has been developed and applied to shipping in the Baltic Sea. The Baltic Sea is a busy maritime region with 3500-5000 ships operating in the area every month. Emissions from shipping contribute significantly to atmospheric pollution, leading to health and environmental problems. In May 2006, the Baltic Sea was the first area ...
