  • Technology: clean air’s unsung hero

    Last year, we celebrated the 40th anniversary of the U.S. Clean Air Act (CAA) and the 20th anniversary of the 1990 Amendments to the CAA. The CAA has been a huge success. From 1990 to 2008, emissions of six common pollutants were down 41%, while gross domestic product grew 64%. Emissions of volatile organic compounds dropped 31%, carbon monoxide dropped 46%, and sulfur dioxide dropped 51%. Lead ...

  • The Right Mix for Clean Air

    Reducing air pollution is an increasingly important topic all around the world. Many governments—also in developing countries—set new limits for emissions such as nitrogen oxides in flue gas. Sulzer offers advanced mixing technology for flue gas cleaning. The installation in a large power plant shows that these high-performance mixers can cope with the most difficult requirements. ...

  • New fertilizer industry gas cleaning technology achieves lower required emission levels

    All fertilizer plants produce dust and gases, such as ammonia (NH3) and acid fumes, which must be removed at very high efficiencies before venting to atmosphere. Familiar examples are granulation and prilling of nitrogenous products such as Urea which is the most widely used fertilizer in the world(1). Phosphatic fertilizer production produces dust and Fluorine compounds. Typical air treatment ...

  • Big Clear Sky – A short history of the Clean Air Act

    Major advances over 50 years have led to cleaner air and groundbreaking technology. The detrimental impact of industrialization to air quality in the United States went unchecked through federal legislation for most of the first half of the 20th Century. But following the 1948 industrial catastrophe in Donora, Pennsylvania – where a cloud of smog killed 20 and injured thousands – regulation of ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...
