  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Case study : VOC analysis in ambient air by FID dectection - Complete system airmOzone

    Ozone concentration has been multiplied by 5 in the last century in the middle latitudes of the northern hemisphere from 10 PPB in 1874 to approximately 50 PPB today. This is an increase of 1.6% per year; the trend is probably higher (2.4% a year) over the last decades. (Chapter 1 of the International Geosphere-Biosphere Program - World Climate Research Program) In order to stop this global ...

  • ”Catalytic VOC oxidation has been an excellent VOC elimination method in our paint plant”, Pekka Kotilainen, Environmental Manager, Tikkurila Oyj, FIN

    Tikkurila has been succesfully treating VOC emissions in paint production with catalytic VOC incinerator for years For already 17 years, Tikkurila has been treating the VOC emissions in Finland’s paint production plant with the first regenerative catalytic VOC oxidizer on the market. Catalytic incineration has proven to be a very applicable, easy and effective way to respond to ...


  • Case study - RTO handles high VOC loading at silgan containers

    OVERVIEW Regeneration Game - Originally printed in The Canmaker Magazine - Sayers Publishing Group As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems. Like many others in the industry, a Silgan canmaking plant in the ...

  • Chromatotec monitor air quality in Arcachon Bay through its own air quality station

    Chromatotec® made this summer the inauguration of its private monitoring station in Andernos-les-Bains. With a wealth of experience, thanks to which it already deployed massively its systems around the world, the group wanted to implement its own monitoring station to have complementary information to the actual air quality network. These data will allow the group to extend its ...

  • Potential use of Syntrichia ruralis for monitoring atmospheric BTEX

    Many studies deal with the bioaccumulation of metals in mosses. In contrast, the knowledge about organic pollutants is less extensive and there is a relative lack of studies using plants for the biomonitoring of volatile organic compounds such as Benzene, Toluene, Ethylbenzene and Xylenes (BTEX). Both in situ and in controlled conditions, this study deals with the capacity of mosses to accumulate ...
