  • Gas Chromatography: MCERTS Certification for Ambient Air Analysis on Benzene and VOCs

    Due to environmental issues, the world of gas analysis is evolving very rapidly. Governments set the rules to limit and control the environmental pollution through legislation. Volatile organic compounds (VOCs), often produced by human activities, are amongst the sources of pollution that need to be identified and quantified for safety reasons. Exposure to high concentrations of certain VOCs is ...

  • Chemical loss of volatile organic compounds and its impact on the source analysis through a two-year continuous measurement

    Chemical loss of volatile organic compounds (VOCs) is more important than the observed VOCs, which is the real actor of the chemical process in the atmosphere. The chemical loss of VOCs might impact on the identification of VOCs sources in ambient. For this reason, VOCs with 56 species were continuously measured in the urban area of Shanghai from 2009 to 2010, and based on the measurement the ...

  • Potential of biofiltration for VOCs emission control and safety aspects

    Directive 99/13/EC on the emission of Volatile Organic Compounds (VOCs) is impacting on several industries in Italy, as well in other EU countries. Many small enterprises have to invest in new control systems and need to be helped to choose an appropriate and safe technology. As VOCs are highly flammable compounds, high concentrations in emission flows can pose a fire and explosion hazard if ...

  • VOC Oxidizers: Where to begin?

    If you are wanting to solve a VOC (volatile organic compound) air pollution problem, how do you begin?  What type of solution is best suited for the application?  What are the various types of thermal oxidizers and how do they differ in design? RTO, Recuperative TO, Direct fired TO, carbon systems, or concentrators -- which should be used for an application in a chemical plant, refinery, an ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...

  • Properties and Behavior of Halogenated VOCs

    An important consideration when evaluating a remedy is whether the compound is halogenated or nonhalogenated. A halogenated compound is one onto which a halogen (e.g., fluorine, chlorine, bromine, or iodine) has been attached. The nature of the halogen bond and the halogen itself can significantly affect performance of a technology or require more extensive treatment than for nonhalogenated ...

  • Installation of EHC for VOCs

    Project Installation of EHCT for Treatment of Chlorinated Volatile Organic Compounds Summary Adventus installed 1 ton of EHC® into a trench and 3 tons of EHC® into an open excavation at a site that has groundwater contaminated with a mixture of chlorinated solvents. The Challenge Two areas of contamination were targeted for ...


  • VOC`s oxidation

    Real Decreto 117/2003, dated 31st January related to Volatile Organic Compounds emission limits, due to organic solvents, as well as Law 16/2002, dated 1st July, related to prevention and integrated control of pollution (IPPC), came into force, which will impel many industries to set devices for the treatment and elimination of gases effluents with different organic compounds content. Here, we ...

  • Flavoring & Fragrance Manufacturing Solutions for VOC and Odor Control - Case Study

    Volatile Organic Compounds (VOCs) and odors are natural by-products of many chemical manufacturing processes. The manufacturing of powdered and liquid flavorings & fragrances involves production phases where VOCs and odors can escape into the ambient air. Recapture of the VOCs is important in the prevention of air pollution and smog. Smog is formed when VOCs react with nitrogen oxides (NOx) ...

  • 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 ...

  • Intellisenc Building Air Quality Controllers control CO2, CO, VOC, O3, Humidity and temerpature.

    The quality of the air we breathe indoor (Indoor Air Quality, IAQ) is typically defined by the air chemical or gas composition and particulates. The sensors available today for sensing the gas composition of IAQ have many features and options. There is a wide application base for IAQ sensing with the most common being the regulation of HVAC ventilation systems for lower energy cost. Using an IAQ ...


  • Biofilter Removal of VOCs and Toxics from Airborne Emissions

    Abstract Sewage treatment plants can emit significant quantities of volatile organic compounds (VOCs) and toxic air contaminants, but emission control by conventional methods has been difficult to achieve. The biofilter technology developed in a previous contract can satisfactorily control emissions from these plants and possibly from other sources of high-volume, low-concentration emissions ...
