  • Control VOCs and Odors

    Manufactured gas plants (MGPs) have kept cities Iighted and fueled since the Industrial Revolution. Today, cleaning up these sites presents a special challenge because of the potential for release ofVOCs and odors. Fortunately, remediation professionals have several effective emission control technologies to choose from. Where are they located? The historical record of MGPs in the United States ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • 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 ...

  • 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 ...


  • 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 ...

  • 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 ...

  • 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 ...


  • Biofiltration of hydrophobic VOCs pretreated with UV photolysis and photocatalysis

    The effects of pretreatments on the biofiltration of gas phase α-pinene, a poorly water soluble Volatile Organic Compound (VOC), was evaluated in a controlled and long-term experimental investigation. Ultraviolet (UV) photolysis and photocatalysis were used and compared as pretreatment techniques. A control experiment involving biofiltration alone allowed for the direct evaluation of the coupled ...
