  • 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 ...

  • 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 ...

  • Minimizing Operating Costs in VOC Abatement Equipment

    Untitled Document As governmental regulations of environmental emissions become more restrictive, the average concentration of Volatile Organic Compounds (VOC's) has decreased as more ...

  • 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 ...

  • 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 ...

  • Odour control with Direct Cold Plasma

    Odour emission during the production or processing of food and feed is often an unwelcome side effect. However, by using cold plasma technology, the smell can be reduced up to 95%. Increasingly, feed manufacturers are being required to address the issue of emitting of odour and harmful contaminants into the surrounding community. Local communities, special interest groups and government ...

  • 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 ...

  • Cryogenic Treatment Unit (TU-51) for Recovery of VOCs for Soil Remediation

    A Cryogenic Treatment Unit or TU-51 was developed to apply a cryogenic air treatment process to recover persistent vapor phase volatile organic compounds (VPVOC) having extremely low boiling points. These would include explosive compounds present in the vapor stream. The portable TU-51VPVOC (OEM) operates the following process: vapors are recovered from geologic units via SVE, often from a ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...

  • Distribution of volatile organic compounds (VOCs) in surface water, soil, and groundwater within a chemical industry park in Eastern China

    This paper focuses on the distribution of volatile organic compounds (VOCs) in the surface water, soil, and groundwater within a chemical industry park in Eastern China. At least one VOC was detected in each of the 20 sampling sites, and the maximum number of VOCs detected in the surface water, groundwater, and soil were 13, 16, and 14, respectively. Two of the 10 VOCs with elevated ...

  • Reflections on new directions for risk assessment of environmental chemical mixtures

    Currently risk assessment of chemicals tackles them as single substances affecting individual health endpoints. In reality, human exposure occurs to mixtures of chemicals, as they are present in the environment and consumer products. Combining the information from environmental fate analysis, epidemiological data and toxicokinetic/dynamic models helps estimate internal exposure. Coupling these ...

  • Direct-Push Injection and Circulation Biobarrier to Remediate a TCE Groundwater Plume

    ABSTRACT: The goal of this study was to determine if direct-push drilling methods combined with a circulation system could be used to establish a passive biobarrier in a very transmissive aquifer to treat tricholoroethene (TCE). The Site is located in central Indiana, where historic use of TCE has impacted an unconfined aquifer. A plume consisting primarily of TCE has migrated from west to east ...

    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.
