  • Controlling Fugitive Emissions, Part 1: Close Capture Hooding

    Fugitive emissions, in their simplest form, are the uncontrolled release of gases to the atmosphere. Each one of us may contribute fugitive emissions when we fill our automobile gas tanks. The displacement of air inside the gas tank causes gasoline vapor emissions (hydrocarbons) to exit out the fill spout (un-controlled) to ...

  • Controlling Fugitive Emissions, Part 2: Permanent Total Enclosure

    Fugitive emissions are the uncontrolled release of gases into the atmosphere. This is something that occurs regularly; in fact, it often happens when we fill our cars' gas tanks. The air being displaced inside the gas tank when it is being filled causes gasoline vapor emissions (hydrocarbons) to exit into the atmosphere in an ...

  • 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 ...

  • Soil Vapor Extraction (Ex Situ)

    Introduction: Ex situ soil vapor extraction (SVE) is a full-scale technology in which soil is excavated and placed over a network of aboveground piping to which a vacuum is applied to encourage volatilization of organics. Soil piles are generally covered with a geomembrane to prevent volatile emissions and to prevent the soil from becoming saturated by precipitation. The process includes a ...

  • Thermally Enhanced Soil Vapor Extraction

    Introduction Thermally enhanced SVE is a full-scale technology that uses electrical resistance/electromagnetic/fiber optic/radio frequency heating or hot-air/steam injection to increase the volatilization rate of semi-volatiles and facilitate extraction. Thermally enhanced SVE is normally a short- to medium-term technology. Electrical Resistance Heating Electrical resistance heating uses ...

  • New University of Minnesota study documents mercury vapor emission levels and need for safer packaging, storage and transportation of fluorescent lamps

    Results of a recent study conducted by the University of Minnesota School of Public Health, Division of Environmental Health Sciences suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against mercury vapors emitted from broken lamps. The new study, published in the March issue of the ...

  • Double Duty Scrubber for TDI Fumes A case-history description of a relatively uncomplicated but effective method for handling large runaway emissions of TDI and solvent vapors.

    NKI (B. V. Nederlandse Kleurstofindustrie, a subsidiary of Morton-Thiokol, Inc. U.S .A.), and one of the major industrial firms in the Netherlands, had a problem with extremely toxic TDI (toluene di-isocyanate) emissions from one of their processes . On a batch basis in different reactors, the largest being 6.5 m cubed(1717 U.S . gallons), a solution polymerization of TDI with polyols in a ...

  • Effective control of fugitive emissions

    Are you Building a brand new process and want to get through the permit process quickly? Looking for ways to further reduce emissions? Under an order from U.S. Environmental Protection Agency (EPA) to further reduce emissions? With EPA continually pressuring industry to reduce emissions, control of fugitives is increasingly important to your overall emissions ...

  • Metal Coating Emission Control

    The use of regenerative thermal oxidizers is expanding into applications where they wouldn’t have been considered years ago, says Mike Scholz 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 ...

  • Overview of Major Changes in EPA Draft Guidance for Vapor Intrusion

    The following provides a brief summary of the Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway From Groundwater and Soils (Subsurface Vapor Intrusion Guidance). November 2002, EPA530-F-02-052. Major Points: This draft guidance supersedes the draft RCRA EI Supplemental Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway (Dec. 2001). It does not supersede ...

  • Air Emissions/Off-Gas Treatment

    A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

  • A cure for Environmental Emissions case study

    Disposing of nearly 1 million pounds of medical waste a month is no easy task. The wet electrostatic precipitator, installed at Rochester, MN-based Mayo Clinic, seems to be just what the doctor ordered. While the medical waste incinerator at Mayo Clinic in Rochester, MN, consistently met state and federal emission requirements, facility leadership recognized that installing a wet electrostatic ...

  • Hydrocarbon evaporative emissions & control for automotives

    Even the cleanest and most efficient vehicle on the market today still pollutes the air and otherwise damages the environment. Motor vehicles emit several noxious pollutants which vehicle emissions standards are designed to regulate. Vehicles generally emit Hydrocarbons (HC), Carbon monoxide (CO), Nitrogen oxides (NOx) and Fine airborne particulate matter (PM) as pollutants that require control. ...

  • Put energy into emission control projects

    Many companies feel pressured to spend the least amount possible to meet environmental regulations, primarily because compliance isn’t a profit generating endeavor. What some environmental and compliance managers fail to realize is that emission control equipment can quickly become a profit decreasing endeavor with this penny wise-pound foolish approach. With mandatory greenhouse gas (GHG) ...
