  • 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, ...

  • A Comparison of Three Wastewater Collection System VOC Emissions Models

    Three models were compared to determine their ability to accurately predict emissions from two wastewater collection system components; gravity flow reaches and drop structures. Models investigated included the INTERCEPTOR Model, TOXCHEM+ and WATER9.Data used to perform the analysis were obtained from published literature. A total of 128 individual runs per model were completed in performing the ...

  • Testing VOC Evaporation Losses from Floating Roof Tank Turnovers

    Air emissions from floating roof tanks have been well characterized and documented by the U.S. Environmental Protection Agency (EPA). The estimation methods have been revised and updated throughout the years. However, an unusual aspect of air emissions from tanks with a floating roof during a tank turnover has not been addressed. Petroleum storage tank floating roofs are landed on tank legs and ...

  • Case study - Styrene emissions: Catalytic oxidizer with concentrator

    Overview The world's largest button manufacturer needed a pollution control system that would destroy styrene emissions from a variety of plant processes. The plant was ...

  • VOC composition and ozone-forming potential of the exhaust gas of in-use motorcycles

    The emission profile of volatile organic compounds (VOC) and the ozone-forming potential (OP) of the exhaust gas of six in-use motorcycles (four 4-stroke- and two 2-stroke-engines) were determined. The motorcycles were tested on a chassis dynamometer in a real-world driving cycle. The analysis involved the C2–C12-hydrocarbons as well as the aldehydes and ketones. Additionally, the regulated THC ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Short distance modification of vehicular exhaust VOC fingerprint

    This work aims to investigate how volatile organic compounds (VOCs) emitted from vehicular exhausts behave in regard to their role in pollutant photochemical reactions at very short distances from their source. Results obtained with a receptor model of ambient VOC data measured at two sampling sites in the city of Rome, placed at different distances from the traffic line, have been compared with ...

  • Case study - Printed circuit board emissions

    Overview One of the world's largest printed circuit board (PCB) manufacturers was required to install air pollution abatement equipment to control the VOCs emitted during their soldering ...

  • Infrared differential absorption Lidar (DIAL) measurements of hydrocarbon emissions

    We report the application of an infrared (IR) differential absorption Lidar (DIAL) system (also capable of ultra violet measurements) built at the National Physical Laboratory (NPL), UK, to field measurements of total site emissions (controlled and fugitive) from petrochemical and landfill installations. The validation of the IR-DIAL was carried out via a series of controlled field experiments ...

  • Expert insight: test method basics for oxidizer permit requirements

    Whenever a new oxidizer is installed to control Volatile Organic Compound (VOC) emissions, the question often comes up: What test method should I use to demonstrate that the device meets permit requirements?   Most states allow you the choice of three EPA Test Methods: 18, 25 and 25A. Of these, use of Method 25A is usually the most desirable, for a few reasons. One, Method 25A provides real ...

  • Compost biofiltration: an effective biological treatment system for treating volatile organic compounds from waste gas emissions

    Biofiltration, a simple technique involving microorganisms supported on a solid matrix, offers an attractive solution for the removal of volatile organic compounds (VOCs). The removal of benzene, toluene and xylene (model VOCs) in vapour phase has been compared individually in the present study using three biofilters. These biofilters were operated at different flow rates and concentrations ...
