  • 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 ...

  • Marine Monitoring of Emissions of Air Pollutants

    Many of us who are not in the marine shipping business probably think of vessels as practical means of transportation, or, when it comes to cruising ships,  a place to spend your vacation. However, not all of us realize that large ships also are floating large power plants, with all aspects that come with power plants including potential contribution to air pollution. The ...

  • Data Requirements Air Emissions/Off-Gases

    Predictive modeling may be usefelected to represent the system (e.g., SVE treatment, incinerator, etc.), and site and contaminant informaul in estimating emissions from a site or treatment system. An appropriate theoretical model is stion is used to estimate gross emissions. Because many variables affect emission rates, this approach is limited by the representativeness of the model and by the ...

  • Air emissions benchmarking report case study

    In 2008, 2010, 2012, and 2013, MJB&A managed the production, budget and release of a collaborative report entitled Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States.  The 2013 report was jointly published by Bank of America, Ceres, Entergy, Exelon, the Natural Resources Defense Council, Pacific Gas and Electric Company, Public Service ...

  • Controlling Hazardous Air Emissions With A Catalytic Oxidizer

    As the full effect of the Federal Clean Air Act (CAA) Amendments continue to impact today’s industry, many companies will be required to install new or additional air pollution control equipment. With well over twenty years of proven success, catalytic oxidation is a popular method for controlling volatile organic compound (VOC) emissions.During the past 25 years, industry has made progress in ...

  • Can Composting BMPS Reduce Air Emissions?

    Imagine a scenario where all yard trimmings collected for recycling have to be received, processed and composted under the cover of a building. It would be tough for most yard trimmings composting facilities to survive the expense. Yet this situation could have occurred in Southern California. At one point, the South Coast ...

  • Air emissions impact measurements at a perchloroethene remediation site

    As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order ...

  • National Air Pollutant Emission Trends, 1900-1998

     Executive Summary What information is presented in this report? This report presents the United States (U.S.) Environmental Protection Agency’s (EPA) latest estimates of national emissions for criteria air pollutants: carbon monoxide (CO), nitrogen oxides (NOX ), volatile organic compounds (VOC), sulfur dioxide (SO2 ), particulate matter (PM) less than 10 ...

  • Air–quality impact of PM10 emission in urban centres

    This paper calculates a detailed inventory of PM10 emissions in the urban area of Mendoza, Argentina, and evaluates the impact of such emissions by using the CALPUFF dispersion program. It includes direct and indirect emissions from mobile sources; emissions from industrial sources and fugitive emissions from unpaved road and dust production from bare land. The main results show the relevance of ...

  • 3-in-1 Flame-Ox High BTU Thermal Oxidizer - Case Study

    Environmental Issues Controlling the off-gas from a remediation project, where high concentrations of petroleum hydrocarbons are present, can be a difficult if not dangerous process when utilizing internal combustion engines and conventional oxidation technology. In more recent years, the use of high vacuum pumps to accomplish both liquid and gas phase extraction — sometimes ...

  • The US Clean Air Act: Improving air quality and tracking greenhouse gas emissions?

    The US Clean Air Act is a federal law designed to reduce air pollution in order to improve the nation’s overall air quality. The intent of the federal law is to identify and reduce harmful substances that weaken the stratospheric ozone layer and continue to contribute to global climate change.Many of these pollutants, refrigerant gases, or Greenhouse Gases (GHGs) can be found within companies, ...

  • Criteria and Air-Toxic Emissions from In-Use Automobiles in the National Low-Emission Vehicle Program

    The U.S. Environmental Protection Agency (EPA) implemented a program to identify tailpipe emissions of criteria and air-toxic contaminants from in-use, lightduty low-emission vehicles (LEVs). EPA recruited 25 LEVs in 2002 and measured emissions on a chassis dynamometer using the cold-start urban dynamometer driving schedule of the Federal Test Procedure. The emissions measured included regulated ...

  • EMEP/EEA air pollutant emission inventory guidebook 2016

  • The Whole Plant Approach to Air Emission Modeling for NESHAP Compliance

    ABSTRACTLong overlooked, the air emissions associated with biological treatment of process wastewaters continue to be further scrutinized and regulated. The common approach is to utilize EPA’s Water9 as a model to present findings and support permitting activities. It is essential when using a model that not only is the facility modeled appropriately, but also that the specific compound ...
