  • Critical Monitoring of Forklift Emissions and Warehouse Ambient Air Quality - Case Study

    Our team of experts has been hard at work and has just released an industry-leading report detailing Forklift Emissions in Warehouses: The main objectives of this study were to investigate the effects of different engine conditions on exhaust gas emissions and to observe the effect that forklift emissions have on the ambient air quality of the warehouse.             ...

  • How conditions affect cookies and air pollution control solutions

    Chocolate chip cookies are one of my favorite treats. Butter, sugar, eggs, flour, vanilla, and, of course, chocolate chips. Combine the ingredients together and you get a delicious cookie. Somehow, using the same ingredients the cookies do not always turn out the same. Sometimes they are thinner and crispier. Other times, they are soft and chewy. After watching cooking shows, I have come to ...

  • A quick guide to oil analysis for engine test applications

    Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

  • 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 ...

  • Real-time air emissions monitoring

    Due to increasingly rigorous requirements for regulatory and permit compliance, organizations are seeking more from all compliance support systems. The ability to expand systems to encompass new, or migrate existing, regulatory calculations used to monitor environmental performance is vital. Planning strategically for a scalable and sustainable system has been shown to reduce overall compliance ...

  • The Emissions Trifecta: Combining Title V, Air Emissions and GHG Reporting

    With greenhouse gas (GHG) and other pollutants meeting increased scrutiny worldwide, governmental agencies have put multiple regulations and environmental programs in place to tackle this growing problem. But effectively tracking and managing data for Title V, an air emissions inventory and the EPA’s new mandatory GHG reporting rule can prove to be overwhelming for companies, consuming ...

  • 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 ...

  • 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 ...

  • Recovering Valuable Chemicals from Air Emissions

    Air emissions in many cases are a waste of valuable natural resources that should have become useful chemicals. In some cases the economic payback from recycling/reuse of air emissions can be almost as much a motivation to control air pollution as government regulations. Examples of recycling and reuse of air emissions are sulfur oxides emissions that can be made into sulfuric acid, cement ...


  • 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 ...

  • 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 ...

  • A cost-effective method for controlling compost air emissions

    In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

  • 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 ...

  • Concentrations of air pollutants constant despite drop in emissions

    Concentrations of ozone and particulate matter, two harmful airborne pollutants, have not improved since 1997 despite substantial cuts in emissions of air pollutants across Europe, says a new EEA report where Norwegian Institute for Air Research (NILU) has co-ordinated and are editor ...

  • 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 ...

  • Clearing the air: the use of bio-oxidation for industrial air emissions control

    The wood products industry began rather ardous road to emissions control in the early 1990s with the first installation of a thermal oxidizer (an RTO) at a California MDF facility, for volatile organic compound (VOC) control. During the ensuing years, virtually every panel board facility has had to control emissions of VOCs, and up until the last few years, always with some sort of thermal ...


  • Kinetic Evaluation of H2S and Ammonia Biofiltration for Air Emissions Control

    ABSTRACTTraditionally the control of H2S emissions includes direct air stripping, precipitation and chemical oxidation. In this study, low cost biofiltration using a natural media of wood chips and compost and a commercial biofiltration media were evaluated for the removal of moderate concentrations of H2S (up to 50 ppmv) at different Empty Bed Contact Times (EBCT) in the range of 10-80 seconds. ...


  • Air Quality and Emissions Monitoring: What does best practice look like?

    When we turn on the tap, we know that the water coming out should be of a consistently high quality. And we can choose – if we prefer – to drink bottled water instead. This is not so with the air that we breathe. Unlike the water that we drink, we have no guarantee, and in many cases no information, telling us that the air quality in our towns, cities and even rural areas is of an ...
