  • Case study : VOC analysis in ambient air by FID dectection - Complete system airmOzone

    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. (Chapter 1 of the International Geosphere-Biosphere Program - World Climate Research Program) In order to stop this global ...

  • 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 and coating process. Three main considerations were important to the customer: The need for a system with a competitive capital cost and the lowest possible operating cost ...

  • 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 ...

  • Controlling Pharmaceutical Coating & Drying Process Emissions

    Capturing and destroying harmful emissions from pharmaceutical processes can be challenging. It’s not because the volatile organic compounds (VOCs) are difficult to destroy using catalytic or thermal techniques. It’s because their concentrations can be so high. These process streams raise safety concerns, both when they’re collected in vents and when they reach the final ...

  • 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 ...

  • 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 proactively seeking a cost-effective air pollution control solution to preempt future regulatory action. The main concern of the customer was the high operating cost of an emission control system. ...

  • 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 ...

  • Efficiency Bonus From Ford’s Emission-Beating Ovens

    EFFICIENCY BONUS FROM FORD’S EMISSION-BEATING OVENS When Ford decided it was time to refurbish and upgrade two primer ovens and systems at its Dagenham plant in Essex, UK, the company looked to the future. Against a worldwide background of rising concern over environmental issues and pollution, Ford decided to make use of the opportunity to reduce VOC emissions. They aimed for a system ...


  • Air Emissions from the automobile manufacturing industry: a bio-oxidation pilot study of paint emissions control

    Bio•Reaction Industries (BRI) was contacted by Toyota to assess the abatement potential of an engineered bio-oxidation system (biofilter). The proposed intent of the pilot was to evaluate the effectiveness of biofiltration as available alternative to traditional VOC removal technology on an existing 3 stage wheel paint booth. A pilot unit consisting of a biotrickling filter and a separate ...


  • Sensitivity of ozone and aerosols to precursor emissions in Europe

    We modelled the air quality in Europe during January and June 2006 using the MM5/CAMx model system and studied the sensitivity of ozone and aerosol formation to precursor emissions. Increased isoprene emissions by a factor of four in summer caused an increase in afternoon ozone by up to 10%. On the other hand, the effect on secondary organic aerosols (SOA) was very small. Reductions in ...

  • Studying the influence of biogenic emissions on AOT40 levels in Europe

    It is well known that the uncertainties in determination of biogenic emissions are very large (some authors claim that these emissions are underestimated in certain areas of the world by up to ten times). On the other hand, anthropogenic emissions in some areas of the world have been reduced very considerably during the last two decades (this is especially true for Europe). This fact shows ...

  • Case study - Flexographic printer: efficient emissions

    Problem Control of air emissions has become an important issue that flexible packaging converters must consider when changing or upgrading equipment. Robbie Manufacturing of Lenexa, KS, a producer of printed shrink films, bags and pouches for a diverse range of applications, addressed its emissions in 1991 and 1996 by investing in two catalytic oxidizers to control the EPA-regulated air ...

  • 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 ...

  • Performance of a Compost-Based Hybrid Bioreactor for the Treatment of Paint Spray Booth Emissions

    ABSTRACT Recently, application of vapor-phase bioreactors to the treatment of volatile organic compounds  (VOCs) from paint spray booths has drawn increased interest.  Contaminated air streams from paint spray booths are characterized by transient loading conditions and chemical mixtures consisting of both hydrophobic (e.g., xylene and toluene) and hydrophilic compounds (e.g., ketones).  The ...


  • Meeting emission control through improved actuation

    Introduction Reducing fugitive emissions, particularly methane, is a major priority in the fight against climate change. Although valves and actuators have been the focus for reduction efforts because valve leakage accounts for more than half of total fugitive emissions, the problem is mainly old valves that weren't designed using the latest materials and technologies. New technologies can ...
