  • Reduced Emissions for Landfill Gas Installations

    The use of landfill gas as a source of renewable energy is increasing. For environmental and safety reasons, the owners of the waste storage sites have to strictly monitor and control the construction, operations, and emissions generated. Sulzer offers solutions to control these emissions within the limits given by the government. Landfill gas is similar to natural gas, but it is created by ...

  • Mobile Stationary Source Emissions Testing, Coming to a Facility Near You?

    Last week, Antea Group had the unique opportunity to perform a RATA (relative accuracy test audit) of the emissions from a thermal oxidizer at an ethanol production facility located in Minnesota using a state-of-the-art mobile testing laboratory. During this RATA audit, actual stack emissions levels (including NOx, SOx, CO2, CO, O2, flow rate, temperature, velocity and pressure) from the ...

  • On the right track

    High-speed train manufacturer, CAF, rely on world-class beamforming technology to reduce the noise generated by their trains – helping to make high-speed trains a more viable option for travellers and operators alike. Because of its relatively low levels of CO2 emissions, train travel is considered one of the ...

  • Sensitivity of AERMOD in Modeling Fugitive Dust Emission Sources

    Dispersion modelers have long faced challenges estimating ambient pollutant concentrations caused by releases from “fugitive” sources of particulate matter, such as paved and unpaved roadways, raw material storage piles, outdoor material processing operations, agricultural activities, or windblown dust in general. Fugitive emissions are commonly defined as those that could not ...

  • Sources of particulate matter: emission profile of biomass burning

    Biomass burning is an important source of atmospheric Particulate Matter (PM) in Brazil: the burning of forests in the northwest and of sugar cane plantations in the southeast are important examples. The objective of this work is the measurement of the PM emission profile of burning of sugar cane and other characteristic vegetative burning in the region of Sao Carlos-SP/Brazil. Samples of PM10 ...

  • Sources of PCDDs/PCDFs In Cement Kiln Emissions

    Abstract This paper presents data on the source of PCDDs/PCDFs in cement plant stack emissions, demonstrating that these emissions are not necessarily all created by the process. The data potentially demonstrates that some of the PCDDs/PCDFs in the emissions are pre-existing dioxins and furans that are vaporized out of the kiln raw feed. This calls into question the assumption that PCDD/PCDF ...


  • Acoustic emission source localisation on bone using multiple regression

    A regression source location algorithm is developed to locate microcracks in bovine bone samples. Bone samples measuring 60 mm long, 22 mm wide and 5.5 mm thick were harvested from bovine femora. Artificial acoustic emission sources were created on the bone samples. The known location of these acoustic emission sources and the recorded arrival times at four acoustic emission sensors were used to ...

  • Retrofitting diesel engines: reducing the emissions of our ideal power source

    Over the past several years, Avogadro Environmental has been working with a number of clients to develop proactive environmental programs as part of their EPA Performance Track and ISO 14001 management systems.  Many client companies that are proactively implementing measures to reduce their environmental footprint are looking for ideas.  Diesel engine retrofits for off-road stationary and mobile ...

  • Effect of carbon sources on nitrous oxide emission in a modified Ludzak Ettinger process

    Effect of methanol and glycerol on nitrous oxide (N2O) emission in two laboratory-scale modified Ludzak Ettinger (MLE) processes was investigated during three distinct periods: dissolved oxygen (DO) control by intermittent aeration with a DO controller, and high and low aeration rates. N2O consumption rate in an anoxic tank and aeration mode influenced N2O emission rates from ...

  • Another source of methane release

    Mary Kang wasn’t even originally looking at methane emissions. The Princeton doctoral candidate was trying to get to the bottom of another issue: carbon dioxide escaping after being stored underground. During that research, she got to wondering about methane emissions from old oil and natural gas wells. What Kang, now a Stanford postdoctoral researcher, and other researchers found could be ...

  • Performance specification YY: Specifications and test procedures for Xray fluorescence based multi-metals continuous emission monitoring systems at stationary sources case study

    Performance Specification YY details the performance requirements for a multi-metals continuous emissions monitor that utilizes x-ray fluorescence (XRF) as an analytical technique. Each XRF based multi-metals CEMS must meet the criteria for accuracy, stability, and instrumental response laid out in this document. In addition, every XRF multimetals CEMS must meet the installation requirements in ...

  • Method X: Determination of metal concentrations in emissions from stationary sources (instrumental analyzer procedure) case study

    Method X is an instrumental analyzer procedure for the determination of multiple metals using x-ray fluorescence as an analytical technique. Method X specifies the criteria for accuracy stability and precision that must be met by an x-ray fluorescence based instrument analyzer. Method X also describes the emission test procedures associated with an x-ray fluorescence based metals measurement ...

  • A Case Study in Implementation of the National Emission Standard for Hazardous Air Pollutants for the Portland Cement Industry at a Major Source

    The regulations at 40 CFR 63, Subpart LLL are commonly known as PC MACT because the rule establishes the maximum available control technology for hazardous air pollutants (HAPs) from portland cement plants in the United States. There are 188 HAPs specified in Section 112 of the Clean Air Act Amendments of 1990. Two classifications of HAP emitters are specified in 40 CFR 63. Major sources of HAPs ...

  • Car emissions: taking tests out of the lab and onto the road

    Every year 430,000 Europeans die prematurely due to air pollution. One of the main sources is road vehicles emitting nitrogen oxides (NOx), including poisonous nitrogen dioxide. Following the Volkswagen scandal, in which the company admitted cheating emission test in the US, Parliament and the Council are considering to update existing emission rules to ensure tests are closer to real driving ...

  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...
