  • Intelligent Pollution Control

    The world faces difficult pollution control decisions. For every dollar spent on pollution control, there is an alternative investment in health improvement. For every dollar spent on reducing one pollutant, there is an alternative to reduce another. The most prudent course to make the best investment should include: Intelligent uncertainty Intelligent classification of options ...

  • A cost–effective backward Lagrangian method for simulation of pollutant formation in gas turbine combustors by post–processing of complex 3D calculations

    A backward Lagrangian Monte Carlo modelling is proposed to calculate by post–processing the PDF of the thermo–chemical parameters of complex turbulent reactive flows simulated with a simple turbulent combustion model. PDF's of minor species such as pollutant species (NOx, soot, unburnt hydrocarbons...) can be easily obtained as long as these species have no significant influence on the main ...

  • NOx in Non-Utility Industries - Part I NOx in Non-Utility Industries - Part I - Air emission origins, best control solutions and monitoring methodology for nitrogen oxides

     Problems with reducing nitrogen oxides (NOx) are widespread in the general process industries. These industries, together with medium size utility and power generators contribute about 15 percent of global NOx emissions. The emission sources addressed include various heaters employed in chemical and petrochemical plants, nitric and sulfuric acid plants, glass furnaces, iron and steel mills, ...


  • Annual European Union greenhouse gas inventory 1990–2014 and inventory report 2016

    ES.1 Background information on greenhouse gas inventories and climate change The European Union (EU), as a party to the United Nations Framework Convention on Climate Change (UNFCCC), reports annually on greenhouse gas (GHG) inventories for the years between 1990 and the current calendar year (t) minus two (t–2), for emissions and removals within the area covered by its Member ...

  • NOx re-burn simulation in a double-jet counter-flow flame

    The paper investigates the main features of NOx emission in a laminar double-jet counter-flow diffusion flame for later use as a possible physical model for NOx reduction through turbine in situ reheat. The oxidizer stream consists of exhaust gas resulted from a conventional combustor and the fuel stream is represented by an air?methane mixture. The main interest rests on the distribution of NOx ...

  • Permit Compliance Monitoring for the Power Generation Industry

    The Clean Air Act Amendments (CAAA) of 1990 authorized EPA to develop regulations requiring facilities to monitor the adequacy of emission control equipment and plant operations. This paper discusses the various methods available for coal-fired power plants and gas turbine installations to demonstrate a reasonable assurance of facility compliance with emission limitations, and ensure that control ...

  • Los Angeles County Sanitation Districts: Siloxane Removal

    Los Angeles County Sanitation Districts have long been involved with recovering landfill and digester gas for energy to power turbines and internal combustion engines. Their experience led them to identify performance issues associated with these gases. One particular challenge is siloxanes. Cyclic organic silicon monomers (siloxanes) used in the manufacture of personal hygiene, health care and ...

  • Case study - Keeping ethanol production green

    OVERVIEW Originally published in Pollution Engineering Magazine. In an effort to reduce the world’s dependence on fossil fuels, there has been a major push towards alternatives. Ethanol has been at the forefront of this movement because it reduces greenhouse gas emissions from automobiles and its production has a positive net energy balance. The homegrown fuel also ...

  • Small project PSD cautions

    Following U.S. EPA’s promulgation of the PSD and Title V GHG Tailoring Rule, electric utilities, facilities with large industrial boilers, and other heavy industry manufacturing operations should be aware that the Prevention of Significant Deterioration (PSD) significance threshold for greenhouse gases (GHGs) may be the most stringent PSD triggering threshold for certain projects. Even ...

  • In-situ continuous emissions monitoring & regulatory compliance

    As environmental scrutiny has risen and regulation has tightened in recent years, the importance of having accurate information on the environmental performance of your power plant has increased. After all, if you want to manage something, you need to be able to measure it. The analogy is obvious; you wouldn't start a diet without first investing in a set of scales. So it is with Continuous ...

  • Is it better to burn or bury waste for clean electricity generation?

    The use of municipal solid waste (MSW) to generate electricity through landfill-gas-to-energy (LFGTE) and waste-to-energy (WTE)projectsrepresentsroughly14%ofU.S.nonhydrorenewable electricity generation. Although various aspects of LFGTE and WTE have been analyzed in the literature, this paper is the first to present a comprehensive set of life-cycle emission factors per unit of electricity ...

  • Taking Fossil Fuels to the Next Level - Standards Underpin Extraction, Processing and Distribution

    To the average person, the oil and gas industry may appear simple — a matter of literally tapping into a natural resource and distributing it to customers. Of course the matter of extraction is rarely simple, and in the case of emergent hydraulic fracturing technology, it is particularly complex and capital-intensive. In fact, the world of petroleum and natural gas extraction, distribution ...
