  • External losses in high-bypass turbo fan air engines

    The external irreversible losses of air engines, due to equilibration of the hot and fast exhaust with the environment, are discussed based on the second law of thermodynamics. The effect of the bypass ratio on thermomechanical exergy destruction in the exhaust stream is demonstrated. The analysis gives a strong motivation for the use of high bypass turbo fan engines in modern aircraft.Keywords: ...

  • Exergy analysis of process heaters

    A thermodynamic analysis is proposed to investigate the entropy generation in process heaters. It is found that the major portion of the exergy losses occur in the stack. It is also found that the excess air decreases the first law efficiency while the second law efficiency remains nearly constant. Although the first law efficiency is found to be of the order of 70-90%, the second law efficiency ...

  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • A new vision for clean air

    When President George H.W. Bush signed into law the Clean Air Act Amendments (CAAA) of 1990, he put in place a precedent-setting statute that completely revamped our nation’s approach to improving air quality. That statute was an earnest commitment to environmental protection; the comprehensive air pollution control strategy established in it provided state and local regulators with tools to make ...

  • High-Tech Filters

    The current economic situation of the cement industry creates sensitivity regarding off-times and process stability. More stringent air-pollution laws, especially when using waste-derived fuels, are drawing more attention to the off-gas cleaning facilities, usually bag filters. This article does not deal with electrostatic precipitators - as even they have well known disadvantages. By using more ...

  • US Federal Air Marshal Badge

    The Federal Air Marshal Service (FAMS) is a United States federal law enforcement agency under the supervision of the Transportation Security Administration (TSA) of the United States Department of Homeland Security (DHS). The Air Marshal Service is meant to promote confidence in civil aviation by effectively deploying federal air marshals (FAMs) to detect, deter, and defeat hostile acts ...

  • Development of a low-rise industrial source dispersion model

    In Japan, with amendment of the Air Pollution Control Law in May 1996, various substances, including benzene and trichloroethylene, were newly designated as hazardous air pollutants, and environmental standards were established. In this situation, it is necessary to develop a dispersion model that is applicable to environmental impact assessment of industrial areas with a complex of factory ...

  • Climate change law and litigation in the aftermath of Massachusetts v. EPA

    The case of Massachusetts v. EPA, decided in April 2007 by the U.S. Supreme Court, may be the most important case in the history of environmental law. The author says the Environmental Protection Agency's air program personnel are now straining to grapple with new, enormously consequential legal and policy questions in the aftermath of this ...

  • Passive samplers for air quality monitoring in a Brazilian university

    The aim of this paper was to evaluate the applicability of passive samplers for the monitoring and diagnosis of air pollution at Passo Fundo University, focusing on atmospheric pollutants NO 2 and O 3 . The samplers were built in accordance with already verified methodologies and were placed in several locations in the university campus, namely: energy generator, pool heating boiler, ...

    Micro Pulse LiDAR is an effective tool for monitoring and measuring dust and emissions produced by mining operations. Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining ...

  • Succeeding in a carbon-constrained world

    The author details the inevitability of a stronger U.S. climate change policy, the increasing business leadership on climate issues, the factors that influence corporate climate strategies, and the effective business strategies that address climate change. Although it may yet be several years before the United States enacts greenhouse gas (GHG) regulation, a profound transformation is beginning ...

  • Preserving the SO2 market - review the recent challenge mounted by New York State against the US market in sulphur dioxide allowances

    The US District Court for the Northern District of New York recently struck down a New York State law that affected the US market for sulphur dioxide (SO2) allowances. In Clean Air Markets Group v Pataki,* the court ruled that New York’s law violated the Supremacy and Commerce Clauses of the US Constitution. New York enacted the anti-trading law in May 2000 with the purported goal of reducing ...

  • Big Clear Sky – A short history of the Clean Air Act

    Major advances over 50 years have led to cleaner air and groundbreaking technology. The detrimental impact of industrialization to air quality in the United States went unchecked through federal legislation for most of the first half of the 20th Century. But following the 1948 industrial catastrophe in Donora, Pennsylvania – where a cloud of smog killed 20 and injured thousands – regulation of ...

  • Differential impacts of smoke-free laws on indoor air quality

    The authors assessed the impacts of two different smoke-free laws on indoor air quality. They compared the indoor air quality of 10 hospitality venues in Lexington and Louisville, Kentucky, before and after the smoke-free laws went into effect. Real-time measurements of particulate matter with aerodynamic diameter of 2.5 µm or smaller (PM2.5) were made. One Lexington establishment was excluded ...

  • Estimation and parameterisation of the influence of turbulent regimes on pollution characteristics in the PBL

    An approach which includes joint use of resistance laws, PBL, and diffusion models, coordinated with the method of moments has been developed. The influence of a set of turbulent regimes, parameterised by external parameters in similarity format, on diffusion processes in PBL has been studied on this basis.Keywords: resistance laws, turbulence, turbulent regimes, air quality, air pollution, ...

  • 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, ...

  • Legal developments related to greenhouse gas emissions

    The prospects for new regulations on greenhouse gas emissions have evolved from a possibility to an inevitability, according to the authors of this article. They say the greatest potential for new regulations on greenhouse gas emissions is emerging from existing laws--most particularly, the Clean Air Act. The authors, noting that state regulatory efforts and successes in the courts have set the ...
