  • AMETEK Land reveals how power plants can better monitor their emissions

    AMETEK Land reveals in its latest engineering brief how power plant operators can benefit from opacity monitoring systems to verify that they are compliant with global and national emissions limits.   The brief, which is available at landinst.com, outlines how power-generation plant operators must measure either particulate ...

  • New webinar now available on demand - Measuring opacity and particulate emissions from combustion processes

    View our webinar where we introduce the concepts behind opacity and particulate measurement, describe the key technologies and provide detailed insight into the requirements for a successful installation. An opacity monitor provides a simple and robust means for emissions monitoring in combustion processes, but under some conditions a particulate matter (PM) monitor may be necessary. ...

  • Where Did These New Quality Assurance Requirements for Opacity Monitors Come From?

    U.S. EPA promulgated the long awaited ‘‘Quality Assurance Requirements for Continuous Opacity Monitoring Systems at Stationary Sources’’ used to demonstrate continuous compliance with opacity standards specified in new source performance standards (NSPS).  This has an effective date of November ...

  • Utilisation of pulverised coal fly-ash as filler and rice straw as fibrous raw material for manufacturing of special grade paper

    This innovative research study is based on utilisation of two solid waste materials, pulverised coal fly-ash and rice straw for manufacturing of laminate base paper. Fly-ash can prove to be a very good filler for laminate grade coloured base papers and other specialty papers where very high opacity is sought but whiteness is not important. The paper samples with 22% filler have opacity of 99.6% ...

  • Environmental impact of using biodiesel as fuel in transportation: a review

    The environmental pollution and global warming associated with the use of fossil fuels, has forced a search for alternative fuels in transportation. This paper presents a review of the use of biodiesel in CI engines and its environmental impacts. There is a significant reduction in the emission of unburned hydrocarbons, polyaromatic hydrocarbons and soot, particulate matters, carbon monoxide, ...

  • Marine Industry experience with Aalborg Industries

    Port Authorities and Governing Bodies state that a ship cannot emit smoke of >20% opacity for more than 3 minutes when in port. The IMO set similar limits for on-board incinerators. The DSL-220 Opacity Monitor has been used successfully to measure smoke emissions from diesel engines, incinerators and boilers on board ship ensuring that environmental concerns are ...

  • An analysis of extinction coefficients of particles and water moisture in the stack after flue gas desulfurization at a coal-fired power plant

    Two important factors that affect in-stack opacity—light extinction by emitted particles and that by water moisture after a flue gas desulfurization (FGD) unit—are investigated. The mass light extinction coefficients for particles and water moisture, kp and kw, respectively, were determined using the Lambert-Beer law of opacity with a nonlinear least-squares regression method. The ...

  • Israel and the bomb

    In spite of its policy of ambiguity, Israel's nuclear military capability is universally admitted. This raises the question of the underlying doctrine and the function played by the bomb in the political-military relations between Israel and its neighbours since the end of the 1950s. This paper shows that instead of contributing to deterrence, the bomb has been irrelevant (at best) or ...

  • Assessment of bagging operators exposure to with pvc airborne particulates

    The hazard potential of airborne particles is dependent on the mass concentration as well as the particle size. Particle size determines the deposition site within the respiratory tract and the subsequent health effects. Particle-size is considered from two viewpoints: The sizefraction most closely associated with the specific health effect, and the mass concentration within that size fraction. ...

  • Chemical Plant Desulfurization

    KRONOS’ facility in Leverkusen, Germany produces titanium dioxide, the most important material used by the paints and plastics industry for whiteness and opacity. When new German guidelines set maximum emission limits for SO2 in 1989, KRONOS was required to eliminate the COS from the off-gas at their titanium dioxide production facility to meet the new requirements.Complicating this application, ...
