  • A Critical Evaluation of the South African Air Quality Offsets Guideline

    There is wide recognition in South Africa to the link between the quality of life and quality of the air we breathe. The Department of Environmental Affairs (DEA) attempts to improve air quality through two key regulatory tools; emission limits, which regulate the maximum concentration of certain pollutants permissible within certain, ‘listed’ industrial stacks or vents, and ambient ...

  • Simulation of plume dispersion using different stack configurations and meteorological inputs

    The application of CALMET/CALPUFF modelling system is well known, and several validation tests were performed until now; however, most of them were based on experiments with a large compilation of surface and aloft meteorological measurements, not always available. Also, the use of an operational large smokestack as tracer source is not so usual. In this work, CALPUFF model is applied to ...

  • White Paper: ANSI N13.1-2011 Stack Sampling Considerations

    Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the authority over the monitoring of these ...

  • 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 ...

  • Determination of TOC in stack through the innovative FID analyser easy to carry - Case Study

    PROBLEM: The industrial chimney's emissions of Volatile Organic Compounds (VOCs) are becoming issues of global importance and to have an accurate knowledge about how to test VOC turns into a strategic issue. VOC emissions are quantified and monitored according to standard EN 12619, using FID analyzer which uses hydrogen and other reference gases in ...

  • Theory, Modeling, and Measurements of Gas Plumes

    Abstract Spectroscopic measurements of infrared CO2 transitions in gas plumes are reported, and evaluated for their potential to yield a reliable remote sensing technique for determination of plume temperature. Measurements were made on two types of plumes: a sideways-directed plume from a vehicle exhaust, and a stack plume from a propane-burning portable plume generator. Modeling of CO2 ...

  • Grana-Localized Proteins, RIQ1 and RIQ2, Affect the Organization of Light-Harvesting Complex II and Grana Stacking in Arabidopsis

    Abstract Grana are stacked thylakoid membrane structures in land plants that contain photosystem II (PSII) and light-harvesting complex II proteins (LHCIIs). We isolated two Arabidopsis mutants, reduced induction of non-photochemical quenching (riq1 and riq2), in which stacking of grana was enhanced. The curvature thylakoid 1a curt1a) mutant was previously shown to lack grana structure. ...

  • Air emissions impact measurements at a perchloroethene remediation site

    As part of an U.S. EPA time critical removal action, an air monitoring system was established to measure real-time impacts of perchloroethene (PCE) on the surrounding areas. The soils and groundwater beneath the site (located in West Fargo, North Dakota) were treated using in situ heating of soil and groundwater, with the produced vapors collected using conventional vapor extraction. In order ...

    In the center of the program window, we will draw and we will calculate the different polluting processes. We can draw using two different planes: parallel to the land surface (XY) and perpendicular to the land surface (XZ). There is a grid in the XY-plane. The coordinate origin is on the left bottom corner (X=0, Y=0) in XY-planes (parallel to the land surface). In addition, the coordinate origin ...
