  • Insitu analysis of ammonia slip and water vapor using a tunable diode laser for SCR/SNCR optimization and boiler tube surveillance in power plants

    ABSTRACT Environmental Regulations driven by the 1990 Clean Air Act require Power Plants to reduce NOx emissions. SCR's and SNCR's reduce NOx emission by injecting ammonia into the combustion flue gas. which ideally reacts with the NOx to form H?0 and Nj. The efficiency of the SCR SNCR is determined by monitoring the outlet for excess NH3. referred to as NH3 slip. The flue gas sample ...

  • Area monitoring of specific ppb-level constituents utilizing process gas chromatography

    ABSTRACT In most of the industrialized countries worldwide, increasingly stringent environmental regulations require the continuous reduction of a wide range of emission sources and components. Despite local variations concerning concentrations, absolute emission quantity, target priorities and timetables, regulations typically require active compliance and proof thereof. The impact of ...

  • Methane Emissions From Terrestrial Plants

     In a recent issue of Nature Keppler et al. [2006] report the discovery that terrestrial plants emit CH4 under aerobic conditions. Until now it was thought that bacterial decomposition of plant material under anaerobic conditions, such as in wetlands and water flooded rice paddies, is the main process leading to emissions from terrestrial ecosystems. In a first attempt to upscale these ...


  • H2S Emissions Control at Geothermal Plants

    The LO-CAT® II process is used to control H2S emissions and reduce odors at geothermal power plants. Geothermal steam, considered to be a clean and environmentally friendly source of energy, is produced when water seeps into high temperature, high pressure formations below the earth's surface. The steam is brought to the surface through production wells and then expanded through a turbine to ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Experience curves for power plant emission control technologies

    This paper examines past experience in controlling emissions of sulphur dioxide (SO2) and nitrogen oxides (NOx) from coal-fired electric power plants. In particular, we focus on US and worldwide experience with two major environmental control technologies: flue gas desulphurisation (FGD) systems for SO2 control and selective catalytic reduction (SCR) ...

  • Boise Plants Benefit from Innovative Emissions Control Systems

    Fulfilling a U.S. Environmental Protection Agency (EPA) abatement agreement, Boise Building Solutions has successfully installed and implemented two innovative emissions control systems at its Elgin, Ore. plywood plant and LaGrande, Ore. particleboard plant, thanks to an alliance group that includes Pro-Environmental, M-E-C, TurboSonic and Prototech. ARTICLE REPRINTED FROM PANEL WORLD MAY 2004. ...


  • 5 Ways Wisconsin Can Reduce Power Plant Emissions

    As the U.S. Environmental Protection Agency (EPA) moves forward with standards to reduce power plant emissions—which are due to be finalized in June 2015—many states are wondering how they will comply. WRI’s fact sheet series, Power Sector Opportunities for Reducing Carbon Dioxide Emissions, examines the policies and pathways various states can use to cost-effectively meet or ...

  • The twin cities sludge-to-energy plant reduces greenhouse gas emissions

    ABSTRACTThe majority of Utilities and Agencies in the United States (U.S.) that incinerate sludge treat this practice as a disposal method and do not maximize the recovery of energy available in the sludge and hence, do not contribute to the reduction in greenhouse gas (GHG) emissions.  The Metropolitan Council Environmental Services (MCES) have used incineration at the Metro Wastewater ...

  • An application of a puff dispersion model on power plant emissions in Yatagan region, Turkey

    The present paper describes the application of the CALMET meteorological model and CALPUFF plume dispersion model to the Yatagan district to study the impact of Yatagan Power Plant emissions on the SO2 levels on December 2000 in the region. Results indicate that SO2 concentrations over the city depend strongly on advected emissions from the power plant and on the ...

  • The Whole Plant Approach to Air Emission Modeling for NESHAP Compliance

    ABSTRACTLong overlooked, the air emissions associated with biological treatment of process wastewaters continue to be further scrutinized and regulated. The common approach is to utilize EPA’s Water9 as a model to present findings and support permitting activities. It is essential when using a model that not only is the facility modeled appropriately, but also that the specific compound ...

  • The Use of Particulate Emission Monitors to Support Arrestment Plant Operation and Upkeep

    The operation of filtration type arrestment plant can be optimised by the effective use of Particulate Emission Monitors (eg Filter Leak Monitors and Filter Performance Monitors). Particulate Emission Monitors are installed throughout the broad spectrum of industrial processes to satisfy regulations (IPPC, Part B Guidance Notes, WID and LCPD) for emission limit enforcement. In addition, where ...
