    Extending the Lifespan and Improving the Efficiency of Matured FGD Systems | Presented at Coal-Gen 2013

    In January 2010, a project was undertaken to upgrade the existing flue gas desulfurization (FGD) systems and FGD waste handling systems at PacifiCorp Energy’s Hunter and Huntington Stations in order to meet permitted SO2 emission requirements and extend the life of the waste products landfill disposal site.

    Maximizing the Effectiveness of Precipitator Inspections
    | WPCA | Dumbauld, Lugar

    Much has been documented about the benefits of conducting both a dirty and clean internal precipitator inspection. In addition to these physical inspections, another important diagnostic tool that should be a key component of the inspection is the documenting and evaluating of the electrical characteristics of the precipitator. When this is done, it is usually in the form of observing/recording transformer-rectifier (TR) electrical readings during air-load energization of the ESP. Read More...

    CleanStack for SO3 mitigation

    This paper presents the results of a full-scale demonstration of a proprietary technology for the reduction of sulfur trioxide (SO3) emissions from coal-fired power plant flue gases. Marsulex Environmental Technologies, the Energy & Environmental Research Center, and ALSTOM Power, Inc., Air Preheater Company developed the technology, trademarked CleanStack, jointly. Read More...

    Wet FGD Performance Upgrade Case Study at B.L. England Unit 2

    RC Cape May Holdings LLC’s B.L. England Station Unit 2 was retrofitted with a limestone wet flue gas desulfurization system (FGD) that was placed in service in 1994 in order to comply with the 1990 Clean Air Act. An Administrative Consent Order (ACO) issued in 2006 by the New Jersey Department of Environmental Protection that required the SO2 removal efficiency to be increased to 97% from the original performance level of ˜93% while firing the design 3.2% sulfur bituminous coal by May, 2010. Read More...

    Operating Experience of CFB-FGD Technology with Novel Humidification Technology | August 2010 | Presented at Coal-Gen 2010

    Applications of circulating fluidized bed (CFB) semi-dry flue gas desulfurization (FGD) technology are increasing globally on coal-fired boilers, MSW incinerators, and other sources because of water saving characteristics, the ability to control SO2 emissions comparable to traditional wet FGD and, in addition, providing simultaneous removal of SO3, acid gases and particulate. Read More...

    Operational Experience of Commercial, Full Scale Ammonia-based Wet FGD for Over a Decade | August 2009 | Presented at Coal-Gen 2009

    A novel and commercially viable process for flue gas desulfurization (FGD), using ammonia as a reagent and producing commercial grade ammonium sulfate (AS) crop fertilizer, was developed by General Electric Environmental Services, Inc. (GEESI) in the early 1990’s and subsequently acquired by Marsulex Environmental Technologies (MET). The first field pilot of this technology was successfully executed at Dakota Gasification Company’s (DGC) Synfuels Plant and led to a subsequent full-scale commercial installation of 350 MWe at that site. Read More...

    Ammonium Sulfate WFGD Technology, July 2007

    Marsulex Environmental Technologies (MET) has developed an effective ammonia scrubbing technology that removes sulfur dioxide (SO2) from boiler flue gases and produces high-value ammonium sulfate (AS) fertilizer. The AS scrubbing system uses proven wet flue gas desulfurization (WFGD) equipment and therefore can achieve the same high reliability of the more traditional limestone-based WFGD. Read More...

    AS Technology Significantly Cuts Power Generation Costs, Sept 2005

    Utility deregulation is a reality. Successful generators of electricity will need to significantly lower bus bar cost of power by a creative combination of low cost fuel and the application of Marsulex Environmental Technologies’ (MET’s) patented Ammonia Scrubbing Technology. Because fuel constitutes the largest component of generation cost, substantial reductions can be achieved by firing low cost fuels such as high sulfur coal or petroleum coke. This option has been historically handicapped by sulfur dioxide emission limitations and related economics. Read More...
