  • EVALUATION OF STRATEGIES FOR MERCURY MACT COMPLIANCE

    On December 15, 2003, the United States Environmental Protection Agency (U.S. EPA) proposed a rule with two alternatives to permanently reduce mercury (Hg) emissions from power plants. Under one alternative, which is the focus of this paper, the utilities would install controls known as Maximum Achievable Control Technologies (MACT) under section 112 of the Clean Air Act (CAA). The proposed rule ...

  • Minimization of Major Air Pollutants from Sewage Sludge Fluid Bed Incinerators

    ABSTRACT Emissions of major air pollutants including carbon monoxide (CO), nitrogen oxides (NOx) and mercury (Hg) were studied at two sewage sludge fluidized bed combustion (FBC) plants. Both the North West Bergen (NWB) County Utility Authority and the Little Miami (LM) plants have air pollution control systems (APCS) that are of the wet type. Various operating conditions such as temperature, ...

  • How the federal utility MACT rule may affect US businesses

    The final standards for hazardous air pollutant (HAP) emissions from electric generating units (EGUs), one of the last industries to be regulated by MACT, was just published in the Federal Register on February 16 and officially goes into effect on April 16, 2012. The rule (“Utility MACT”) had been long awaited; the USEPA began developing it 11 years ago. According to federal NESHAP, ...


  • Smelter gas cleaning one vessel from the quench to the drying tower

    Base metals such as zinc, lead and copper are all found in nature bound with sulphur as sulphite minerals: sphalerite (ZnS), galena (PbS), several copper minerals, silver (found as acanthite Ag2S), and, along with other precious metals. Processing of the metals invariably leads to sulphur dioxide (SO2) formation. Other metal processing, such as aluminum from bauxite ore [Al(OH)3] which contains ...

  • Moisture Audits & Analyser Performance Assessments at Woodside, Karratha - Case Study

    Woodside had been experiencing intermittent blockages in 4/5 S1406 LNG trains since September 2008 and had been unable to pinpoint the source of the problems. Repeated hydrate formations were leading to reduced productivity and the existing process monitoring instrumentation had failed to confirm moisture breakthrough on the beds. The site's existing Panametrics portable moisture analysers had ...

  • Wet Electrostatic Precipitation Demonstrating Promise for Fine Particulate Control

    Editor’s Note: Part l of this two-part feature on wet electrostatic precipitation (wet ESPs) outlines the need for multi-pollutant air pollution control technologies, the basics of wet and dry electrostatic precipitation, the ability of wet and dry ESPs to treat fine particulate, and the use of wet ESP technology at Northern States Power Company’s Sherco Station. Part II will explore the key ...


  • Wet electrostatic precipitators offer cost-effective solution for HZL - Case Study

    An array of complex air pollution issues places the metallurgical industry among the largest potential sources of pollutants, and one of the most tightly regulated industrial sectors. One fully integrated, nonferrous metal producer in India, however, is demonstrating that a company with a determined commitment to environmental protection, energy efficiency and sustainability can succeed in ...

  • Incineration

    Introduction: High temperatures, 870 to 1,200 °C (1,400 to 2,200 °F), are used to volatilize and combust (in the presence of oxygen) halogenated and other refractory organics in hazardous wastes. Often auxiliary fuels are employed to initiate and sustain combustion. The destruction and removal efficiency (DRE) for properly operated incinerators exceeds the 99.99% requirement for hazardous waste ...
