    Fortunately, most of the sulfur is already removed from fuels during refining through a remarkable chemical process called hydrodesulfurization. The sulfur gets stripped from the fuel in the form

  • COAL-FIRED POWER PLANTS:SULFUR DIOXIDE REMOVAL

    The best established method of removing most of the sulfur from the flue gas of a power plant is with a flue-gas desulfurization (FGD) unit, also called a wet scrubber. The FGD unit comprises a specially constructed, tall chamber through which the flue gas passes.

  • How to Remove Sulphur from Coal

    Reducing the inorganic sulfur in coal to tolerable limits by physical beneficiation, including flotation, as now practd, still is relatively inefficient and has not kept pace with the more sophisticated physical beneficiation approaches employed by the nonfuel minerals industry in general. As one phase of a broad program conducted by the Mineral Resources Institute on the sampling and

  • SELECTIVE REMOVAL OF ORGANIC SULFUR FROM COAL

    16/05/2007· Desulfurization of coal involves the removal of both the inorganic and organic forms of sulfur. Several physical methods are availe for the removal of inorganic sulfur which is normally represented by pyritic and sulfatic sulfur. Removal of organic sulfur requires the use of chemical cleaning methods.

  • Emissions of sulfur trioxide from coal-fired power plants

    Emissions of sulfur trioxide (SO3) are a key component of plume opacity and acid deposition. Consequently, these emissions need to be low enough to not cause opacity violations and acid deposition. Generally, a small fraction of sulfur (S) in coal is converted to SO3 in coal-fired combustion devs such as electric utility boilers.

  • The Reduction of Mercury and Sulfur Dioxide Emissions

    The primary use will be for the removal of mercury from coal-fired utility plant and municipal waste incinerator emissions to reduce emission levels to meet new and future EPA regulations. This is expected to cause a major reduction of anthropogenic mercury emissions in the United States and worldwide. Capital costs are predicted to be minimal, and when used in conjunction with a wet flue gas

    A process for reducing the sulfur and ash content of coal wherein coal particles are treated in an aqueous slurry with a minor amount of hydrocarbon oil to form coal-oil aggregates. The coal-oil aggregates are separated from ash and mineral matter in the slurry by dissolved gas flotation. Optionally, the coal particles may be treated with a conditioning agent prior to the aggregation step.

    Abstract. The thermophilic, reduced-sulfur, iron-oxidizing bacterium Sulfolobus acidocaldarius was used for the removal of sulfur compounds from coal. The inclusion of complex nutrients such as yeast extract and peptone, and chemical oxidizing agents, 0.01 M FeCl 3 into leaching medium, reduced the rate and the extent of sulfur removal from coal. The rate of sulfur removal by S. acidocaldarius
