Book excerpt: Coal beneficiation as a means of reducing the sulfur and the ash content of coal is receiving increasing attention in the nation's drive to switch from the use of oil and gas to coal to meet the nation's energy requirements. However, increasingly stringent environmental controls are being placed on coal-burning plants. This paper briefly reviews current coal beneficiation practices and the advances in coal beneficiation technology that are being developed to significantly reduce the sulfur content of many high-sulfur coals. Technical and economic comparisons are presented for two currently used and two more recently developed coal beneficiation processes. The comparisons are based on conceptual process designs (developed on a common basis) for beneficiation plants designed to produce 1500 and 15,000 tons of moisture- and ash-free (MAF) coal per day. Three high-sulfur coals from significant U.S. coal-producing regions were chosen as feed coals to the conceptual plants. Results are presented for both ''grassroots'' and battery-limits-type beneficiation plants. The following conclusions may be drawn regarding the four beneficiation processes evaluated: 1. Wet mechanical beneficiation processes represent the least-cost methods. Costs for the chemical beneficiation processes are significantly higher. 2. Chemical beneficiation processes have the potential for effecting much greater sulfur reduction than the wet mechanical beneficiation processes. This is significant when considering the much lower SO/sub x/ emission levels that are being promulgated for coal-burning plants.

Available in PDF, EPUB and Kindle. Book excerpt: Concern over the effects of airborne pollution, green house gases, and the impact of global warming has become a worldwide issue that transcends international boundaries, politics, and social responsibility. The 2nd Edition of Coal Energy Systems: Clean Coal Technology describes a new generation of energy processes that sharply reduce air emissions and other pollutants from coal-burning power plants. Coal is the dirtiest of all fossil fuels. When burned, it produces emissions that contribute to global warming, create acid rain, and pollute water. With all of the interest and research surrounding nuclear energy, hydropower, and biofuels, many think that coal is finally on its way out. However, coal generates half of the electricity in the United States and throughout the world today. It will likely continue to do so as long as it's cheap and plentiful [Source: Energy Information Administration]. Coal provides stability in price and availability, will continue to be a major source of electricity generation, will be the major source of hydrogen for the coming hydrogen economy, and has the potential to become an important source of liquid fuels. Conservation and renewable/sustainable energy are important in the overall energy picture, but will play a lesser role in helping us satisfy our energy demands today. Dramatically updated to meet the needs of an ever changing energy market, Coal Energy Systems, 2nd Edition is a single source covering policy and the engineering involved in implementing that policy. The book addresses many coal-related subjects of interest ranging from the chemistry of coal and the future engineering anatomy of a coal fired plant to the cutting edge clean coal technologies being researched and utilized today. A 50% update over the first edition, this new book contains new chapters on processes such as CO2 capture and sequestration, Integrated Gasification Combined Cycle (IGCC) systems, Pulverized-Coal Power Plants and Carbon Emission Trading. Existing materials on worldwide coal distribution and quantities, technical and policy issues regarding the use of coal, technologies used and under development for utilizing coal to produce heat, electricity, and chemicals with low environmental impact, vision for utilizing coal well into the 21st century, and the security coal presents.
