- W2293629114 abstract "The number of coal preparation plants operating and/or under construction in the coalfields of the world has kept up with the huge demand for coal during the present worldwide energy crisis. The plants cover a wide spectrum in both range of capacity and levels of cleaning. The plants vary in capacity from 100 tons per hour to as high as 3,000 tons per hour. Regarding capacities, there seems to be a trend in two opposite directions, either toward the construction of small tonnage plants, which are of modular design and frequently portable, or to the building of extremely large central plants Both have their applications. In the USA, research is still emphasizing desulphurization. It is recognized that even with the more stringent EPA regulations necessitating some type of power station stack emission cleanup, coal preparation in washeries ahead of the power plants is desirable, even if it cannot remove all the sulphur required to meet the final regulations. Preparation not only removes a large share of the pyritic content, but also diminishes fly ash loads (giving higher calorific values and lowered transportation costs). The US Department of Energy (DOE) plans to spend between $10,000,000 and $15,000,000 in preparation research in more » 1980 to develop near-term coal preparation processes. « less" @default.
