(Engineering development of advanced physical fine coal cleaning technology: Froth flotation)
The Department of Energy (DOE) awarded a contract entitled Engineering Development of Advanced Physical Fine Coal Cleaning Technology -- Froth Flotation,'' to ICF Kaiser Engineers with the following team members, Ohio Coal Development Office, Babcock and Wilcox, Consolidation Coal Company, Eimco Process Equipment Company, Illinois State Geological Survey and Virginia Polytechnic Institute and State University. The overall project scope of the engineering development project is to conceptually develop a commercial flowsheet to maximize pyritic sulfur reduction at practical energy recovery values. This is being accomplished by utilizing the basic research data on the surface properties of coal, mineral matter and pyrite obtained from the Coal Surface Control for Advanced Fine Coal Flotation Project, to develop this conceptual flowsheet. In addition to actual bench scale testing, other unit operations from other industries processing fine material will be reviewed for potential application and incorporated into the design if appropriate. This report describes progress on the unit operation design and process performance data required to (1) reduce or eliminate the technical and engineering uncertainties of the preliminary 20TPH advanced location semi-works plant and (2) design, build and operate a 2--3 TPH advanced flotation POC module; raw coal characterization; advanced flotation round robin; bench scale process testing; and component and unit operations development. 8 refs., 18 figs., 5 tabs.
