Available in PDF, EPUB and Kindle. Book excerpt: The design criteria for each unit operation have been developed based upon a number of variables. These variables, at this time, are based upon the best engineering design information available to industry. A number of assumptions utilized in the design criteria are uncertain. The uncertainties of inert atmospheres for grinding and flotation as well as pyrite depressants were answered by the Surface Control Project. It was determined that inerting was not required and no ''new'' reagents were presented that improved the flotation results. In addition, Tasks 5 and 6 results indicated the required reagent dosage for conventional flotation and advanced flotation. Task 5 results also indicated the need for a clean coal, thickener, the flocculent dosages for both the clean coal and refuse thickeners, and final dewatering requirements. The results from Tasks 5 and 6 and summarized in Task 7 indicate several uncertainties that require continuous long duration testing. The first is the possibility of producing a grab product for both the Pittsburgh and Illinois No. 6 coals in conventional flotation. Second what does long-term recirculation of clarified water do to the product quality? The verification process and real data obtained from Tasks 5 and 6 greatly reduced the capital and operating costs for the process. This was anticipated and the test work indeed provided confirming data.

This book was released on 1992 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: The changes made to the Coal Cleaning Simulator during this period were mostly aimed at correcting problems found during the flowsheet validations. one modification was made to the washability interpolation. Prior to interpolation, the feed size distribution is preprocessed by a subroutine which resets the size intervals. That subroutine was changed to ensure that standard screen sizes be used for the size intervals, with only the topsize being the actual user specified size limit. This should prevent problems such as the size range being much wider than that provided by the user (previously, this subroutine would add fine size intervals to the input size range, in some cases). Another change made was the modification of the heavy media cyclone water balance algorithm. Because of the internal calculations of both the amount of media and makeup water required, the water balance was not being made correctly in the case where a feed that was too dilute. The report writer for this model was also modified in order to correctly label the material balances reported. Other changes made were the addition of fifteen coals to the Coal Property Databank, and the referencing of utilities in the screen cost models for operating cost calculations. Finally, a number of problems had been reported for CCS cost models. These were related to discrepancies between UOS block sizing calculations and cost block sizing calculations, and utilities (horsepower requirement) calculations. The corrections were applied to the latest CCS version.

Available in PDF, EPUB and Kindle. Book excerpt: Work completed produced the criteria for additional engineering analysis, computation and detailed experimental benchscale testing for areas of uncertainty. The engineering analysis, computation, bench-scale testing and component development was formulated to produce necessary design information to define a commercially operating system. In order to produce the required information by means of bench-scale testing and component development, a uniform coal sample was procured. After agreement with DOE, a selected sample of coal from those previously listed was secured. The test plan was developed in two parts. The first part listed procedures for engineering and computational analyses of those deficiencies previously identified that could be solved without bench scale testing. Likewise, the second part prepared procedures for bench-scale testing and component development for those deficiencies previously identified in Task 3.

Available in PDF, EPUB and Kindle. Book excerpt: This document a quarterly report prepared in accordance with the project reporting requirements covering the period from July 1, 1992 to September 30, 1992. This report provides a summary of the technical work undertaken during this period, highlighting the major results. A brief description of the work done prior to this quarter is provided in this report under the task headings. 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. The conceptual flowsheet must be examined to identify critical areas that need additional design data. This data will then be developed using batch and semi-continuous bench scale testing. 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. The conceptual flowsheet will be revised based on the results of the bench scale testing and areas will be identified that need further larger scale design data verification, to prove out the design.

Available in PDF, EPUB and Kindle. Book excerpt: A study conducted by Pittsburgh Energy Technology Center of sulfur emissions from about 1,300 United States coal-fired utility boilers indicated that half of the emissions were the result of burning coals having greater than 1.2 pounds of SO2 per million BTU. This was mainly attributed to the high pyritic sulfur content of the boiler fuel. A significant reduction in SO2 emissions could be accomplished by removing the pyrite from the coals by advanced physical fine coal cleaning. An engineering development project was prepared to build upon the basic research effort conducted under a solicitation for research into Fine Coal Surface Control. The engineering development project is intended to use general plant design knowledge and conceptualize a plant to utilize advanced froth flotation technology to process coal and produce a product having maximum practical pyritic sulfur reduction consistent with maximum practical BTU recovery.
