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: 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.

Download or read book Engineering Development of Advanced Physical Fine Coal Cleaning for Premium Fuel Applications. Quarterly Technical Progress Report No. 3, April--June 1993 written by and published by . This book was released on 1993 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is a major step in the Department of Energy's program to show that ultra-clean coal-water slurry fuel (CWF) can be produced from selected coals and that this premium fuel will be a cost-effective replacement for oil and natural gas now fueling some of the industrial and utility boilers in the United States. The replacement of oil and gas with CWF can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the CWF. This cost-share contract is a 48-month program which started on September 30, 1992. This report discusses the technical progress made during the quarter from April 1 to June 30, 1993. The project has three major objectives: (1) the primary objective is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to coal-water slurry fuel for premium fuel applications. The fine coal cleaning technologies are advanced column flotation and selective agglomeration. (2) a secondary objective is to develop the design base for near-term application of these advanced fine coal cleaning technologies in new or existing coal preparation plants for efficiently processing minus 28-mesh coal fines and converting this to marketable products in current market economics; and (3) a third objective is to determine the removal of toxic trace elements from coal by advance column flotation and selective agglomeration technologies.

Available in PDF, EPUB and Kindle. Book excerpt: In order to develop additional confidence in the conceptual design of the advanced froth flotation circuit, a 2-3 TPH Proof-of-Concept (POC) facility was necessary. During operation of this facility, the ICF KE team will demonstrate the ability of the conceptual flowsheets to meet the program goals of maximum pyritic sulfur reduction coupled with maximum energy recovery on three DOE specified coals. The POC circuit was designed to be integrated into the Ohio Coal Development's facility near Beverly, Ohio. OCDO's facility will provide the precleaning unit operations and ICF KE will add the advanced froth flotation circuitry. The work in this task will include the POC conceptual design, flowsheet development, equipment list, fabrication and construction drawings, procurement specifications and bid packages and a facilities.

Book excerpt: This project is a step in the Department of Energy's program to show that ultra-clean fuel can be produced from selected coals and that the fuel will be a cost-effective replacement for oil and natural gas now fueling boilers in this country. The replacement of premium fossil fuels with coal can only be realized if retrofit costs are kept to a minimum and retrofit boiler emissions meet national goals for clean air. These concerns establish the specifications for maximum ash and sulfur levels and combustion properties of the ultra-clean coal. The primary objective is to develop the design base for prototype commercial advanced fine coal cleaning facilities capable of producing ultra-clean coals suitable for conversion to coal-water slurry fuel. The fine coal cleaning technologies are advanced column flotation and selective agglomeration. A secondary objective is to develop the design base for near-term commercial integration of advanced fine coal cleaning technologies in new or existing coal preparation plants for economically and efficiently processing minus 28-mesh coal fines. A third objective is to determine the distribution of toxic trace elements between clean coal and refuse when applying the advance column flotation and selective agglomeration technologies. The project team consists of Amax Research & Development Center (Amax R & D), Amax Coal industries, Bechtel Corporation, Center for Applied Energy Research (CAER) at the University of Kentucky, and Arcanum Corporation.

Available in PDF, EPUB and Kindle. Book excerpt: The construction of the DOE POC at the OCDO facility continued through this entire quarter. By the end of the quarter approximately 90% of all of the construction had been completed. All equipment has beeninstalled, checked for mechanical and installation and operated from a local pushbutton. During this quarter a review of items to be completed for start-up was compiled. This information was then presented to the construction subcontractors and agreement was concluded that all items will be completed and operational for processing coal by February 1, 1993. There are still several items that were not on site for installation during this quarter. These items are the flocculant controls supplied by Westec Engineering, Inc., and the discharge valve for the hyperbaric filter supplied by KHD. Neither of these items will prevent start-up. The flocculants can be manually controlled and provisions are all ready provided to bypass the hyperbaric filter to the Sharpels high-G centrifuge. Both of these items are scheduled for delivery in mid-January.
