This project involves the development of an optimized, bench-scale processing circuit capable of efficiently removing trace elements from, run-of-mine coals. The optimized circuit will be developed using characterization data obtained from detailed washability studies and release analyses tests conducted with several eastern U.S. coals. The optimized circuit will incorporate a variety of conventional and advanced coal cleaning processes which are believed to be the most cost-effective and commercially viable. The coal products from the optimized circuit will be further treated with complexing agents specifically designed to extract organometallic trace elements that are difficult to remove by physical cleaning operations. Finally, innovative bioremediation schemes will be investigated as a means of controlling the release of trace elements from the process waste streams. Emphasis has been placed on the development of a processing circuit which (1) maximizes the rejection of trace elements, (2) minimizes the production of coal fines which are costly to process and less marketable, and (3) minimizes the downstream impacts of the process waste streams on the environment. During the past quarter, the project work plan and all associated technical/management reports were successfully completed. In addition, three coal samples have been selected for use in the proposed test program …

During the past quarter, several key subtasks were completed. Most of the characterization tests for the Pittsburgh No. 8 coal have now been concluded. These include all activities associated with Subtasks 3.2 washability analysis, 3.3 flotation release analysis, and 3.4 SEM/image analysis. A …

The Controlled, Clean, and Stable (CCS) Design Requirements Document (DRD) contains the technically defensible and traceable functions and requirements for maintaining the Single-Shell Tank Farms in a cost effective and safe interim end state. The CCSDRD functions and requirements constitute the project characteristics that are minimally sufficient to meet the CCS mission goals.
