- Work this quarter focused on the development of the engineering design specifications for the ET Test Circuit. Process flowsheets and detailed equipment specifications were finalized. Based on this information, bid packages were assembled and purchase orders were issued for all of the necessary process equipment. The design and procurement information is summarized in the ET Circuit Design Report submitted to the DOE's COR this quarter. Final drafts of the ET Circuit - System Safety Analysis, Nuclear Density Gauge - System Safety Analysis and Operating Manual/SOP were also completed and submitted to the COR this quarter. Preliminary characterization studies were also initiated this quarter. Tests were conducted to determine the grinding conditions required to achieve the desired particle size distributions for the characterization work. Flotation release analysis tests were conducted on both the Pittsburgh [number sign]8 and Illinois [number sign]6 seam coals as a function of grind size. The primary objective of the proposed work is to design, install, and operate an advanced fine coal processing circuit combining the Microcel and Multi-Gravity-Separator (MGS) technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column effectively removes ash-bearing mineral matter, while the MGS efficiently removes coal-pyrite composites. By combining both unit operations into a single processing circuit, synergistic advantages can be gained. As a result, this circuit arrangement has the potential to improve coal quality beyond that achieved using the individual technologies.
