Bench-scale testing of the Multi-Gravity separator in combination with Microcel. Third quarterly report, April 1, 1993--June 30, 1993
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. Work this quarter primarily focused on procurement and fabrication of the required process equipment. All fabrication work is underway and is expected to be completed prior to the installation deadline. Delays in the existing project within the Pittsburgh Energy Technology Center`s Coal Preparations Process Research Facility have resulted in a shift in the original project schedule. A new installation date (June 28, 1993) has been established by DOE/PETC. The overall project schedule has been adjusted accordingly. Revisions to ESH subject plans were also completed during this quarter. Based on these plans, the ESH permitting procedure has been initiated by the contracting officer`s representative. The subject plans and circuit will be modified, if necessary, to reflect any changes suggested by DOE. It is anticipated that the ESH permit will be issued in the early part of the third quarter. Preliminary characterization studies continued this quarter. Modifications were made to the centrifugal washability procedure to minimize time material requirements. Using the modified procedure, tests were conducted on both the Pittsburgh No. 8 and Illinois No. 6 seam coals as a function of particle size.
