DOI:https://doi.org/10.2172/7118158· OSTI ID:7118158

This is a report of the results obtained from the operation of an integrated test circuit for the Molten-Caustic-Leaching (MCL or Gravimelt) process for the desulfurization and demineralization of coal. The objectives of operational testing of the 20 pounds of coal per hour integrated MCL test circuit are: (1) to demonstrate the technical capability of the process for producing a demineralized and desulfurized coal that meets New Source Performance Standards (NSPS); (2) to determine the range of effective process operation; (3) to test process conditions aimed at significantly lower costs; and (4) to deliver product coal.
