Abstract
IN PHASE I, A PRELIMINARY ENGINEERING DESIGN AND COST ESTIMATE WILL BE PREPARED FOR A ONE TON PER HOUR (TPH) SKID-MOUNTED INSTRUMENT-CONTROLLED COAL CLEANING PILOT UNIT TO BE BUILT AND OPERATED IN PHASE II. THE PILOT UNIT WILL CONSIST OF A MODIFIED AIR SWEPT RING/ROLLER PILOT MILL WITH ATTACHED MAGNETIC SEPARATOR. THE UNIT IS DESIGNED FOR SEPARATION OF PYRITES AND OTHER MINERALS FROM THE INTERNAL CIRCULATING LOAD OF THE ROLLER MILL WHEN PREPARING MINUS 200 MESH COAL FOR DIRECT FIRING. THE UNIT WILL BE USED IN PHASE II TO DEMONSTRATE THE EFFICIENCY OF THE RING/ROLLER MILL-MAGNETIC SEPARATOR COMBINATION IN PREPARING LOW SULFUR AND LOW ASH PULVERIZED COAL. THE TEAM WILL ALSO PREPARE A CONCEPTUAL ESTIMATE OF THE COST TO BUILD OR TO RETROFIT A COMMERCIAL PRE-COMBUSTION RAW COAL DESULFURIZATION UNIT CONSISTING OF A DRY MAGNETIC SEPARATOR ATTACHED TO AND TREATING A PORTION OF THE HIGH SULFUR INTERNAL CIRCULATING LOAD OF A 50 TPH PULVERIZER PRODUCING 70%-80% MINUS 200 MESH CLEAN COAL.
