CLEAN COKE process: process development studies. Final report. Volume III: Final process design and economics. Part 1: final process design
A process design for a CLEAN COKE commercial facility has been developed, based on information obtained from completed bench-scale and process-development studies. The design envisages a plant, based on Illinois No. 6 coal, and with a 21-year operating life. A coal feed rate of 12.43 million tons per year, raw basis (8.9 million tons MAF basis), is comprehended. Carbonization encompasses a preoxidation/drying stage followed by two stages of devolatilization to a maximum temperature of 1400/sup 0/ F. This yields a product char with residual volatile-matter and sulfur contents of 2 and 0.78 percent, respectively. The char is converted to amore »
