This study in 3 volumes concerns three sequential coal processing operations: beneficiation, gasification, and transportation. In the final step, clean coal is transported pneumatically by means of a fuel gas stream produced during gasification. The three processes are a means of providing clean, reasonably priced fuels to the major demand areas of the United States. Three beneficiation techniques were considered, dry air table cleaning, wet deep cleaning through heavy media cyclone and floatation cell systems, and a conceptual air classification/screening system. The BI-GAS process was the coal gasification process considered. This process produces a fuel gas of 450 Btu/SCF. A pneumatic transport system was devised for long distance (300 miles) transport of beneficiated coal and clean fuel gas. The system was analyzed for various pipe diameters, flow rates, coal particle sizes, coal to gas mass ratios, and operating pressures. A representative end of pipeline fuel cost of $2 to $4 per million Btu was predicted by this study. Alternative modes of transport also were considered for comparison with pneumatic transport. They were unit train and slurry pipeline systems. An economic systems analysis was developed and transport tariffs of all the systems obtained. This study indicates that the clean coal and gas fuel mixture can be delivered to the Philadelphia-Wilmington area from West Virginia (300 miles) at 20 year average costs of from $2.10 to $3.60 per MMBtu if the product gas is used to transport the beneficiated coal and the raw coal is available at the mine mouth for $10.00 to $25.00 per ton, respectively.
