Abstract
Substantially dry coal fines are fed into a pressurized zone by slurrying coal fines with a liquid, water-miscible, volatile organic solvent to form a pumpable slurry, pressurizing the slurry, removing and recycling the organic solvent component of the liquid phase of the slurry, thermally drying the pressurized fines and transporting the dried, pressurized fines into the pressurized zone.
