Organic solvents miscible with water and containing from 2 to 50% of water can be dried by passage over a molecular sieve capable of retaining water after it has been dehydrated, at a superficial velocity of less than 15 cm/min and using columns having specified lengths relative to the mass transfer zone.

Treatment of organics containing water

Coal can be extracted with high boiling aromatic oils produced by extracting the aromatic constituents of a heavy petroleum material, e.g. a bitumen residue, using a selective solvent, mixing the extract with a low-boiling aromatic solvent, adding water and separating the aromatic-containing phase and recovering said aromatic constituents. The resulting coal extract is particularly suitable for the production of electrode coke.
