Abstract

Clean water and dry, oil-free solids are recovered from aq. solids by first mixing the solids with a low viscosity, relatively-volatile, water-immiscible light fluidising oil (A) boiling in the range 150-550 deg.F to form a mixt. which remains fluid and pumpable after removal of water. Mixt. is heated to remove all the water and same (A), and the vapour condensed, then the condensate sepd. into water and (A) fractions. Residual solids (slurried in (A)) are sepd. to remove same (A) then treated directly with hot, inert blowing gas (combustion gas , N2 or CO2) to evaporate (A), leaving anhydrous solids. (A) recovered from the various stages are recycled from treatment of more aq. solid. Pref. blowing gas is also recycled (after removal of (A) vapour).
