Abstract: WASH WATER AND DIGESTER LIQUOR FROM A WOOD PULPING OPERATION ARE HEATED AT A TEMPERATURE IN THE RANGE OF 450*F. TO 700*F. UNDER AUTOGENEOUS PRESSURES OF ABOUT 1000 TO ABOUT 3000 P.S.I.G. FOR A PERIOD OF 0.5 MINUTE TO 6 HOURS TO FORM COKE AND A PURIFIED EFFLUENT. THE COKE IS SEPARATED FROM THE EFFLUENT AND DEWATERED. LIQUID FROM THIS DEWATERING STEP IS COMBINED WITH THE EFFLUENT AND DEPRESSURED TO FLASH VAPORIZE AND CONCENTRATE THE COMBIMED STREAM TO A SOLUBLE CHEMICALS CONCENTRATION SUITABLE FOR RECONSTITUTION AND RECYCLE TO THE PULPING OPERATION. COKE PRODUCED IN THE PROCESS MAY BE BURNED AS PLANT

FUEL AND THE ASH RECOVERED AND WORKED FOR CHEMICAL VALUES. THE LIQUID STREAM IS RECONSTITUTED FOR PULPING PURPOSES BY THE ADDITION THERETO OF PULPING CHEMICALS DERIVED, IN PART, BY BURNING THE COKE PRODUCED IN THE PROCESS.

Abstract: OILY SLUDGES ARE MIXED WITH LIGHT HYDROCARBONS DIFFERING SUBSTANTIALLY IN SPECIFIC GRAVITY THEREFROM TO SEPARATE THE SLUDGES INTO AN OIL-HYDROCARBONS PHASE AND A WATERSOLDS PHASE. THE OIL-HYDROCARBONS PHASE IS HEATED TO A TEMPERATURE ABOVE THE CRITICAL TEMPERATURE OF THE HYDROCARBONS TO REMOVE THE LIGHT HYDROCARBONS WHICH ARE RECYCLED FOR MIXING WITH ADDITIONAL SLUDGE AND THE OIL IS RECOVERED FOR FURTHER USE. THE WATER-SOLDS PHASE IS TREATED TO OBTAIN WATER OF REDUCED CHEMICAL OXYGEN DEMAND WHICH CAN BE DISCHARGED IN RECEIVING BODIES OF WATER WITHOUT POLLUTING THE SAME. THE SOLIDS SLURRIED WITH WATER WHICH ARE RECOVERED FIND UTILITY, INTER ALIA, AS LAND FILL.

Abstract: Promoting secondary recovery of crude petroleum from a subsurface reservoir by flooding the reservoir with a continuous phase liquid admixture of hydrocarbon oil and water under high temperatures and pressures at which the oil dissolves water.
