Abstract: SEPTIC BIOLOGICAL WASTES, INCUDING BOTH COMMERCIAL AND INDUSTRIAL WASTES PRODUCED IN ARCTIC CLIMATES, ARE RENDERED STERILE AND SUITABLE FOR DISCHARGE BY BEING PASSED TO A PRIMARY SETTLER WHERE SOLIDS CONTAINED THEREIN ARE SEPARATED FROM CLEAR EFFLUENT. THE SOLIDS ARE COKED IN THE LIQUID PHASE AND THE RESULTING COKE IS SEPARATED FROM THE LIQUID. THE DECOKED LIQUID IS MIXED WITH THE EFFLUENT FROM THE PRIMARY SETTLER AND THE RESULTING MIXTURE IS AIR OXIDIZED.

Abstract: OIL SPILLS ARE REMOVED FROM THE SURFACE OF A BODY OF WATER BY CONTACTING THE OIL WITH A COAGULATING AMOUNT OF A COAGULANT SUCH AS ASPHALT AND MIXTURES OF WAX OR ASPHALT WITH ANTI-CAKING AGENTS. ENOUGH COAGULANT IS USED TO FORM A FLOATING, SEMI-COLID MASS WITTH THE OIL. THE COAGULANT MAY BE USED IN FINELY DIVIDED FORM OR IN A MOLTEN STATE.

Abstract: Closed circuit process for treating waste liquors, such as spent sulfite liquors from wood digestion by coking the liquors in the liquid phase under pressure under turbulent flow conditions to form coke and a clear effluent of low chemical oxygen demand. In the process, a heat exchange zone, a coking zone, a steam-and flue gas-producing zone, an absorbing zone, a wood digesting zone and a kilning zone are provided and interconnected by suitable conduits. Pressurized spent liquor is sent to the heat exchange zone where it absorbs heat from the coking zone effluent before coke separation, thereby absorbing also heat content contained in the coke. The coke is discharged to the kilning zone where it is dried by hot flue gases produced by burning previously dried coke in the steam producing zone. Sulfur dioxide containing warm, flue gas from the kilning zone is contacted in an absorbing zone with cool coker effluent to produce warm ammonium bisulfite solution which is passed to a wood digestion zone as well as cool flue gas substantially free of all air pollutants. Sulfur-containing gases produced by coking and wood digestion are burned in the steamproducing zone to manufacture sulfur dioxide for recycling. Use of a closed system reduces to a minimum odors in the digestion section of a pulp plant since all the odorous sulfur compounds are burned and the sulfur dioxide is recovered.

Abstract: IN THE FIRST STAGE OF A CONTINUOUS PROCESS OILY SLUDGES ARE MIXED WITH LIGHT HYDROCARBONS DIFFERING SUBSTANTIALLY IN SPECIFIC GRAVITY THEREFROM TO SEPARATE THE SLUDGES INTO AN OIL-HYDROCARBON PHASE A WATER-WAXY SOLIDS PHASE. THE OIL-HYDROCARBON PHASE IS HEATED TO A TEMPERATURE ABOVE THE CRITICAL TEMPERATURE OF THE LIGHY HYDROCARBONS TO REMOVE THE LIGHT HYDROCARBONS WHICH ARE THEN RECYCLED FOR FURTHER USE. THE WATER-WAXY SOLIDS PHASE IS TREATED TO OBTAIN WATER REDUCED CHEMICAL OXYGEN DEMAND WHICH CAN BE DISCHARGED IN RECEIVING BODIES OF WATER WITHOUT POLLUTING THE SAME. THE WAXY SOLIDS-WATER SLURRY WHICH REMAINS IS, IN THE SECOND STAGE OF THE PROCESS OF THIS INVENTION, DIRED AD THE RESULTING DRY WAXY SOLIDS ARE TREATED WITH A LIGHT ORAMITIC SOLVENT SUCH AS BENZENE, TO YIELD A SOLUTION OF WAX AND THE AROMATIC SOLVENT AND WAX-FREE SOLIDS. AFTER THE AROMATIC SOLVENT WAX SOULTION IS STRIPPED TO REMOVE THE AROMATIC SOLVENT, A VALUABLE WAX PRODUCT REMAINS. IN A FINAL STEP, THE WAX-FREE SOLIDS ARE HAETED TO REMOVE THE LAST TRACES OF THE AROMATIC SOLVENT THEREFROM YIELDING DRY, HYDROCARBON-FREE, SOLIDS WHICH ARE SUITABLE FOR A WIDE VARIETY OF USES, SUCH AS, FOR EXAMPLE, FOR LAND FILL.
