Abstract:
Disclosed is a process for disposing of aqueous sewage and for producing fresh water by coking the sewage in the liquid phase to form gases, coke and an effluent which is extracted with a hot liquid hydrogen to form a hydrocarbon-water solution and a concentrated brine. Cooling of the hydrocarbon-water solution results in the formation of distinct hydrocarbon and water phases which can be separated by gravity.
Abstract:
A combination process for treating both municipal refuse and sewage includes the steps of shredding the solid refuse and mixing the shredded material thus obtained with a recycle stream of water resulting from a subsequent coking step to form a slurry; removing noncombustible materials from this slurry; mixing the slurry with sewage sludge and coking the resulting mixture under a pressure sufficient to prevent the vaporization of water, thereby producing grease, clean water and clean coke.
Abstract:
Separation and recovery of oil from oil slicks on the surface of water by continuously and selectively picking up the surface oil in a relatively thick blanket of a bulk fabric composed of highly oleophilic fibers expressing the oil from the blanket and leaving the fibers in an open condition highly receptive to additional oil.
Abstract:
CLEANING UP MARINE OIL SPILLS BY FREEZING THE SURFACE LAYER OF OIL, PREFERABLY WITH PARTICLESS OF DRY ICE OR THE LIKE, TO ENABLE THE LAYER TO BE SCREENED OFF THE SURFACE AS A CAKE.
Abstract:
PROCESS FOR TREATMENT OF WASTE LIQUORS FROM PULP AND PAPER MILLS WHEREIN WASTE LIQUOR IS HEATED UDER TURBULENT FLOW CONDITIONS IN A TUBULAR HEATER TO A TEMPERATURE ABOVE ABOUT 450*F. UNDER PRESSURE SUFFICIENT TO PREVENT VAPORIZATION OF WATER AND FORM A WATER INSOLUBLE SOLID PRODUCT, OR COKE, WHICH IS SEPARATED FROM TREATED AQUEOUS LIQUID EFFLUENT OF LOW COD SUITABLE FOR REUSE IN THE PROCESS OR FOR DISPOSAL IN LAKES AND STREAMS WITHOUT SIGNIFICANT WATER POLLUTION.
Abstract:
A PROCESS FOR TREATING AQUEOUS ORGANIC WASTE LIQUOR INCLUDING THE STEPS OF COKING THE WASTE LIQUOR, IN THE ABSENCE OF FREE OXYGEN, THEREBY FORMING A COKE-CONTAINING AQUEOUS SLURRY, STEAM, GASES, AND AN EFFLUENT, SEPARATING AQUEOUS LIQUID FROM SAID SLURRY AND CONBINING SAID AQUEOUS LIQUID WITH SAID EFFLUENT, AND AIR-OXIDIZING THE THUS COMBINED LIQUIDS TO YIELD A HOT EFFLUENT HAVING A REDUCED CHEMICAL OXYGEN DEMAND.
