Abstract: A WATER TREATMENT PROCESS FOR BREAKNG EMULSIONS SUCH AS ALGAE-OIL-WATER EMULSIONS INTO GAS, OIL, WATER AND COKE INCLUDES THE STEPS OF COKING THE EMULSIONS UNDER AUTOGENOUS PRESSURE AT 450 TO 700*F. FOR 0.5 MINUTE TO 120 MINUTES, COOLING TO FORM A SEPARABLE, FOUR PHASE SYSTEM COMPRISING GASES, OIL, WATER AND COKE; VENTING OFF THE GASES; REMOVING THE OIL TO THEREBY OBTAIN A WATER-COKE SLURRY, FILTERING OFF THE COKE AND COLLECTING AN AQUEOUS PHASE. THE AQUEUS PHASE CAN BE REDUCED IN COD BY TREATING WITH AIR AT ELVATED TEMPERATURE PRIOR TO FINAL DISPOSAL. THE OIL IS SUITABLE FOR REVYCLING TO A CRUDE STILL. THE PROCESS CAN BE CARRIED OUT EITHER BAECHWISE OR ON A CONTINUOUS BASIS AND IS PARTICULARLY USEFUL FOR BREAKING ALGAE-OIL EMULSIONS OCCURING IN API SEPARATORS.
