Claim 1
Independent Claim
119 words
A METHOD FOR RECOVERING CARBONACEOUS SOLID FROM A GAS STREAM RESULTING FROM REACTION OF CARBONACEOUS FUEL WITH OXYGEN IN A REACTION ZONE TO PRODUCE A PRODUCT GAS STREAM COMPRISING CARBON MONOXIDE, HYDROGEN AND ENTRAINED CARBONACEOUS SOLID, WHICH COMPRISES CONTACTING SAID PRODUCT GAS STREAM WITH WATER IN A GAS SCRUBBING ZONE EFFECTING REMOVAL OF CARBONACEOUS SOLID FROM SAID GAS STREAM FORMING A DISPERSION OF SOLID IN WATER, CONTACTING SAID DISPERSION WITH A VOLATILE LIQUID HYDROCARBON IN A MIXING ZONE EFFECTING RESOLUTION OF SAID DISPERSION INTO CLARIFIED WATER AND FLOATING HYDROCARBON-WET SOLID, VAPORIZING HYDROCARBON FROM SAID HYDROCARBON-WET SOLID IN THE PRESENCE OF SAID WATER LEAVING UNIDISPERSED SOLID FLOATING IN SAID CLARIFIED WATER, AND SEPARATELY WITHDRAWING SAID UNDISPERSED SOLID AND CLARIFIED WATER.
