An improved continuous partial oxidation process is claimed for producing clean synthesis or fuel gas from a hydrocarbonaceous fuel feed is disclosed wherein the effluent gas stream from the reaction zone of the gas generator is simultaneously cooled and cleaned by first discharging the gas stream directly into a relatively large body of hot liquid hydrocarbon immersion fluid contained in an immersion vessel, and second by scrubbing with by-product water obtained subsequently in the process in a nozzle scrubber. The process gas stream is optionally cooled and passed into a gas-liquid separator where any condensed by-product noxious water and any C/sub 5/--C/sub 10/ liquid hydrocarbons are separated from each other and from the clean product gas stream. By-product noxious water is disposed of without polluting the environment by recycling a portion of it to the gas generator as the temperature moderator. For example, the immersion fluid may be a dispersion of liquid hydrocarbonaceous fuel such as petroleum oil and particulate carbon which is contained in a separate immersion vessel. A portion of the hot immersion fluid is continuously removed from the immersion vessel and is cooled in an external gas cooler to a temperature in the range of about 300 to 850/sup 0/F but above the dew point of the water in the process gas stream. Portions of the cooled immersion fluid are recycled to the immersion vessel, and optionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed. In another embodiment, a portion of the immersion fluid removed from the immersion vessel may be introduced into the gas generator as at least a portion of the feed without first being passed through a cooler. The clean product gas comprises H/sub 2/, CO, CO/sub 2/, H/sub 2/O and, optionally at least one material from the group H/sub 2/S, COS, N/sub 2/, A, and C/sub 1/--C/sub 4/ hydrocarbons. 11 claims, 1 figure.
