PRODUCTION OF CLEAN SYNTHESIS OR FUEL GAS (D#74,665-FB) ABSTRACT OF THE DISCLOSURE An improved continuous partial oxidation process for producing clean synthesis or fuel gas from a hydrocar- bonaceous fuel feed is disclosed wherein the hot effluent gas stream from the reaction zone of the gas generator is cooled and cleaned by discharging the gas stream directly into a relatively large body of hot liquid hydrocarbon im- mersion fluid. A portion of the immersion fluid is contin- uously removed from the immersion vessel and is cooled in an external cooler to a temperature in the range of about 300 to 850°F. but above the due point of the water in the process gas stream. For example, the external cooler may be a waste heat boiler for the production of high pressure steam. Portions of the cooled immersion fluid optionally in admixture with scrubbing fluid obtained subsequently in the process are recycled to the immersion vessel, and op- tionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed. The effluent gas stream leav- ing said immersion zone may be subjected to additional cleaning by being scrubbed with said scrubbing fluid com- prising make-up hydrocarbonaceous fuel and particulate carbon in a separate scrubbing zone. Additional cleaning of the effluent gas stream may be effected by scrubbing with noxious by-product water.
