    Abstract: A method is provided for turning down from design conditions or below the output of raw product gas from a free-flow partial oxidation gas generator, or when operating below design conditions the output of raw product gas from the gas generator may be turned up while maintaining substantially constant the efficiency of the gas generation, or conversion of the fuel to gas, and the quality of the gas produced. The flow rates of the feedstreams to the burner are adjusted down or up a predetermined amount for each of the feedstreams to the burner to obtain a specified output of raw product gas while maintaining substantially constant in the reaction zone the levels of O/C atomic ratio and the H.sub.2 O/fuel weight ratio. Further, a pressure adjustment in the system is made which produces a corresponding adjustment to the pressure in the gas generator. The adjusted pressure is a direct function of the adjusted flow rate for the adjusted fuel or oxidant feedstream.

    Abstract: An improved continuous partial oxidation process 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.degree. to 850.degree. 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.

    Abstract: An improved continuous partial oxidation process for producing clean synthesis or fuel gas and by-product steam from a hydrocarbonaceous fuel feed is disclosed wherein hot gases from the process are simultaneously cooled and cleaned by direct contact with hydrocarbon oil. Thus, the 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 immersion fluid. 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 cooled to a temperature in the range of about 300.degree. to 850.degree. F. but above the dew point of the water in the process gas stream in an external heat exchanger, such as a steam generator. High pressure by-product steam may be produced thereby. A portion of the cooled immersion fluid, optionally in admixture with a hydrocarbonaceous scrubbing fluid of a similar composition obtained subsequently in the process may be recycled to the immersion vessel and optionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed.

Thus, the 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 immersion fluid. For example, the immersion fluid may be a dispserion of liquid hydrocarbonaceous fuel such as petroleum oil and particulate carbon which is contained in a separate immersion vessel. A portion of the immersion fluid is continuously removed from the immersion vessel and is cooled in an external cooler to a temperature in the range of about 300 to 850.degree. F but above the dew point of the water in the process gas stream. Portions of the cooled immersion fluid optionally in admixture with scrubbing fluid obtained subsequently in the process are recycled to the immersion vessel, and optionally to the gas generator as at least a portion of the hydrocarbonaceous fuel feed. In another emnbodiment, 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 effluent gas stream leaving said immersion zone may be subjected to additional cleaning by being scrubbed with said scrubbing fluid comprising make-up hydrocarbonaceous fuel and particulate carbon in a separate scrubbing zone. 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.10 hydrocarbons.
