    摘要: Dispersions comprising water and particulate solids i.e. carbon and ash are produced in at least one gas cooling or scrubbing zone by quench cooling or scrubbing, or both the raw gas stream from a partial oxidation gas generator with water. Advantageously, the water may be reclaimed by the subject process. In one embodiment, the carbon-water dispersion containing any ash is mixed with a liquid organic extractant and a liquid aqueous emulsion. The emulsion breaks up, and in a decanting operation a carbon-extractant-water dispersion containing gaseous impurities separates out and floats on a dilute bottoms water layer containing gaseous impurities and some solids. The carbon-extractant-water dispersion is mixed with a heavy liquid hydrocarbon and introduced into a distillation column. The overhead from the distillation column is cooled and separated in a separation vessel into an upper layer of liquid organic extractant, an intermediate layer of aqueous emulsion, a bottom layer of water, and an overhead stream of uncondensed gaseous impurities if any. The liquid aqueous emulsion and the liquid extractant are recycled to the decanting operation. The water layer from the separation vessel and the bottoms water from the decanting operation are separately introduced into a flash column where the water is reclaimed. The flash column includes at least one stripping plate and two chambers at the bottom separated by a weir. The overhead from the flash column is cooled below the dew point and is introduced into said separation vessel. In another scheme, the emulsion is mixed with the bottoms water from the decanting operation and fed to a flash column for reclaiming water. Alternately, the aqueous emulsion is broken-up into water and liquid hydrocarbon by heating.

    摘要: This is a process and apparatus for continuously separating a liquid mixture comprising particulate carbon produced by the partial oxidation of a hydrocarbonaceous fuel, water, and liquid organic extractant into two separate immiscible streams i.e. a stream of particulate carbon-liquid organic extractant dispersion and a separate stream of clarified water. The subject apparatus may be referred to as a carbon decanter and comprises a closed pressure vessel whose horizontal cross-section is circular. Thus, the decanter may be shaped like a vertical cylinder or may be spherical shaped with discharge ports in the top and bottom. The liquid mixture of particulate carbon, water, and liquid organic extractant is charged into said vessel by way of a conduit which terminates at a position within the vessel along the vertical axis about 1/4 to 3/4 of the vessel height and below the interface level which is formed in said vessel when the two immiscible liquids separate by gravity with the water forming a pool at the bottom of the vessel. Alternately, the decanter may be charged through two concentric pipes. A horizontal radial nozzle terminates each pipe. By this means the aforesaid mixture of immiscible liquids may be introduced into the decanter by way of an annular passage located between said pipes. Further, simultaneously a separate stream of liquid organic extractant may be passed through the center pipe and discharged adjacent to the interface level. The dispersion of particulate carbon-liquid organic extractant separates from the water and may be removed by way of the top port as a continuous stream. Simultaneously a continuous stream of clarified water may be removed from the bottom port.

    摘要: 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.
