摘要： A highly efficient partial oxidation process with the production of power comprising the steps of producing fuel gas by the partial oxidation of hydrocarbonaceous fuel, cooling said fuel gas at high pressure by quenching in water to produce quenched fuel gas and by indirect heat exchange with BFW to maximize the production of IP and MP steam, cleaning said fuel gas, preheating scrubbing water comprising process condensate and make-up water by direct contact and direct heat exchange with clean fuel gas and using said preheated scrubbing water in the cleaning of said fuel gas, reducing the pressure of said cooled fuel gas stream prior to heating water for fuel gas saturation, cooling the process fuel gas stream in stages and condensing water for use as said scrubbing water, purifying the process fuel gas and saturating it with water, and burning said purified and saturated fuel gas in the combustor of a power-producing gas turbine along with saturated nitrogen to produce exhaust gas with a reduced NO.sub.x. In one embodiment, the hot exhaust gas from the gas turbine is passed through a HRSG to superheat the process steam. The superheated process steam is then used as part of the working fluid in an expansion turbine for the production of power. Steam condensate may be converted into high pressure (HP) steam and superheated in the HRSG. The power generation steam cycle is optimized to assist in maximizing the process steam which can be used most efficiently in the cycle.

摘要： A process is provided for the partial oxidation of a high metals or ash containing liquid hydrocarbonaceous fuel or a slurry of solid carbonaceous fuel to simultaneously produce saturated and unsaturated raw streams of synthesis gas, reducing gas, or fuel gas. Two continuous partial oxidation reactions in two separate reaction zones go on simultaneously. The fuel feed to the first partial oxidation zone is said fresh high metals or ash containing fuel. The raw product gas stream from the first partial oxidation zone is split into first and second split gas streams. The first split gas stream may be cooled in a radiant and/or convection type gas cooler without fouling heat exchange surfaces. The fuel feed to the second partial oxidation zone is a pumpable slurry which is prepared from the entrained matter that is separated from said gas streams during quench cooling and cleaning operations and which contains a comparatively high amount of metals and/or ash. The partial oxidation reaction takes place in the second partial oxidation zone in a reducing atmosphere that includes the second split raw product gas stream from the first partial oxidation zone. By the subject process, there is a reduction in the unconverted carbon produced without any significant loss in efficiency. Further, the life of the cooler for the raw product gas stream is increased.

摘要： The raw syngas generated in a partial oxidation gasifier also includes carbon soot which is removed and recovered from the syngas by scrubbing with water. The scrubbing water contains one or more high temperature surfactants which allow greater soot concentrations in the water-scrubbing quench zone of the gasifier. The carbon soot is separated from the scrubbing water with the aid of a scrubbing oil. The separation of the carbon soot from the scrubbing water is enhanced with the aid of one or more surfactants that render the soot particles hydrophobic and oleophilic. The recovered carbon soot is ultimately recycled to the gasifier to recover the energy value of the carbon during the partial oxidation reaction. The overall energy efficiency of the gasification process can be increased by removing all or a significant portion of the water from the soot mixture before recycling the soot. Separating the soot from the water allows for independent regulation of the soot and water recycle streams, depending on the reaction conditions in the gasifier.

摘要： The present invention relates to an integrated process and apparatus for supplying at least a portion of, or substantially all, or all of the reducing gas feedstock to a reduction reactor, such as a reactor for the direct reduction of iron, wherein the reducing gas contacts a feed material at a mean operating gas pressure and effects reduction of the feed material to provide a reduced product. The integrated process includes the production of a hydrogen-rich gas by the partial oxidation of a hydrocarbonaceous feedstock to produce a hydrogen-rich gas, which can also be referred to as a synthesis gas or syngas. The synthesis gas is at a pressure substantially greater than the mean operating gas pressure in the reduction reactor. The synthesis gas is expanded to lower its pressure to substantially the mean operating gas pressure in the DRI reduction reactor to thereby form the reducing gas feedstock at the pressure conditions used for the DRI reaction. The lower pressure reducing gas mixture generated by the expansion is introduced into the DRI reactor as part or all of the reducing gas requirement for the direct reduction of iron.

摘要： A gas cooler and process are provided for the efficient extraction of heat from a hot raw gas stream containing entrained matter from the partial oxidation of a hydrocarbonaceous or carbonaceous fuel, and the simultaneous production of a separate stream of superheated steam. The gas cooler comprises a closed vertical pressure vessel with an upper central outlet through which the superheated steam is removed. A refractory lined hot gas inlet chamber is attached to the bottom of the pressure vessel. A plurality of bundles of helical tubes through which the hot gas flows are spaced in the vessel. The hot gas enters at the bottom of the vessel and the cooled gas leaves at the bottom of the helical coil. A portion of the vessel is filled with boiler feed water so that the bundles of helical tubes are partially submerged. Concurrent and countercurrent indirect heat exchange between boiler feed water and the gas stream takes place in the evaporator section to produce saturated steam. Concurrent and countercurrent indirect heat exchange between the saturated steam and the partially cooled gas stream then takes place in the superheater section to produce superheated steam. Advantageously, the gas cooler may be easily turned up or down with load by opening or closing off at least one of the helical tubes. This may be done by valving located downstream from the gas cooler at the cold end of the gas path.
