    摘要: Trim control of a partial oxidation gas generator for the production of synthesis gas, reducing gas, or fuel gas is effected by two improved control schemes which are automatically operated separately or in sequence. The control systems include sensors sensing the flow rate of the feedstreams and analyzers which provide signals corresponding to the wt. % carbon in the effluent gas quench cooling and scrubbing water for use in controlling the particulate carbon in the effluent gas stream, and/or signals corresponding to the mole fractions of CO.sub.2, CH.sub.4, CO and H.sub.2 (dry basis) in the cooled and cleaned effluent gas stream for use in controlling the temperature in the reaction zone. The signals from the sensors and analyzers are provided to the system control unit which computes values that represent the relative difference between the actual and desired carbon-make and/or the actual temperature in the reaction zone, and the relative difference between the actual and desired temperature in the reaction zone. The actual temperature is determined as a function of the methane equilibrium constant. These values are automatically compared with set point values and when adjustments are necessary, signals from the system control unit are provided to a flow rate regulating means which adjusts the flow rate of the free-oxygen containing gas by a small determined amount for control of the particulate carbon and/or to a flow rate regulating means which adjusts the flow rate of the temperature moderator by a small determined amount for control of the temperature in the reaction zone.

    摘要: A nitrogen-rich inert gas mixture is produced by the partial oxidation of a hydrocarbonaceous feed containing substantially no metals nor noncombustible materials with air in a free-flow, unpacked, refractory-lined gas generator at a temperature in the range of about 1300.degree. to 3000.degree. F. and a pressure in the range of about 1 to 250 atmospheres. The product gas will comprise a mixture of nitrogen, argon and carbon dioxide and may contain small amounts of hydrogen and carbon monoxide, depending on the O/C atomic ratio selected. The atomic ratio of free oxygen in said air to carbon in said hydrocarbonaceous fuel is in the range of about 1.7 to stoichiometric, or slightly less than stoichiometric. By operating at this level of O/C atomic ratio, the H.sub.2 + CO content of the product gas may be minimized or deleted, substantially all of the particulate carbon may be oxidized, substantially no NO.sub.x is produced, and the product gas contains substantially no free oxygen. Further, the sensible heat recovered from the product gas may be used to manufacture by-product high pressure steam for export. The nitrogen-rich product gas may be used for oil formation flooding, or as a pressurizing or blanketing gas. Costly gas compressors may be avoided since the product gas may be produced at or above use pressure.

    摘要: The hot process gas stream from the partial oxidation of sulfur-containing heavy liquid hydrocarbonaceous fuel and/or sulfur-containing solid carbonaceous fuel comprising gaseous mixtures of H.sub.2 +CO, sulfur-containing gases, entrained particulate carbon, and molten slag is passed through the unobstructed central passage of a radiant cooler where the temperature is reduced to a temperature in the range of about 1800.degree. F. to 1200.degree. F. From about 0 to 95 wt. % of the molten slag and/or entrained material may be removed from the hot process gas stream prior to the radiant cooler with substantially no reduction in temperature of the process gas stream. In the radiant cooler, after substantially all of the molten slag has solidified, the sulfur-containing gases are contacted with a calcium-containing material to produce calcium sulfide. A partially cooled stream of synthesis gas, reducing gas, or fuel gas containing entrained calcium sulfide particulate matter, particulate carbon, and solidified slag leaves the radiant cooler containing a greatly reduced amount of sulfur-containing gases.

    摘要: This is a continuous process for producing hydrogen-rich gas. Successive beds of water-gas shift conversion catalysts of differing properties are employed in a shift converter to achieve an economical balance between catalyst activity and catalyst life. For example, a comparatively small fixed bed of highly active low temperature water-gas shift conversion catalyst may be loaded on top of a fixed bed of rugged low cost moderately active high temperature water-gas shift catalyst. A CO-rich gas and H.sub.2 O are introduced into the bed of low temperature shift catalyst where reaction takes place. The partially reacted gas stream leaves the bed of low temperature shift catalyst and is introduced into the bed of high temperature catalyst at a suitable temperature for triggering off therein the water gas shift reaction without the additon of heat from an external source. By this means it may be possible to produce hydrogen-rich gas with high conversions of CO to CO.sub.2, and to increase catalyst life at a moderate cost. It may also be possible to eliminate a feed heater or feed-product heat exchanger.

    摘要: A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, ammonia, alkali metal compounds, halides and sulfur-containing gas for use as synthesis gas, reducing gas, or fuel gas. A hydrocarbonaceous fuel comprising a solid carbonaceous fuel with or without liquid hydrocarbonaceous fuel or gaseous hydrocarbon fuel, wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H.sub.2, CO, CO.sub.2, H.sub.2 O, CH.sub.4, NH.sub.3, HCl, HF, H.sub.2 S, COS, N.sub.2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is split into two streams which are separately deslagged, cleaned and recombined. Ammonia in the gas mixture is catalytically disproportionated into N.sub.2 and H.sub.2. The ammonia-free gas stream is then cooled and halides in the gas stream are reacted with a supplementary alkali metal compound to remove HCl and HF. Alkali metal halides, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000.degree. F.

    摘要: Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell. A reaction chamber within the shell receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and is provided with a thermal barrier along its surface that is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.
