摘要:
This is an improved continuous partial oxidation process for producing synthesis gas or fuel gas from a solid carbonaceous fuel. Liquid CO.sub.2 and a ground solid carbonaceous fuel such as coal are mixed together to produce a pumpable slurry feed. The CO.sub.2 serves as a carrier for the carbonaceous fuel and as a temperature moderator, and is preferably obtained by purifying the product gas.

摘要:
A high turndown de-slagging burner is provided for simultaneously introducing one or two mixed pairs of reactant feedstreams into a free-flow noncatalytic partial oxidation gas generator for the production of synthesis gas, fuel gas, or reducing gas by way of the central and/or annular sections of the burner, respectively. Each pair of feedstreams comprises a stream of free-oxygen containing gas with or without a temperature moderator and a pumpable liquid slurry stream of solid carbonaceous fuel, such as a coal-water slurry. Other hydrocarbonaceous fuels may be employed. The burner comprises four coaxial concentric conduits that are radially spaced to provide coaxial concentric annular passages. All of the conduits and annular passages are closed at the upstream ends and open at the downstream ends. Each pair of feedstreams is separately mixed together in a central or annular pre-mix chamber located upstream from the face of the burner. A water-cooled flat face-plate is provided with separate passages for discharging air or soot-blowing or de-slagging media at the face of the burner.

摘要:
This is an improved continuous partial oxidation process for producing synthesis gas or fuel gas from gaseous CO.sub.2 -solid carbonaceous fuel feeds. A solid carbonaceous fuel such as finely ground coal from a pressurized lock hopper is passed directly into a high pressure high velocity CO.sub.2 -rich gas stream which carries the particles of coal into a free-flow noncatalytic gas generator where by the partial oxidation reaction with a free-oxygen containing gas, preferably in the absence of supplemental H.sub.2 O other than that normally present in the reactants, gaseous mixtures principally comprising H.sub.2, CO, CO.sub.2, and H.sub.2 O are produced. A CO.sub.2 -rich gas stream is recovered downstream in the process and recycled to the pressurized feed system. The CO.sub.2 -rich stream serves as a carrier for the carbonaceous fuel and as a reactant in the reaction zone.

In the partial oxidation of a sulfur- and metal-containing carbonaceous charge fuel to produce a sulfur-containing synthesis gas and metal-containing molten slag, an integrated method of charge fuel pretreatment and Claus unit tail gas sulfur removal is provided. The process of the instant invention is advantageous over other partial oxidation processes in that: (i) a fluid, molten slag which flows easily is produced, thereby improving reactor performance; and (ii) the overall removal of sulfur compounds from the synthesis gas is made simpler, more efficient, and less costly, as the need for a conventional Claus unit tail gas sulfur removal process is eliminated.

摘要:
The subject process pertains to the secondary recovery of oil by the steam stimulation of an underground oil reservoir. As an added benefit, mechanical power and/or electrical energy may be simultaneously produced. In the subject process, raw fuel gas is first produced by the partial oxidation in a free-flow gas generator of a hydrocarbonaceous feed, such as preferably a portion of the oil recovered. The raw fuel gas is cleaned, purified, and burned in a gas turbine which drives a compressor or electric generator. The sensible heat in the raw fuel gas leaving the gas generator and in the flue gas discharged from the gas turbine is recovered by the production of high quality steam. This steam is injected into subterranean formations and reservoirs to accelerate production and to provide additional oil recovery.
