Abstract: A partial oxidation process for continuously producing synthesis gas, fuel gas or reducing gas in which process one fuel is replaced by a differing fuel without shutting down or depressurizing the gas generator. This multifuel process is not tied to one particular fuel and reacts slurries of solid carbonaceous fuel and/or liquid or gaseous hydrocarbonaceous fuels. Problems of fuel availability are reduced due to the wide selection of fuels that are suitable for the subject process. A two-section burner having a high turndown feature is employed that comprises a central conduit; a central bunch of tubes positioned in said central conduit; an outer conduit coaxial with said central conduit and forming an annular passage therewith; and an annular bunch of tubes positioned in said annular passage. The downstream ends of said central and/or annular bunches of tubes are respectively retracted upstream from the burner face a distance of about 0 to 12 i.e. 3 to 10 times the minimum diameter of the central exit orifie and the minimum width of the annular exit orifice. A control system is provided for switching the type of reactant fuel streams flowing through either one or both sections of the burner. The flow rates of the oxidant, fuel, and temperature moderator streams may also be varied in either one or both sections of the burner, thereby effecting a rapid turndown or turnup of the burner and a change in the production of the effluent gas.

Abstract: A burner and partial oxidation process for producing synthesis gas, fuel gas or reducing gas from slurries of solid carbonaceous fuel and/or liquid or gaseous hydrocarbon fuel. The burner has a high turndown feature and comprises a central conduit; a central bunch of parallel tubes that extend longitudinally through said central conduit; an outer conduit coaxial with said central conduit and forming an annular passage therewith; and an annular bunch of parallel tubes that extend longitudinally through said annular passage; and wherein the downstream ends of said central and annular bunches of parallel tubes are respectively retracted upstream from the burner face a distance of about 0 to 12 i.e. 3 to 10 times the minimum diameter of the central exit orifice and the minimum width of the annular exit orifice. Three ranges of flow through the burner may be obtained by using one or both bunches of tubes and their surrounding conduits. Throughput levels may be rapidly changed--up and down--without sacrificing stable operation. A control system is presented for varying the flow rates of the oxidant and fuel streams and/or for switching the reactant streams through one or both sections of the subject burner, thereby effecting a rapid turndown of the burner and in the production of the effluent gas.

Abstract: A partial oxidation process using a swirl burner for producing synthesis gas, fuel gas or reducing gas from slurries of solid carbonaceous fuel and/or liquid or gaseous hydrocarbon fuel. The swirl burner may have pre-mix and/or high turndown features. By means of the burner a first reactant stream is split into a plurality of swirling streams by being passed down through a central bundle of helical tubes. Simultaneously a second reactant stream is split into a plurality of swirling streams by being passed down through a plurality of related passages formed in the cylindrical space that surrounds said central bundle of helical tubes and/or the interstices between the helical tubes. When the two swirling reactant feed streams impinge, either upstream from the face of the burner in a pre-mix zone or downstream from the face of the burner, in the gas generator, they are intimately mixed together. The combustion efficiency of the burner is thereby improved. In another embodiment, the burner includes a coaxial annular bundle of helical tubes surrounding said first conduit and a plurality of related helical passages formed in the annular space occupied by said annular bundle of helical tubes. Flow through the burner may be turned up or down.

Abstract: Cryogenic liquefied natural gas (LNG) is used as a source of refrigeration and methane in the production of dry sulfur-free, methane-enriched synthesis gas or fuel gas. Raw syngas is indirectly and directly contacted with cryogenic liquefied natural gas (LNG) and cooled thereby below the dew point. Water is thereby condensed out and separated from the process gas stream. Further, the liquid LNG vaporizes and increases the methane content of the dewatered synthesis gas. Cold liquid absorbent solvent contacts the dry CH.sub.4 -enriched synthesis gas in an absorption column and absorbs the acid gases e.g. H.sub.2 S and COS and optionally H.sub.2 S+COS+CO.sub.2. In a preferred embodiment, the rich solvent absorbent is regenerated in a stripping column and the released acid gases are sent to a Claus unit for the production of elemental sulfur. In a second embodiment, the regenerated lean liquid absorbent solvent may be mixed with the dry, purified synthesis gas leaving from the top of the absorption tower. This mixture is then directly and optionally indirectly contacted with additional cryogenic liquid LNG. The CH.sub.4 content of the synthesis or fuel gas is thereby increased to a value in the range of about 10 to 80 mole %. By means of a decanter, dry, sulfur-free methane-enriched syngas product is separated from liquid absorbent solvent. The liquid absorbent solvent is then recycled to the absorption column.

Abstract: A raw synthesis gas feed stream, e.g., gaseous mixtures comprising H.sub.2 and CO and containing gaseous impurities including CO.sub.2, H.sub.2 S, COS, and mixtures thereof (acid gas) and CH.sub.4, optionally in admixture with a CO-rich gas stream produced subsequently in the process, is introduced into a water-gas shift reactor to produce H.sub.2 and CO.sub.2. Acid gases are then removed to produce a stream of purified synthesis gas by contacting the process gas stream with a first liquid solvent absorbent such as methanol, N-methyl-pyrrolidone, or dimethyl ether of polyethylene glycol. An H.sub.2 -rich gas stream may be obtained by removing CO from the purified synthesis gas stream. This may be done by physical absorption in a second liquid solvent absorbent comprising an aqueous solution of cuprous ammonium acetate. By regenerating the second liquid solvent, the aforesaid CO-rich stream may be produced. The first liquid solvent absorbent may be desorbed of said acid gas and regenerated for reuse by such techniques as flashing plus reboiling or stripping. Advantageously, the gas used for stripping the first liquid solvent absorbent may be a portion of the synthesis gas feed either before or after removal of said acid-gas, or a portion of said H.sub.2 -rich product gas. The CO.sub.2 -rich gas optionally in admixture with stripping gas which is produced during the regeneration of said first liquid solvent absorbent may be injected into a subterranean oil reservoir to effect secondary or tertiary recovery of oil. Optionally, H.sub.2 S may be in admixture with said CO.sub.2 -rich gas mixture.

Abstract: The hot raw synthesis gas stream leaving the reaction zone of a free flow partial oxidation gas generator at a temperature in the range of about 1800.degree. to 3000.degree. F. is passed through a first gas diversion and residue separation chamber where the velocity of the gas stream is reduced and its direction is diverted into a side transfer line. Solid material and molten slag separate by gravity from the gas stream. The hot gas stream is then introduced into second gas diversion and residue separation zone comprising at least one thermally insulated gas-solids impingement separation means were additional solid matter and slag is separated. For example, from about 2 to 8 thermally insulated gas-solids impingement separators may be employed which are connected in parallel and/or series. In one embodiment, about 0 to 20 vol. % of the hot gas stream may be passed through bottom outlets in said first and second gas diversion zones in order to prevent bridging. The hot gas stream from the second gas diversion zone is passed upwardly through a radiant cooling zone where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900.degree. to 1800.degree. F.
