International Classification:

C10J 346

US Classification:

48197R

Abstract:

A partial oxidation process and control system for continuously producing synthesis gas, fuel gas or reducing gas in which one process fuel is replaced by a different 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. Suitable burners for introducing the feedstreams into the gas generator comprise a central conduit means radially spaced from a concentric coaxial outer conduit having a downstream exit nozzle, and providing a coaxial annular passage means therebetween. The central conduit means may be retracted upstream from the burner face a distance of about 0 to 12 and preferably 3 to 10 times the minimum diameter of the central exit orifice. A premix zone is preferably provided comprising one or more, say 2 to 5 coaxial chambers in series where substantial mixing of the reactant streams and optionally volatilization of the slurry medium takes place. A control system is provided for switching the type of reactant fuel stream flowing through either the central conduit means or the annular passage means of the burner and adjusting the flow rates of the reactant stream of free-oxygen containing gas.

Abstract:

A process for recovering particulate carbon from the effluent gas stream from a partial oxidation synthesis-gas generator by scrubbing the effluent gas with water in a scrubbing zone to form a carbon-water dispersion, by mixing said dispersion with a liquid organic extractant comprising a mixture of the liquid organic by-products from the oxo or oxyl process so as to produce a clarified water layer and a carbon-extractant dispersion, by separating and recycling said clarified water to said scrubbing zone, and by introducing part or all of said carbon-extractant dispersion to said gas generator as at least a portion of the generator feedstock.

International Classification:

C10J 348

US Classification:

48 61

Abstract:

Heavy hydrocarbon fuel containing high metal concentrations and all of the soot which is rich in metals that is produced in the system, are feedstocks in a partial oxidation process for the simultaneous continuous production of two streams of cleaned, raw synthesis gas having high and low H. sub. 2 O/dry gas mole ratios, respectively. In the process, all of the stream of hot, raw synthesis gas containing entrained particulate carbon and ash that is produced in a first gas generator is quench cooled and scrubbed with water in a quench tank. Simultaneously, split streams of hot raw synthesis gas containing entrained particulate carbon and ash are produced in a second gas generator. One split gas stream is quench cooled and scrubbed with water in a quench tank while the other split gas stream is simultaneously cooled in a convection-type gas cooler and then scrubbed with water. All of the soot recovered from the quench cooling and scrubbing waters in the process is recycled to the first gas generator as a portion of the reactant fuel feed. Fouling and plugging of the tubes of a convection-type gas cooler associated with the second gas generator is prevented.

International Classification:

US Classification:

48 61

Abstract:

A control system for a partial oxidation process for continuously producing synthesis gas, fuel gas or reducing gas in which process one fuel is replaced by a different 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 orifice and the minimum width of the annular exit orifice.

Abstract:

A continuous process for simultaneously producing a stream of cleaned purified synthesis gas having a mole ratio H. sub. 2 /CO in the range of about 2 to 12, and a separate stream of CO-rich gas. In one embodiment of the process, cleaned and purified methanol synthesis gas and substantially pur carbon monoxide are produced. Methanol may be synthesized and optionally catalytically reacted with the substantially pure carbon monoxide to produce acetic acid. In the subject process, the effluent gas stream directly from a free-flow unpacked noncatalytic partial-oxidation synthesis gas generator is split into two streams which are simultaneously processed in two separate trains. In the first train, one of the split streams is cooled by indirect heat exchange in a gas cooler and then further processed to produce a stream of cleaned and purified synthesis gas, a H. sub. 2 -rich gas stream, and the product stream of CO-rich gas and preferably substantially pure CO. Simultaneously, the second split stream in the second train is cooled by direct quenching in water in a quench drum, cleaned, subjected to catalytic water-gas-shift reaction, and purified to produce a second H. sub.

US Classification:

48197R

Abstract:

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.

Abstract:

A burner 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.
