摘要： An improvement in a chemical recovery process in which a hot liquid smelt is introduced into a dissolving tank containing a pool of green liquor. The improvement comprises preventing smelt explosions in the dissolving tank by maintaining a first selected superatmospheric pressure in the tank during normal operation of the furnace; sensing the pressure in the tank; and further impinging a high velocity stream of steam upon the stream of smelt whenever the pressure in the tank decreases below a second selected superatmospheric pressure which is lower than said first pressure.

摘要： A process for recovering the energy and chemical content of an aqueous black liquor utilizing a reactor containing a drying zone located above a gasification zone. The reactor contains a bed of porous solid carbonaceous material in the gasification zone. Heat losses are restricted, preferably from both zones, by the provision of a layer of insulating material about the reactor. An oxygen-containing gas is introduced into the gasification zone in an amount less than about 60% of that required for complete combustion of the black liquor such that there is produced partial combustion and gasification reactions sufficient to maintain the temperature at an upper surface of the bed in the range of from about 870.degree. to 1200.degree. C. and to form a hot combustible gas which rises from the gasification zone. A concentrated black liquor containing alkali metal, oxysulfur compounds is introduced into the drying zone and the water contained therein evaporated by contact with the hot gases rising from the gasification zone. In the drying zone there is produced a reduced temperature product gas and dry black liquor solids which fall onto the surface of the bed in the gasification zone. The dried black liquor solids are converted into the hot combustible gas which rises from the gasification zone and alkali metal salts which melt and permeate through the bed. The product gases are withdrawn from an upper portion of the drying zone, and a melt in which the sulfur content is about 80% in the form of alkali metal sulfide is withdrawn from a lower portion of the gasification zone.

摘要： A process for removing sulfur oxides from a hot gas by sequential absorption of the sulfur oxides in two zones. In each zone the hot gas is contacted with an aqueous scrubbing medium which may be a solution or slurry containing an absorbent for the sulfur oxides. The absorbent is selected from the group consisting of alkali metal carbonates, bicarbonates and mixtures thereof. The preferred absorbent is sodium carbonate. The aqueous solution is introduced into the first zone in an amount to produce (1) a dry powder reaction product containing alkali metal sulfites, and sulfates, substantially free of unreacted absorbent and (2) a substantially water-unsaturated gaseous reaction product of reduced sulfur oxide content. The gaseous reaction product of reduced sulfur oxide content is transferred into the second zone where it is contacted with a sufficient amount of an aqueous solution of absorbent to provide (1) a gaseous reaction product substantially free of sulfur oxide and (2) an aqueous solution containing alkali metal sulfites, sulfates and unreacted absorbent, which solution is used as at least a part of the aqueous solution fed into the first zone.

摘要： A concentrated aqueous black liquor containing carbonaceous material and alkali metal sulfur compounds is treated in a gasifier vessel containing a relatively shallow molten salt pool at its bottom to form a combustible gas and a sulfide-rich melt. The gasifier vessel, which is preferably pressurized, has a black liquor drying zone at its upper part, a black liquor solids gasification zone located below the drying zone, and a molten salt sulfur reduction zone which comprises the molten salt pool. A first portion of an oxygen-containing gas is introduced into the gas space in the gasification zone immediatley above the molten salt pool. The remainder of the oxygen-containing gas is introduced into the molten salt pool in an amount sufficient to cause gasification of carbonaceous material entering the pool from the gasification zone but not sufficient to create oxidizing conditions in the pool. The total amount of the oxygen-containing gas introduced both above the pool and into the pool constitutes between 25 and 55% of the amount required for complete combustion of the black liquor feed. A combustible gas is withdrawn from an upper portion of the drying zone, and a melt in which the sulfur content is predominantly in the form of alkali metal sulfide is withdrawn from the molten salt sulfur reduction zone.

摘要： The present invention provides a process for upgrading a hydrocarbon material in the presence of a molten salt in a manner which reduces the requirements for expensive ceramic materials to withstand the corrosive nature of the salt. A molten salt containing carbon is introduced into a heat generation zone which is located in a lower portion of an upwardly extending elongated reactor. Oxygen is introduced into the heat generation zone in an amount sufficient to react with substantially all of the carbon and to heat the molten salt to a desired temperature. The heated molten salt together with the gaseous reaction products of the carbon-oxygen reaction flows upwardly through the reactor to a hydrocarbon material reaction zone which is located within the reactor and above the heat generation zone. The hydrocarbon material to be treated is introduced into the reaction zone and into the molten salt where it produces gaseous reaction products and unreacted carbon entrained in the flowing molten salt. Thereafter the molten salt is introduced into a quench zone which is located above the reaction zone and into which there is introduced a quenching medium to reduce the temperature of the molten salt to a temperature below that at which expensive materials of construction, such as ceramics, are required.

摘要： A method of and apparatus for removing particulate contaminants from a gaseous stream. Broadly, the apparatus comprises a housing containing a substantially vertical granular material retention member having upstream and downstream faces, a substantially vertical microporous gas filter element, said member and element being spaced apart to provide a zone for the passage of granular material therethrough. The housing further comprises a gas inlet means, a gas outlet means and means for moving a body of granular material through said zone. In operation, a gaseous stream containing particulate contaminants passes through the gas inlet means and upstream face of the granular material retention member, passing through said member, said body of granular material, the microporous gas filter element and then out the gas outlet means. The particulates carried in the gaseous stream pass into the granular material and are retained in the body of granular material and upon the upstream face of the gas filter element. The body of granular material is moved through the zone and across the upstream face of the gas filter element to scour the upstream face and remove the collected particulates, which are carried out of the housing, such that a substantially uniform pressure drop across the apparatus is maintainable during its operation.
