摘要： A chlorine dioxide generating process is described wherein chlorine formed with the chlorine dioxide is used to form acid reactant for the chlorine dioxide generating process by reaction with sulphur dioxide and water. The substantial evaporation of the water which would otherwise result from the exothermic nature of the reaction is prevented by controlling the temperature of the water during the reaction. In one embodiment, the temperature control is achieved by effecting the reaction in a cooled falling film absorber having integral cooling passages and to which liquid water is fed to form the falling film. In another embodiment, the reaction is effected in a packed tower with a substantial proportion of the product acid being recycled through an external heat exchanger and diluted with water.

摘要： Alkali metal sulfates are produced from an aqueous solution containing alkali metal hydrogen sulfate which comprises contacting the aqueous solution of alkali metal hydrogen sulfate with a hydrophilic solvent, the hydrophilic solvent being effective to extract at least a portion of the sulfuric acid formed as the alkali metal hydrogen sulfate is converted to alkali metal sulfate in the solution, together with at least a portion of the water present; permitting the alkali metal sulfate solid to crystallize; and recovering the solid alkali metal sulfate product. The hydrophilic solvent may then be extracted and separated from the sulfuric acid with a hydrophobic solvent and both solvents can be recovered and recycled.

摘要： Carbon dioxide is produced from oxyfuel fired glassmaking furnace effluent gas by a series of steps including quenching the waste gas with aqueous quench liquid, comprising a solution of carbonate having a pH in the range of 6-5 to 8, thereby cooling the effluent gas and converting at least part of said sulphate to particulate sulphur salt, filtering particulate sulphur salt from the gas, and returning the particular sulphur salt to the furnace. The filtered gas is preferably scrubbed with aqueous carbonate to convert any remaining sulphur dioxide to an aqueous sulphite suspension and using the suspension as part or all of the above-mentioned aqueous quench liquid. The sulphur dioxide-free waste gas is preferably contacted with ammonia in the presence of a catalyst that selectively converts nitrogen oxides to nitrogen, thereby removing substantially all nitrogen oxides from the waste gas, and the resulting effluent gas stream is separated to produce a pure carbon dioxide product. The catalytic conversion is preferably performed in a series of at least two reactors, the feed gas temperature decreasing and the ratio of ammonia to total nitrogen oxides increasing as the feed gas passes from reactor to reactor.

摘要： A process is described for recovering alkali-chloride and alkali-sulfate salts from a salt solution. The salt solution comprises alkali metal, chloride and sulfate ions and is directed to a hydrous salt crystallization unit which crystallizes hydrated sulfate salts that comprise sulfate and at least one alkali metal. A purged solution from the hydrous salt crystallization unit is directed to a chloride salt crystallization unit while the hydrated sulfate salt crystals are melted to form an aqueous sulfate solution which is directed to a sulfate crystallization unit. Anhydrous sulfate salts are crystallized from the aqueous sulfate solution to form sulfate salt crystals comprising sulfate and at least one alkali metal. In the chloride salt crystallization unit, chloride salt is crystallized to form chloride salt crystals. A purge from the chloride salt crystallization unit is directed to the hydrous salt crystallization unit.

摘要： Magnesium oxide produced by a process is used as a neutralizing agent for preliminary neutralization treatment of a leached slurry obtained by leaching a nickel oxide ore at a high temperature and pressure with sulfuric acid added. A neutralizing agent is added to a leachate, obtained by leaching a nickel oxide ore, to separate impurities, and a sulfurizing agent is added to the resulting neutralized solution to obtain nickel and cobalt sulfides, followed by separating the sulfurized solution; discharge waste water, obtained by adding a neutralizing agent to the sulfurized solution to separate aluminum and manganese, is concentrated to precipitate and separate calcium contained in the discharge waste water as calcium sulfate; the resulting solution is concentrated to precipitate magnesium in the solution as magnesium sulfate; the magnesium sulfate is roasted with a reducing agent to obtain magnesium oxide and a sulfurous gas; and the magnesium oxide is washed.

摘要： This invention relates to processes for selective removal of contaminants from effluent gases. A sulfur dioxide absorption/desorption process for selective removal and recovery of sulfur dioxide from effluent gases utilizes a buffered aqueous absorption solution comprising weak inorganic or organic acids or salts thereof, to selectively absorb sulfur dioxide from the effluent gas. Absorbed sulfur dioxide is subsequently stripped to regenerate the absorption solution and produce a sulfur dioxide-enriched gas. A process for simultaneous removal of sulfur dioxide and nitrogen oxides (NOx) from effluent gases and recovery of sulfur dioxide utilizes a buffered aqueous absorption solution including a metal chelate to absorb sulfur dioxide and NOx from the gas and subsequently reducing absorbed NOx to form nitrogen. A process to control sulfate salt contaminant concentration in the absorption solution involves partial crystallization and removal of sulfate salt crystals.
