摘要： A method for controlling the concentration of dissolved thiosulfate byproduct which forms in a wet desulfurization process, by introducing a peroxygen chemical into its recirculating aqueous absorption medium. A peroxygen chemical such as aqueous hydrogen peroxide is introduced into the recirculating aqueous alkaline absorption medium, preferably after its regeneration, in an amount sufficient to maintain the concentration of thiosulfate byproduct below a saturation concentration. The method is applicable to cyclic wet desulfurization processes, used to recover elemental sulfur from H.sub.2 S-containing gas streams, in which the absorption medium contains a regenerable oxidizing agent and is subject to thiosulfate byproduct buildup.

摘要： Hydrogen sulfide is effectively removed from potable water by the combined action of first chlorinating the water and then passing the chlorinated water through a bed of activated carbon. Chlorine is added in large doses to potable water containing dissolved hydrogen sulfide to convert substantially 90% of the hydrogen sulfide to sulfates. The chlorinated water containing residual hydrogen sulfide is then passed through a bed of activated carbon. Chemisorbed nascent oxygen in conjunction with the activated carbon catalytically affect breakdown of the remaining sulfide compounds into elemental sulfur.

摘要： Stack gases from fossil fuel burning operations before being released to the atmosphere are passed through a scrubber, wherein sulfur dioxide is removed from the gases by scrubbing with metallic carbonates. The metallic carbonates react with the sulfur dioxide to form a liquid effluent comprising metallic sulfates. The effluent is placed in a basin and inoculated with a microorganism which reduces sulfate ions to hydrogen sulfide, preferably bacteria from the genus Desulfovibrio, thereby also regenerating metallic carbonates. The effluent is contemporaneously or serially inoculated with saline compatible bacteria from the genus Beggiatoa whereby the hydrogen sulfide is oxidized to form sulfur. After treatment by the bacteria, the effluent is recycled to the scrubber for use therein and the sulfur is recovered.

摘要： A liquid solution containing a tri-halide from the halogen group consisting of bromine and iodine is passed in countercurrent flow with fluids containing sulfur compounds, including hydrogen sulfide, within a tower. The tri-halide solution removes selected sulfur compounds, including hydrogen sulfide, from the fluids and the halide solution is drained from the bottom of a tower for sulfur removal, electrolytic regeneration, and hydrogen release in order that a tri-halide from the electrolytic cell may be returned to the tower for continual removal of sulfur compounds, including hydrogen sulfide. A portion of the spent halide solution from the bottom of the tower is conducted to a point in the tower above the introduction of the tri-halide solution to prevent the loss of the diatomic halogen.

摘要： A process for the removal and conversion into sulfur of hydrogen sulfide in a gaseous or liquid material which comprises essentially treating the said material with an oxidative lignin prepared by treating lignins with oxidizing agents, nitrating agents and/or demethylating agents and, if desired, introducing hydrophilic groups into the resultant product. The lignins include protolignin, isolated lignins and other denatured lignins. The process is advantageous essentially in that hydrogen sulfide can be removed economically and converted completely into sulfur, and that the desulfurization agents, i.e. the oxidative lignins, are non-toxic and non-corrosive.

摘要： The invention is an improved method for regenerating liquid streams which contain sulfur dioxide. The method comprises providing a body of liquid which contains sulfur dioxide having a free space above the surface; forming a mixture of gas bubbles in the liquid by admixing a sufficient amount of gas containing hydrogen sulfide with the liquid to react with the liquid to form sulfur and to provide a sufficient amount of gas bubbles to separate sulfur formed from the body of the liquid by flotation. The method is particularly useful for regenerating aqueous absorbents in cyclic processes for removing sulfur dioxide from gas streams.A preferred method is to admix a sufficient amount of a gas containing hydrogen sulfide with a whirling mass of aqueous absorbent in the body of aqueous absorbent and passing the mixture through a zone of stationary apertures wherein the size of the gas bubbles in the mixture is reduced and whereby hydrogen sulfide in the gas is reacted with the aqueous absorbent to form sulfur and the sulfur is floated to the surface of the body of absorbent by the rising gas bubbles and recovered.The absorbent can be substantially regenerated and a major portion of the sulfur separated from the aqueous absorbent by this procedure.
