TL;DR: In this article, the authors give a critical and detailed introduction to the control and treatment of sulfur oxides (SOx) from operations in the petroleum industry which have negative effects on the environment.
Abstract: Sulfur compounds such as sulfur oxides (SOx) are generated and emitted from operations in the petroleum industry which have negative effects on the environment. This study gives a critical and detailed introduction to the control and treatment of sulfur co...
TL;DR: In this article, a granular bed filter and scrubber with a nitrogen oxide-capturing reducing agent and a bed of sulfur oxide capturing and removing material is used for flue gas removal.
Abstract: A process is provided in which particulates, nitrogen oxides, and sulfur oxides are simultaneously removed from flue gases in a granular bed filter and scrubber with a nitrogen oxide-capturing reducing agent and a bed of sulfur oxide-capturing and particulate-removing material. The spent sulfur oxide-capturing and particulate-removing material can be regenerated in a lift pipe riser.
TL;DR: In this paper, the authors quantitatively determined the sulfur and sulfur compounds involved in the chemical reaction, 3H2SO3= 2H 2SO4+S+H2O in the temperature range from 150 to 300°C, and showed that these two reactions may be responsible for the production of sulfuric acid in hot spring water.
Abstract: Sulfur and sulfur compounds involved in the chemical reaction, 3H2SO3= 2H2SO4+S+H2O in the temperature range from 150 to 300°C have been quantitatively determined. After the disproportionation reaction of sulfurous acid is completed, sulfur decreases according to the chemical reaction, 4S+4H2O = 3H2S+H2SO4. These two reactions may be responsible for the production of sulfuric acid in hot spring water. 34S is enriched in sulfuric acid and depleted in sulfur revealing 16.1 to 21.1‰ fractionation between them. This would account for the enrichment of 34S in sulfuric acid encountered in hot spring water.
