Sulfur dioxide is primarily used for chemical manufacturing, pulp and paper processing, and as a food desiccant and preservative. It is also commonly used in ore processing, as a fungicide, wine production, and natural gas
Sulfur compounds such as the sulfates of iron and aluminum are used successfully in the coagulation of water and sewage. Recently Schwartz (6) reported that the use of ferric sulfate and lime was the most efficient process for removing silica from water. The use of sulfur dioxide with alum for color removal is an interesting develop-
1 paź 2021 · The rates of sulfur dioxide (SO 2) and nitrogen oxides (NOx) contributing to air pollution have risen annually, imposing huge burdens on human health and industrial production. Among gas separation techniques, wet scrubbing exhibits superior economical and application value to simultaneously remove SO 2 and NO X .
There, it reacts with water to form clouds of Sulfurous acid (SO2 + H2O ⇌ HSO−3+ H+), and is a key component of the planet's global atmospheric sulfur cycle and contributes to global warming. [13] .
15 paź 2018 · The recovered sulfur can be used as a raw material in industry and agriculture to produce sulfuric acid, sulfur fertilizers and fungicides (Chung et al., 2013). H 2 S reaches concentrations ranging from 500 ppm v to 20,000 ppm v in biogas from anaerobic digestion or industrial gas streams in natural gas processing ( Pokorna and Zabranska, 2015 ).
21 sty 2021 · The objective of the present work, which is being patented, is to develop an improved method for combining the catalytic oxidation of nitrogen oxides (NO X) and sulfur oxides (SO X) in flue gases, which eliminates the need for a gaseous ozone/hydrogen peroxide oxidation stage.
25 gru 2023 · Sulfur-containing organic wastewater, often emanating from sectors such as petroleum refining, chemical manufacturing, and pulp and paper processing, exhibits a set of distinct physicochemical properties.
