Sulfur Dioxide Emissions Sulfur dioxide (SO2) belongs to the family of sulfur oxide (SOx) gases. These gases are formed when fuel containing sulfur (mainly coal and oil) is burned (e.g., for electricity generation) and during metal smelting and other industrial processes. High concentrations of . the smelter oven is fed with air or oxygen-enriched air and produces an offgas containing large amounts of sulfur dioxide. membrane technology and research, inc., has developed a class of membranes that is extremely selective for sulfur dioxide over other gases. in the phase i program, a laboratory system that includes a spiral-wound module.

Most Japanese copper smelters are located in areas of concentrated industrial activity and high levels of atmospheric pollution. A review of unofficial sulfur dioxide emission control data from major Japanese smelters shows capture of 91 to percent of the sulfur in the smelter feed.

Program Element No. 1AB ROAP No. Sulfur Dioxide Emissions From Copper Smelters  Copper smelting, involving extraction of copper from chalcopyrite (CuFeS2), liberates large quantities of sulfur gases: 2 tons of SO2 are discharged in flue gases (which also contain CO2 and NOx) per ton of copper produced.
Smelters have long been recognized as significant sourcesFile Size: KB. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting, charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ore) is heated in air to about °C (°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2).
Portions of impurities such as antimony. The biggest problem area in sulphur-dioxide emission control at smelters arises from converting which utilizes rotary side-blown converters (Peirce-Smith converters) and the transfer of molten material in ladles, both open processes which release off-gases including sulphur dioxide into the air.
This paper estimates the cost of the abatement of sulfur dioxide (SO 2) for three copper smelters operating in analyses compliance with emission goals and with the atmospheric health-based SO 2 and breathable particle standards.

Sulfur dioxide is a colorless, toxic gas with pungent odor formed when sulfur is oxidized: S+O SO 2→ 2 (1) Sulfur dioxide is highly soluble in water, forming sulfurous acid (H 2SO 3).

Smelting is a process of applying heat to ore in order to extract a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base ng uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Sulfur dioxide and nitrogen oxides are the chief precur- sors of acid rain, and their continued emission into the atmosphere has become a global concern. It is estimated that million tons are emitted from industrial processes yearly, mainly from nonferrous metal smelting operations.
To meet the new EPA sulfur dioxide standards, ASARCO launched a converter retrofit program to replace the smelter’s five ft.
diameter converters with three ft. diameter converters, install improved primary and secondary hoods, and an electrostatic precipitator for solids removal prior to recapturing sulfur dioxide in acid baths.

This paper presents a summary of the cost of copper smelting at eight southwestern U.S. plants, as of From these cost data and collateral engineering data estimates were made of the costs for unrestricted smelting (no sulfur capture), and for recovering 90% and 98% of the sulfur.

Abstract. A year-long record of the sulfur dioxide (SO 2) emission rate of Asama volcano, Japan, is presented including high-temporal-resolution data since the and – eruptive activities were associated with high SO 2 emission, and SO 2 emission rates markedly fluctuated.
