In 2012, US oil refineries recovered 7.4 million metric tons of sulfur, worth about $915 million, and amounting to 88% of the elemental sulfur produced in the US. [13] Sulfur removal (as well as other contaminants) was a key theme of US refinery investment during 1990 to 2017 leading to additional sulfur production.
Like sour oil, there is some natural gas naturally high in sulfur, called sour gas (natural gas with little or no sulfur is called sweet gas). The sulfur is present in the form of hydrogen sulfide, a toxic gas that must be removed for safety reasons. Most natural gas has less than 1 percent hydrogen sulfide, but deposits have been discovered ...

The majority of the sulfur in crude oil occurs bonded to carbon atoms, with a small amount occurring as elemental sulfur in solution and as hydrogen sulfide gas. Sour oil can be toxic and corrosive, especially when the oil contains higher levels of hydrogen sulfide, which is a breathing hazard.
The Galveston Bay Refinery is an oil refinery located in the Texas City, Texas Industrial Complex on the edge of Galveston Bay.It is the largest oil refinery in North America with a capacity of 631,000 barrels per day [1] and has been owned and operated by Marathon Petroleum Corporation since 2013.
In 1950, the company changed its name to the Union Sulphur & Oil Corporation to reflect its transition to oil production. [10] In 1955, the name was changed to the Union Oil & Gas Corporation.

Nornickel said smelters in the Arctic city of Norilsk release roughly 1.8 million tonnes of sulphur dioxide emissions annually. Nornickel cut emissions in Norilsk by 30-35% in 2016 when it shut ...
Sulfur dioxide is a mild but useful reducing agent. It is oxidized by halogens to give the sulfuryl halides, such as sulfuryl chloride: SO 2 + Cl 2 → SO 2 Cl 2. Sulfur dioxide is the oxidising agent in the Claus process, which is conducted on a large scale in oil refineries. Here, sulfur dioxide is reduced by hydrogen sulfide to give ...
