Sulfur refining process
Weballurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin-tering, into a primary smelter. Lead concentra-tions can be 50–70%, and the sulfur content of sulfidic ores is in the range of 15–20%. Zinc con-centration is in the range of 40–60%, with sulfur content in sulfidic ores in the range of 26–34%. WebSulfur is a major by-product of oil refining and gas processing. Most crude oil grades contain some sulfur, most of which must be removed during the refining process to meet …

WebIn the refining process, crude oil is heated in a furnace, which is then sent to the distillation unit, where heavy crude oil separates into lighter components called fractions. One of these, called naphtha, is the crucial compound to make a large amount of plastic. However, there are other means, such as using gas. Figure 1. Web15 Jan 2014 · This is the most widely used and cheapest process of refining sugar as compared to other available process. However the major drawback of the Sulphitation proecsss is that Sulphur enters sugar during its refining process.

Use of electrical cells equipped with inert cathodes is the most com … WebClaus plants play a key role in refinery productivity. They process concentrated hydrogen sulfide (H 2 S) fractions, converting them into sulfur dioxide (SO 2) and ultimately elemental sulfur They can also remove pollutants, particularly those caused by decomposing ammonia.. Today, many refinery operators are challenged to manage rising H 2 S levels. …
WebSulfur recovery refers to the conversion of hydrogen sulfide (H2S) to elemental sulfur. Hydrogen sulfide is a byproduct of processing natural gas and refining high-sulfur crude oils. The most common conversion method used is the Claus process. Approximately 90 to 95 percent of recovered sulfur is produced by the Claus process. WebA process comprising contacting a solvent with a sulfur stream comprising sulfur and a contaminant, separating the sulfur from at least some of the contaminant and at least …
WebVarious processes used in treating are hydrodesulfurization, hydrotreating, chemical sweetening, desalting, deasphalting, hydrogen sulfide scrubbing, and acid gas removal. The selection of a proper treatment method is dependent on various factors like: the nature of the petroleum fractions,
