desulfurization

Desulfurization is the process of removing sulfur or sulfur compounds from substances like coal, flue gas, molten metals, or petroleum products. This is often achieved through chemical reactions. For example, hydrodesulfurization is a process used in oil refineries to remove sulfur from petroleum products by mixing them with hydrogen and a catalyst, producing hydrogen sulfide. In flue gas treatment, scrubbers using alkaline sorbents or seawater are employed to remove sulfur dioxide, a pollutant that can cause respiratory issues and acid rain.1234
