What is Desulfurization? (with pictures)

17/02/2021  Jeri Sullivan Date: February 17, 2021 Scrubbers can be used to help desulfurize the exhaust from power plants.. Desulfurization is the process of removing sulfur from something to prevent contamination. Also known as hydrodesulfurization or HDS, this chemical process reduces the sulfur dioxide emissions and converts them to sulfuric acid.

Desulfurization - an overview ScienceDirect Topics

The Sulfinol process, which is a combination process that uses a mixture of amines and a physical solvent (Sulfolane), has been used in the Buggenum plant (Hannemann et al., 2002). This process can achieve a high degree of H,S selective removal with less than 40 ppm v , sulfur in cleaned syngas ( Korens et al ., 2002 ).

Flue-Gas Desulphurization - an overview ScienceDirect

Flue-gas desulfurization (FGD) material is a product of a process typically used for reducing SO 2 emissions from the exhaust gas system of a coal-fired boiler. The physical nature of these materials varies from a wet sludge to a dry, powdered material depending on the process. The wet sludge from a lime-based reagent wet scrubbing process is predominantly calcium sulfite. The wet
