What is Desulfurization (with pictures)Info Bloom

Jeri Sullivan 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. The sulfuric acid is then used in car batteries and fertilizer.
