About this site

Most FGD systems employ two stages: one for fly ashremoval and the other for SO 2 removal. Attempts have been made to remove both the fly ash and SO 2 in one scrubbing vessel. However, these systems experienced severe maintenance problems and low removal efficiency. In wet scrubbing systems, the flue gas normally passes first through a fly ash removal device, either an electrostatic precipitator or a baghou

What is Desulfurization? (with pictures)

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.
