Summary of research progress on industrial flue gas desulfurization
Red mud and water are used to make red mud slurry for wet desulfurization. P. Wei used an absorption tower to use a red mud slurry for desulfurization. The optimal operating conditions were as follows: L/S was 7:1 (g/g), empty tower gas velocity was 0.35 m/s, L/g was 12:1 (L/m 3), and inlet SO 2 concentration was 1700 mg/m 3.

Semi-dry flue gas desulphurization in spray towers: a
Flue gas desulphurization (FGD) is a technology that has been adopted to scrub SO 2 from flue gas (es) generated from coal-fired power plants. The absorption of sulphur dioxide (SO 2) is achieved by contacting the hot FG with an alkaline sorbent. FGD technologies are classified into three broad categories: wet FGD, semi-dry FGD and dry FGD.
