Red mud desulfurization is an environmentally friendly desulfurization technology. After desulfurization, the acidity of red mud slurry continues to be neutralized for processing new red mud, and no waste acid is generated. At present, there is a lack of research on desulfurization intensification in external fields, etc. To further enhance red mud desulfurization, this paper used an SO2 ...

The semidry desulphurisation process is particularly suitable for systems up to 1 million Nm 3 /h flue gas. To purify the gases from SOx, but also from other acid components like HCl and HF, an aqueous absorbent ( lime slurry) is injected into the spray absorber. The acidic harmful gases react with the absorbent to form salts, while at the ...
