GeneralFlame adopts gypsum wet desulfurization: This process uses limestone or lime slurry as an absorbent to react with sulfur dioxide in flue gas, producing calcium sulfite. Subsequently, calcium sulfite is converted to calcium sulfate (gypsum) through a forced oxidation process. The gypsum can be further processed and sold, while the purified flue gas is discharged into the atmosphere. The main reaction steps include: absorption, neutralization, and oxidation.
