Common methods used: Wet scrubbing using a slurry of alkaline sorbent, usually limestone or lime, or seawater to scrub gases; Spray-dry scrubbing using similar sorbent slurries; Wet sulfuric acid process recovering sulfur in the form of commercial quality sulfuric acid; SNOX Flue gas desulfurization
Flue gas desulphurization detailed process
Flue-gas desulfurization - Wikipedia
In the process of desulphurization the gas is scrubbed with a recirculating limestone slurry, which removes almost 95% of the SO 2 from the flue gas. The process also removes almost all the HCl contained in the flue gas.
24/04/2021 · Flue injection semi-dry flue gas desulfurization: The method uses the flue between the boiler and the dust collector as a reactor for desulfurization, and does not require an additional absorption vessel, so that the process investment is greatly reduced, the operation is simple, and the space required is small, and it is suitable for development and application in my country.
Flue Gas Desulfurization | Yokogawa Canada Wet flue gas desulfurization or scrubber systems are very effective in reducing sulfur dioxide (SO2) emissions caused by coal combustion boilers. The flue gas discharged from the boiler is fed into the absorber where a mixture of water and pulverized limestone is sprayed on the flue gas.
