Lime / Limestone Wet Scrubbing System for Flue Gas …
BACKGROUND. Wet scrubbers are used in utilities, paper mills, and chemical plants to remove sulfur dioxide (SO 2) and other pollutants from gas streams. Undesirable pollutants are removed by contacting the gases with an aqueous solution or slurry containing a sorbent. The most common sorbents are lime (Ca[OH] 2) and limestone (CaCO 3).
Advanced Process Control for Optimizing Flue Gas Desulfurization
The chemical reaction formula for this desulfurization process is: CaCO 3 + SO 2 + 2 H 2 O +½ O 2 => CaSO 4 + 2 H 2 O + CO 2. SO 2 is absorbed by the CaCO 3 (limestone) thus reducing the outlet ...

State-of-the-Art Upgrades to Existing Wet FGD Systems …
SO 2 removal in a limestone forced oxidized (LSFO) wet scrubber is controlled by how much SO 2 can be absorbed per unit volume of recirculated slurry (lb SO 2 per gallon, or kg per liter). This is referred to as absorption. SO 2 absorption is limited by the amount of solid and liquid phase alkalinity provided in each gallon of slurry. The absorption is also …
A simple realistic modeling of full-scale wet limestone FGD …
Therefore, wet scrubbers, especially wet limestone desulfurization scrubbers, are the front-running FGD technologies [1,2]. In this process, the flue gas is treated with limestone (calcium carbonate) slurry normally in a spray column. Limestone is mixed with water in a slurry supply tank. The fresh limestone slurry is fed to the absorber sump.

FGD Scrubber Nozzles | BETE Gas Scrubbing
Due to erosion, plugging, and build-up concerns, one of the most reliable systems to control these emissions is an open-tower wet flue gas desulfurization (FGD) process using a limestone, hydrated lime, seawater, or other alkaline solution. Spray nozzles can effectively and reliably distribute these slurries into absorption towers.
Flue Gas Desulphuriser Explained
The lower spray decks operate at a pH of approx. 4.0 whilst the higher decks operate at a pH of approx. 6.0 or more. Spray nozzles operate at low pressure, approximately 1 bar (14.5 psi). The alkaline slurry falls from the spray deck to a perforated tray. The perforated tray forces the flue gas to bubble through the slurry as it passes through ...
