Nozzle design and alignment are critical in these systems, as droplet size and spray patterns must be optimized to provide the best contact and to prevent channeling of the flue gas. That the spray nozzle design has become much better 2 is the key to this development. Limestone utilization in the scrubber is another important issue.

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 schematic of Lime Spray Dryer (LSD) with optional Furnace Sorbent Injection (FSI) is shown in Fig. 3.19. The lime slurry is finely distributed by rotary atomizers or nozzles into the flue gas. As the slurry mixed with hot flue gas, some water is evaporated. The remainder water in the sorbent promotes the reaction with SO 2. The desulfurized ...
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 ...
Limestone is mixed with water in a slurry supply tank. The fresh limestone slurry is fed to the absorber sump. The limestone/gypsum slurry is pumped from the absorber sump (holding tank) up to the horizontal spray headers at different levels at the top of the scrubber. Normally, the number of spray levels varies from 4 to 6.

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 are able to effectively and reliably distribute these slurries into absorption towers.
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.
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).
The wet FGD method is widely used and employs limestone/ lime or seawater slurry as absorbent material to reduce SO2 prior to exhausting process gases to the atmosphere. …
