Limestone Scrubbers. The flue gas is led through a scrubber where limestone slurry is added via spraying. The limestone reacts with the SOx in the flue gas and its products are removed from the gas. A following demister stage removes water droplets. This scrubber is a type of spray tower without internals and is operated in counter current.

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
