Limestone can be professionally cleaned for a fresh, clean look, and sealed to inhibit staining. Etches, scratches, and dullness can be virtually erased with professional honing and polishing. For regular day-to-day care, use a stone-safe, neutral cleaner, and follow the care instructions in our free, downloadable Stone and Tile Care Guide.

Wet Limestone. Wet limestone systems are well established in some sectors such as the Power Generation industry. This process is based on the large degree of contact between the circulating slurry and the flue gases. This slurry circulates in the absorber tower (or scrubber) to neutralize the condensed flue gas pollutant, mostly SO 2.

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).
