Lime Slurry

Arthur L. Kohl, Richard B. Nielsen, in Gas Purification (Fifth Edition), 1997 Process Description. The overall effects of the double alkali process are identical to those of the limestone/ lime slurry processes—SO 2 is removed from the gas, lime or limestone is consumed, and a calcium sulfite or sulfate by-product is produced. The intermediate steps, however, are quite different and result ...

EXPERIENCE IN EFFECTIVE APPLICATION OF METALLIC …

flue gases mix with the limestone slurry. The conditions are cooler (typically 130 to 160°F/ 54°C to 71°C) and the pH is higher (typically 4.0 to 5.5). Newer absorbers are often designed so that the walls are continuously washed by the slurry to avoid formation of deposits which can induce crevice corrosion. Spray Headers and Mist Eliminators

Flue-gas desulfurization

SO 2 is an acid gas, and, therefore, the typical sorbent slurries or other materials used to remove the SO 2 from the flue gases are alkaline. The reaction taking place in wet scrubbing using a CaCO 3 slurry produces calcium sulfite (CaSO 3) and may be expressed in the simplified dry form as: . CaCO 3 (s) + SO 2 (g) → CaSO 3 (s) + CO 2 (g). When wet scrubbing with a Ca(OH) 2 (hydrated lime ...

Presentation of Wet Flue Gas Desulphurisation Technology

Limestone slurry is prepared mixing fine limestone powder with water in a slurry preparation tank. Sorbent slurry from this tank is then pumped into the absorber reaction tank. The absorber is a counter-flow tower with flue gas flowing upwards, while limestone slurry …

limestone and viscosity

limestone and viscosity. Good day. In our quarry we came across 2 types of limestone (C&G). Our target viscosity is 2.5% (a wet process plant and therefore we have to pump), however, with stone C we find that we can use about 3% less moisture than stone …

Lime Production

Lime Production. In order to purify the beet raw juice, SMBSC produces the lime, for the manufacture of the calcium hydroxide slurry (milk of lime), and the carbon dioxide gas - both needed for the carbonation process. These two chemicals are produced by calcining (burning) of limestone in vertical kilns, using foundry coke as a fuel.

Managing acid sulfate soils

Limestone application methods can include large-scale aerial dosing, limestones barriers, and the localised application of limestone slurry to acidified waters. As environmental (water level and quality) conditions in the CLLMM region are currently stable, the Managing Acid Sulfate Soils project is currently on standby until triggers for limestone

FGD SLURRY DENSITY MEASUREMENT

 · Due to it''s low-cost and availability, limestone is the most extensively used reagent. The lime-stone slurry reacts with the flue gas in the absorber, removing the SO 2. The limestone in the slurry is converted into calcium sulfite, air is then introduced and oxidizes the sulfite into calcium sulfate which is then filtered and dewa-tered.
