Fossil Free drives carbon negativity. Lime mud reburning in the Kraft process used in pulp/paper/board production is a major source to CO2emissions. The lime kiln is often the last big consumer of fossil fuels in the mill. In Sweden many lime kilns have been converted to biofuels, which instead means that great amounts of biomass are consumed.

The most common method for the preparation of slaked lime is via the reaction between calcium oxide (also known as quicklime) and water. When combined with water, a relatively small proportion of the quicklime dissolves, resulting in the formation of a solution known as limewater. The remainder of the quicklime remains in a suspension, which is ...

Lime slaking is the process of converting quicklime to hydrated lime (CaO + H20 > Ca (OH)2) by mixing with water. Lime slaking is an exothermic process which generates heat and creates steam. Slaked or hydrated lime is often used in mining and process industries for raising pH or neutralising acidic solutions.

Hydrated lime also called slaked lime is produced when water is added to calcium oxide (CaO, or quicklime). The result of this mixing of water and calcium oxide (quicklime) is an exothermic reaction known as slaking. The slaking reaction produces calcium hydroxide, (Ca (OH) 2 ). Initially, the calcium hydroxide is produced as a fine dry powder.
