Lime In Pulp And Paper Mills | Graymont

Lime is used in several applications within pulp mills. One of the most common applications is for the sulfite-pulping process. This process uses acid to dissolve the glue (lignin) that holds the fibers (cellulose) together. When acidic water discharged from this process is neutralized, lime is the reagent of choice in order to safely elevate ...

Rotary Lime Kiln Operation

Rotary Lime Kiln Operation

Nov 28, 2016 Rotary Lime Kiln Operation. Metallurgical Content. Precipitated calcium carbonate, commonly called lime sludge or lime mud, is produced when sulphate green liquor is causticized with lime. For many years this lime sludge was considered a waste product and was dumped into rivers or waste ponds, or used for fill around the plants.

Pre-Industrial Lime Kilns - Historic England

Pre-Industrial Lime Kilns - Historic England

This IHA provides an introduction to pre-industrial lime kilns. A lime kiln was a structure used to manufacture lime (calcium oxide) by burning calcium carbonate at temperatures above 900 C. The calcium carbonate burned (or ‘calcined’) was commonly limestone or chalk, but occasionally other materials such as oyster or egg shells were used.

Lime Processes. The dissociation of limestone (calcium carbonate) into quicklime and carbon dioxide at temperature is a process known as calcination i.e., CaCO 3 = CaO + CO 2 ΔH = -760 BTU/lb CaCO 3. Magnesium Carbonate, which is found in some quantities with limestone deposits, also dissociates according to the reaction: MgCO 3 = MgO + CO 2 ...
