Lime in Pulp and Paper Mills
The caustic soda is pumped off to once again mix with the wood chips, and the calcium carbonate is conveyed to a kiln where it is heated to convert it to lime (calcium oxide or CaO). This lime is mixed with water, forming slaked lime. The sodium carbonate returning from the pulping process is than added to the mixture to form caustic soda ...

LIME SLAKING 101
In many of these applications, hydrated lime, or calcium hydroxide (Ca(OH) 2), is used. This is produced by adding water to quicklime (calcium oxide, CaO). Initially forming a dry hydrated lime product, the further addition of water creates a hydrated lime slurry in a process known as slaking—the focus of this white paper. Publication Date:
