Lime in the Pulp and Paper Industry
After attacking the wood's lignin, the caustic soda is converted to sodium carbonate (Na 2 CO 3), which is then pumped into a vessel containing slaked lime. With the introduction of slaked lime, the two react to form calcium carbonate and caustic soda, the latter of which is once again mixed with wood chips to continue the process all over again.
