burning limestone to make lime

Lime in the Pulp and Paper Industry - ANSI Blog

Slaked lime is essential to this process. The kraft process begins by mixing caustic soda (NaOH) with the initial wood chips under high heat and pressure. 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.
