|Obtain better white liquor quality, stabilized causticizing efficiency, and sulfur and alkali indices, plus lime and natural gas reduction.
The online measurements and advanced controls have stabilized the entire chemical conversion process and allowed the target shifting of key process indicators. With improved stability, overliming has also been eliminated.
After only a few months of operation, the results of the project were seen in:
