ABSTRACT:
In the cycle for production of pulp by the Kraft process, the active alkali concentration range in black liquor is monitored and adjusted. In recognition of the effect of the proportion of the active alkali to the other contents of the black liquor on a dry solids basis, active alkali is adjusted to control various performances of the evaporators and combustion within the recovery furnace.
