ACE Control Systems (evaporation

ANDRITZ Evaporator ACE is a control optimization system powered by BrainWave that stabilizes level and differential temperature in each of the effects and stabilizes the black liquor solids.

ACE starts by closing loops and stabilizing operations with the patented BrainWave controller. Then BrainWave develops response models of the solids, effect level, boiling points and other specified loops based on the control actions and system responses observed during normal operation of the evaporation plant. In developing these models, BrainWave takes account of the dead time, while also including measured disturbances like incoming steam pressure, inlet weak black liquor percent solids, and production rate.
