Advanced Process Control - Evaporation Control
Opportunity: Evaporation Control.
Solution: The purpose of evaporation is to concentrate the black liquor. Manual control of evaporation represents a challenge because the difficulty of controlling the process in a synergistic way is considerable high. Another reason is that this stage has the highest vapor consumption of the whole plant. Overall, evaporation is a difficult operation process, associated with a great cost of utility. With the optimizing control for the process in question, the objective is to stabilize the content of the black liquor concentrate and reduce the vapor consumption.
Result: A reduction of 2 to 5% in specific vapor consumption is expected.
