OPT800 Cook/B brings Advanced Process Control to batch digesters to ensure optimal cooking conditions for all chips charged to each digester. This leads to decreased variation in pulp quality compared to conventional control methods. It also has a steam leveling function, to effectively minimize variations in total steam demand by adjusting to the actual needs of the digesters.
OPT800 Cook/B is an advanced process control (APC) solution for controlling, monitoring and reporting on batch digester house operations for overall cooking optimization. It’s accomplished by maintaining a steady Kappa number and even cooking by using the built-in Kappa control module that works in sync with the H factor control.
This APC solution can be applied to different types of digester houses including direct/indirect steaming, cold blow and displacement cooking methods such as Rapid Displacement Heating (RDH) or SuperBatch, varying cooking sequences, special batch digester house configurations and for both the sulphate and sulfite processes.
The result is consistently high pulp quality coming out of the entire batch digester house, with the lowest raw material and energy inputs.
