Grade transition modelling in continuous pulp digesters for reaction profile control - It has been used in a simulation to measure the effectiveness of MPC
Fj. Doyle et al., Grade transition modelling in continuous pulp digesters for reaction profile control - It has been used in a simulation to measure the effectiveness of MPC, PULP PAPER, 102(6), 2001, pp. 56-59
The modelling of softwood to hardwood grade transitions is described in a c
ontinuous pulp digester. Validation with industrial data is presented. A mo
del-based control strategy is introduced to minimize the production of off-
specification or "twilight" pulp, and the results are compared to conventio
nal manual control strategies.
