Constraints
If there is a mismatch in pulp demand and minimum or maximum production, best use will be made of the available capacity in the storages to maintain production.
Constraints include white liquor supply, black liquor processing, or plant throughput. The plant bottleneck may change from day to day.
If pulp mill production is limited by white liquor supply or evaporator throughput, the maximum production rate is calculated according to the current priorities and available capacity in the white liquor or WBL systems.
