APC Tuning on a Polymer Line
Multivariable reactor temperature/viscosity control — model update loop.
APCPolymer
MIMO model
Temperature, viscosity, and monomer flow are multivariable; weekly online model update stabilizes grade changes in 2 hours.
Safety limits
APC setpoints are bounded by the interlock matrix; hard override to DCS and event log on exceedance.
