The application discloses a system for controlling a chemical manufacturing process having at least one piece of process limiting equipment in addition to a reactor. The system employs one or more multivariable predictive optimizer controllers for optimizing control of the chemical reactor and production limiting equipment located upstream or downstream of the reactor, to provide integrated process control of the reactor and the production limiting equipment.
