Closed-loop optimization and other advanced process control techniques provide considerable value to the hydrocarbon processing industry. A critical factor to the success of an optimization application is its onstream factor. An optimization application may be turned off for several reasons such as inaccurate models, exceptional operating conditions or invalid constraints. Rule-driven optimization is increasingly used to make the real-time decisions necessary to keep an optimization application online (Fig. 1).    Fig. 1
