— Conventional real-time optimizers are based on steady-state models and their effectiveness on plants with long-lived dynamics are thus limited. This is particularly true for tightly integrated plants with material recycle loops and other mass / energy integration loops, which tend to show distinct timescale separation in their dynamic behavior. The use of(More)
An integrated plant with large material and energy recycle loops is known to exhibit a multiple timescale phenomena, in which the fast dynamics arise from the change in the unit operations and the slow dynamics are induced by interactions from the recycle streams. When the recycle-to-feed ratio is very large, the system becomes extremely ill-conditioned and(More)
