Dynamic Real Time Optimizer (RT-OP)

What is Dynamic Real Time Optimizer (RT-OP) ?

Dynamic Real Time Optimizer (RT-OP) is a dynamic real time optimization solution which optimizes an asset (e.g. LNG), an entire plant (e.g. olefins) or circuit within a refinery / petrochemical plant to ensure it is continuously responding to market signals and disturbances (such as feed changes), on a few minutes’ basis. The solution combines Petro-SIM models and Platform for Advanced Control & Estimation (Advanced Process Control).

 

Key Features of Dynamic Real Time Optimizer (RT-OP)

• Changes to the independent variables are captured by dynamic coordination every few minutes
• Dynamic Real Time Optimizer (RT-OP) encompasses an entire asset or multiple process units where the plant can be segregated into blocks  
• Dynamic Real Time Optimizer (RT-OP) can be achieved through the unique technology combination of PACE and Petro-SIM
• Dynamic Real Time Optimizer (RT-OP) leverages the leading first principle non-linear process model, Petro-SIM. This means inferential calculations (e.g. furnace severity, catalyst degradation, catalyst circulation rate, distillation column tray loading) can be generated by Petro-SIM and be used as inputs to the PACE Controller as extra targets and constraints

How Does Dynamic Real Time Optimizer (RT-OP) Work?

• Dynamic Real Time Optimizer (RT-OP) variables are the same as APC variables
• Economic objective function is solved using state-of-art technology
• Optimal CV targets are used in the control layer
• Petro-SIM first principles model performs "inferential calculations including feed quality" and provides "gain updates when they change"
