Aspen Real-Time Optimizer
(formerly Aspen RTO)
Plant-wide, real-time, closed-loop profit optimization
Aspen Real-Time Optimizer provides a comprehensive
solution to the challenge of optimizing process profitability,
determining the optimal targets for individual process units
considering the conditions across the entire process. It provides
robust convergence for real-time solutions with models complex
enough to address true unit economics. aspenONE® Advanced
Process Control is a core element of Aspen Real-Time
Optimizer.
Features
- Profit-based process optimization using large-scale, open-form
model equations based on weighted, user-defined objectives
- Determines optimal targets for the process units
- Incorporates third-party models, such as models of reaction
systems
- Allows user-proprietary models to be easily included in the
real-time optimizer to further leverage past investment and
expertise
- Frequent optimization cycles
- 4-12 executions per day
- Model calibrated to the plant each run
- Uses current economics and constraints
- Model library enables rigorous modeling of petroleum refining,
petrochemical, and chemical processes
- Simplified model maintenance promotes sustainable operation and
higher on-stream factors
- Industry-proven SQP solvers provides increased robustness and
improved diagnostics
- Runs on economical, industry-standard Intel platforms with
Microsoft® Windows 2000, Windows XP, and Windows 2003 Server
operating systems
- Optimization can run unattended with no engineer or
operator-intervention required
- Can be configured to run in either open-loop, sending results
to the plant information system or DCS, or closed-loop, sending
optimal targets to the lower-level advanced control strategy
Benefits
