Product Brochure

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
