Aspen RTO™

Plant-wide, real-time, closed-loop profit optimization

Aspen RTO provides a comprehensive solution to the challenge of optimizing process profitability, determining the optimal targets for individual process units and considering the conditions across the entire process. It provides robust convergence for real-time solutions with models detailed enough to address true unit economics. Aspen RTO is a core element of AspenTech’s aspenONE™ Advanced Process Control applications.

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
  • Can incorporate 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
