Why put your models online?

Aspen OnLine enables the online execution of rigorous engineering models for offline or online profit optimization. Connecting simulation models to plant data is a key step to making models more useful for operational decisions.

Models provide real-time operational guidance to help you effectively tackle fluctuations in the market and in operation conditions, such as:

  • Changes to feedstock availability
  • Changes to market demand for products
  • Price variation, safety, etc.

Benefit from real-time operations support advisory.

Real-time advisory systems provide a comprehensive, rigorous solution to the challenge of optimizing the profitability of your process in real time. Solutions with high-fidelity models can address the true economics of your plant or site in advisory mode.

  • High-fidelity, first principle models applied for petroleum refining, petrochemical and chemical processes
  • Process optimization is based on a user-defined objective, usually for operating profit using marginal costs of feeds, products and utilities 
  • Industry-proven, equation-oriented modeling technology provides fast and robust solutions and improved diagnostics

Know when equipment performance starts to degrade.

With Aspen OnLine, you can continuously monitor the performance degradation of key processes, such as:

  • Column flooding
  • Degradation on tray/packing efficiency
  • Catalyst deactivation in reactors
  • Heat exchanger fouling

Maximize Advanced Process Control (APC) benefits with real-time, closed-loop optimization.

Leverage your online models for validation of consistent real-time optimization (RTO), APC model gains and for generating/validating additional inferred quality constraints for APC strategy.

Faster online model deployment.

In V10, use the new Plant Data feature to connect and validate your models with plant historian and/or lab data without leaving the Aspen Plus® or Aspen HYSYS® simulation environment. Aspen OnLine project files are automatically generated by the Plant Data feature and can be deployed online to provide real-time operations support.
