Aspen Polymer Production Control™

The most complete control solution for polymers production

Efficiently managing on-grade production and grade transitions is critical to profitability. Aspen Polymer Production Control provides full automation and dynamic optimization of product grade transitions while delivering significantly improved product quality. As a result, companies can lower costs, produce less waste, increase production, and achieve specification faster to deliver increased margins. Aspen Polymer Production Control is a core element of AspenTech’s aspenONE™ Advanced Process Control applications.

Features

  • Full non-linear model-predictive control
    • Constraint ranking: Ranks targets and limits for different variables so that under certain conditions, the optimizer will prioritize higher ranked constraints first.
    • Variable dynamics support: Adjusts model dynamics online in real-time, including dead times.
    • Gain constrained dynamics: Provides accurate modeling of non-linear gains across the entire operating space.
    • Reduced modeling complexity: Captures all relationships in a single model per controlled variable. All parts of the solution reference the same model.
  • Integrated transition management: Fully optimizes the complete range of transitions including those with:
    • Reactor configuration changes (series to parallel, parallel to series)
    • Catalyst and donor changes
    • Large. simultaneous changes in multiple product-quality targets
    • Multiple reactors in series
    • Variable dead times and dynamics
  • Integrated recipe management
    • Change reporting
    • Recipe value downloading
    • Role based security: Allows particular features in Aspen Process Recipe to be secured by user roles.
    • Flexible item types: Defines and maintains parameters, item types, and parameter associations.
    • Recipe item parameter ‘”matrix” view: Provides the ability to view all control recipe items
    • Embedded calculation engine from Aspen Calc

Benefits

  • Increases capacity from existing assets by 3% to 5%
  • Improves quality by reducing process variability by up to 75%
  • Flexible scheduling⎯breaks the “product wheel” approach to scheduling
  • Captures and uniformly implements best practices and operating procedures
  • Provides for local control recipes
  • Reduces transition waste by 25% to 50%
  • Maximizes production rates to unit performance constraints
  • Reduces in-grade, off-specification production by 50% to 75%
