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
