Aspen Plus Dynamics®
Dynamic simulation and optimization of chemical processes
Aspen Plus Dynamics extends Aspen Plus steady-state models into dynamic process models, enabling design and verification of process control schemes, safety studies, relief valve sizing, failure analysis, and development of startup, shutdown, rate-change, and grade transition policies. Aspen Plus Dynamics is a core element of AspenTech’s aspenONE® Engineering applications.
Features
- Easy conversion of steady-state Aspen Plus® models into dynamic models.
- Compatible with Aspen Custom Modeler®, enabling custom user-defined unit operations within Aspen Plus Dynamics.
- Best-in-class physical properties through integration with Aspen Properties®.
- Optimization and estimation tools enabling parameter fitting, data reconciliation, and steady-state and dynamic process optimization.
- Equation-oriented architecture allowing fast and robust simulation of complex, highly integrated processes.
- Flexible Task Language to define transition schemes or to simulate equipment failures.
- Library of equipment models including rigorous reactive distillation with hydraulics and a full set of pressure relief models.
- Library of control models to simulate process control systems including links to Aspen DMCPlus® and Simulink®.
- Choice of flow-driven or pressure-driven simulation for quick, high-performance simulation or rigorous, high-fidelity simulation.
Options
- Aspen Model Runner™ is an execution environment which can be used to run process models exported from Aspen Plus Dynamics. Use Aspen Model Runner to protect intellectual property inside the models and to reduce deployment costs.
- Aspen Polymers® extends Aspen Plus Dynamics with a complete set of polymer thermodynamics methods and data, polymerization reaction models, and extensions to the equipment models to track polymer properties.
- Aspen Simulation Workbook™ enables easy development of Microsoft Excel®-based user interfaces to Aspen Plus Dynamics, making it easy to deploy your dynamic models to a wider range of users in the plant.
