aspenONE® Advanced Process Control for Polymers
Enables consistent and stable manufacturing performance; maximizes operational agility and profitability
aspenONE Advanced Process Control for Polymers enables manufacturers to optimize
manufacturing operations, providing greater agility in responding to market demands.
The solution set enables process and product consistency by minimizing variability
and facilitating consistent manufacturing execution. Companies deploying aspenONE
Advanced Process Control for Polymers realize significant improvements in performance
and profitability. Benefits include up to a 10% increase in throughput, 1-3% increase
in yield, and 50% or greater reduction in in-grade product quality variability,
transition times, and off-spec material losses. Additional benefits include standardization
of processes and best practices, leading to higher operational stability and reduced
maintenance requirements.
aspenONE Advanced Process Control forPolymers
is comprised of the following:
- Aspen Nonlinear Controller is the fully nonlinear model-based controller
engine used to keep the process at optimally determined setpoints and to optimally
transition from one operating region to another. The easy-to-use graphical interface
allows operators to visualize all key process operations in a single screen and
efficiently manage and interact with the controller and transition manager.
- Aspen Process Statistical Analyzer is an advanced modeling and
data analysis tool that provides an environment for building and managing polymers
controller projects. The workflow-oriented interface allows for building, analyzing,
and deploying controllers within a single environment.
- Aspen Inferential Qualities enables modeling and implementation
of inferred product qualities, and makes it possible to implement linear or non-linear
inferential sensors on-line. Inferential sensors are fundamental elements of many
advanced process control systems. Key parameters (such as naphtha 95% point and
polymer melt index) are often inferred rather than directly measured.
- Aspen Process Sequencer integrates operator actions with the advanced
control system to help plant personnel implement complex recipe transition strategies.
The solution provides for automation of best practices while reducing transition
times and off-spec material losses. Aspen Process Sequencer includes recipe management
features to create and store operating parameter sets for each product manufactured.
It also provides an automated way to download a selected recipe into the control
device to change the production line for a new product, while managing the complex
interdependencies between various operating parameters.
