Aspen Online Deployment™

Deploying process models to improve plant operations

Aspen Online Deployment enables the use of models in plant operations for a wide range of real-time process monitoring, soft sensor, and operator advisory applications. Models are executed on a periodic schedule using conditioned on-line plant measurements. Model predictions are published to the historian to populate operator displays, or tracked for trend analysis.

Features

Integrated with AspenTech’s aspenONE Process Engineering applications: Ensures seamless compatibility with the Aspen Plus®, Aspen HYSYS®, and Aspen Custom Modeler® families of products.
Automatic periodic execution: Executes steady-state process models without any programming.
Built-in data conditioning and steady-state detection: Ensures model predictions are based on reasonable inputs.
Easy links to model variables: Uses a simple copy/paste workflow to create links to process model variables. The variables can also be imported directly from Aspen Simulation Workbook™.
Easy links to plant data tags: Browse tags from any OPC, CIM-IO, or Aspen Process DataTM server; create links by dragging and dropping tags onto model variables.
Compatible with Aspen Process Data clients: Integrates with products such as Aspen Process Explorer and Aspen Web.21; enables customers to monitor and analyze online model predictions and from the desktop or custom web pages.
Aspen Production Control Web Server: Monitors the application through a prepackaged web interface.

Related Products

Aspen Online Deployment is compatible with the following products:
Aspen Plus®, including Aspen Polymers Plus®, Aspen RateSep™, and Aspen Dynamics® (all simulation modes).
Aspen HYSYS®, including Aspen HYSYS Upstream™ and Aspen REFSYS® options.
Aspen Custom Modeler® and related products including Aspen ADSIM™ and Aspen Chromatography®. All run modes are supported.
Aspen Online Deployment can import variable definitions exported from Aspen Simulation Workbook, enabling smooth transition from on-demand online applications to real-time online applications.

Benefits

Customers have reported significant benefits from deploying models into operations using real-time systems including:
$20M annual savings in upstream operations through online monitoring
$4M annual savings in an exchanger fouling monitoring application for a VDU
$1M annual energy savings and $1M in additional capacity resulting from an on-line crude preheat performance monitoring application
10% profit increase from an FCC monitoring application
Months of saved labor by avoiding the need to use Visual Basic programs to accomplish these types of results
