gO:CAPE-OPEN

The gPROMS Object for CAPE-OPEN

The gPROMS® Object for CAPE-OPEN (gO:CAPE-OPEN) is a powerful tool that enables you to execute any gPROMS model within a CAPE-OPEN compliant flowsheeting environment such as Aspentech’s Aspen Plus® and Invensys SimSci’s PRO/II®.

This means that you can build a model of whatever complexity you require using gPROMS ModelBuilder’s state-of-the-art modelling and solution capabilities, and then run it within traditional process flowsheeting tools.

Example

For example, TOTAL implemented a complex three-phase Fischer-Tropsch GTL slurry bed reactor in gPROMS for execution in Invensys SimSci’s PRO/II steady-state flowsheeting package.

With gO:CAPE-OPEN you can build a custom model of a reactor, use gPROMS’s parameter estimation capabilities to determine kinetic constants, optimize geometric aspects, operating conditions and control performance for various feed change scenarios, then use exactly the same model for steady-state simulation within PRO/II.

The gPROMS model executing within the flowsheeting environment can use the environment’s native physical properties, ensuring consistency across applications.

Benefits

This powerful combination of technologies:

  • lets your engineers work in their environment of choice
  • enables you to remain in compliance with corporate software standards
  • helps promote seamless working across different parts of the organisation

while accessing the advanced process modelling power of gPROMS to deliver additional value at every step.

How gO:CAPE-OPEN works: a simple step-by-step guide

You can package and export any gPROMS model to a CAPE-OPEN compliant flowsheeting package.

The resulting object includes all the solvers and support software required for the model’s solution. The gPROMS model is executed just like any other unit operation within the package.

Procedure for deploying a CAPE-OPEN model within a flowsheeting package

Step 1Build a gPROMS model of the reactor or separation unit (for example) in gPROMS ModelBuilder.

Step 2Export the gPROMS model using the ModelBuilder export facility. The model is packaged for export with all the solvers required for solution.

 

 

 

Step 3Import the gPROMS model into the CAPE-OPEN compliant process simulator – for example, Aspen Plus®.

Step 4Perform steady-state process simulation using the gPROMS high-fidelity reactor model within the Aspen Plus® environment.

Licensing

gO:CAPE-OPEN is licensed as a separate PSE product. A gPROMS ModelBuilder licence is required for building the gPROMS model that will execute within the CAPE-OPEN environment.

PSE’s commitment to CAPE-OPEN

PSE is committed to the CAPE-OPEN set of standards and is an Associate Member of the CO-LaN organisation.

PSE has played a major part in defining CAPE-OPEN standards over the years.

More Information

We were able to build a highly-detailed model of reactive absorption that we could then drop straight into an Aspen Plus flowsheet for steady-state analysis of process synthesis.

This gave us the power and ease-of-use of gPROMS while allowing us to comply with corporate software policy.
