Up to now, it is well known that computer-aided tools play a vital role in the modelling/design/analysis/control of chemical processes and products thus manufacture. As these tools may come from different sources and disciplines, how can they be used efficiently for the design/analysis of specific process-product? The CAPE-OPEN interfaces, in this case, make the possible integration of the needed computational tools.
The objective of this presentation is to highlight the application of computer-aided modelling tools for generation and use of modelling objects in CAPE-OPEN compliant process simulators. This presentation will highlight the use of external modelling objects for unit operation models as well as thermodynamic property models. What we need are the following:
• A process simulator with a CAPE-OPEN socket (e.g. ProSim Plus).
• A CAPE-OPEN unit/property methods wrapper (link) that is able to receive an external model object from an external source.
• The model object representing any model (unit operation or thermo) generated for a computer-aided modelling tool for model translation, analysis and solution (ICAS-MoT).
The advantage of using ICAS-MoT is that it is possible to transfer the model equations representing any new unit operation/thermo into a COM-object that can be used in some simulation engines (Icassim and Dynsim available within ICAS software), external software (i.e. EXCEL) or external simulators (ProSim, etc) with a well defined interface without the user having to write any programming code. ICAS-MoT also carries out the analysis of degrees of freedom, determination of the structure of the equation system, index analysis, partitioning and ordering of the model equations and numerical analysis; and the solution of the model analyzed in the previous step, and thereby, producing customized simulators for a particular process.
The presentation will highlight the application of CAPE-OPEN interfaces for a model generated and tested in ICAS-MoT and then its equivalent COM-object is created. This COM-object is then wrapped by a generic unit-wrapper and plugged into the CAPE-OPEN socket of ProSim Plus (CAPE-OPEN compliant process simulator). It will also highlight the synergy between ICAS-MoT and Simulis (from ProSim) through established generic CAPE-OPEN link.
