11:15 | First principles PRocess concepts for the conversion of complex MixturEs (PR1ME) as CAPE OPEN tool: challenges and opportunities | Cesar Pernalete, University of Ghent


Microkinetic modelling of chemical reactions represents an innovative approach to comprehensively account for all elementary steps involved in the considered transformations, leading to a thorough understanding of the underlying reaction mechanism. The Single-Event MicroKinetics (SEMK) variant enables the application of such a fundamental methodology towards complex mixtures, in which transformations occur through a limited number of reaction families. SEMK finds practical application in simulating processes with vast reaction networks, such as hydrocracking, hydrotreating and catalytic cracking, originally mainly in the context of fossil resources [1,2], at present also in the framework of renewable and circular feedstocks [3,4]. When dealing with complex mixtures, such as fossil hydrocarbon mixtures, renewables, and plastics-derived oils, the exact molecular composition is typically unknown, posing a challenge in applying the SEMK methodology to reactive processes involving these feeds. To overcome this limitation, molecular reconstruction (MR) techniques have been developed to determine molecular representations of such mixtures based on readily measured bulk properties  [5]. The Laboratory for Chemical Technology at Ghent University, Belgium, has developed two software modules to implement the SEMK and MR methodologies. PR1ME is a simulation framework that seamlessly integrates the SEMK and MR modules, presenting a powerful approach to innovative hydroprocessessing [6]. Its implementation within commercial process simulators is currently under exploration, and it holds the promise of allowing users to probe the reactive section of a specific process and facilitate seamless integration with upstream and downstream unit operations. Additionally, being a plug-and-play software module in process simulators, PR1ME empowers users to conduct plant-wide studies with a strong fundamental basis across different simulation platforms. In this presentation, we introduce the architecture of PR1ME as a simulation framework and explore various approaches to make it compatible with plant-wide simulation platforms using the CAPE OPEN standards. By adopting CAPE OPEN standards, PR1ME aims to enhance collaboration and knowledge exchange within the chemical engineering community, ensuring transparency and interoperability. The compatibility with different simulation platforms is being investigated to further expand its usability, making PR1ME a potential valuable tool for advancing innovative chemical processes in a sustainable and efficient manner.

11:40 | System modelling of methanol reformed fuel cell system with integration of Python Unit Operations | Malthe Linquist, Blue World Technologies


Blue World Technologies needed to create a process model to investigate the efficiency and power output of a fuel cell system in which the methanol is reformed. The reformer is an equipment that is inherently hard to model. Using the generic unit operations of the COUSCOUS library integrated in COFE, the exit composition and the energy needed for the process were not estimated as needed. Therefore, Blue World Technologies created a python code to simulate the reformation process. The code contains the reaction kinetics and calculates the energy needed for the reaction to occur. This python code was then integrated in a COFE flowsheet via the CAPE-OPEN Python unit operation provided by AmsterCHEM.

14:10 | Developing a unit operation model for membrane based subsea gas separation in the COMPMEM project using CAPE-OPEN COBIA | Olaf Trygve Berglihn, SINTEF

Remote presentation


The COMPMEM project targeted the small industrial scale testing and qualification of a membrane process for sub-sea CO2 separation and reinjection. The pilot scale process was built and operated at SINTEF’s facilities in Trondheim, Norway. Using the results of the pilot tests a counter-current membrane separation model was developed in FORTRAN with a standard C-interface, and this model was incorporated into a CAPE-OPEN PMC written in C++ using the CAPE-OPEN COBIA library and tools. During the development of the PMC, some issues were encountered due to deviations in how simulator vendors have interpreted the CAPE-OPEN standard for array parameters and the definition of enthalpy derivatives with respect to mole numbers. The PMC was successfully deployed in multiple CAPE-OPEN compliant simulators, leveraging COBIA’s built in and seamless interoperability layer for COM-based implementations. The COMPMEM project was funded by GASSNOVA in the “CLIMIT DEMO” programme with SINTEF, Total, CCP (BP, Chevron, Petrobras), Equinor, Pertamina, and Aker Carbon Capture (coodinator) as partners.

14:35 | Process Modeling in Dymola | Claas Heckel, 3DS

Remote presentation


His presentation brings together several aspects of interest to CO-LaN, to the CAPE-OPEN community and to DYMOLA users. Dymola stands now as a new Process Modelling Environment featuring CAPE-OPEN support, here through a CAPE-OPEN thermodynamic socket. This socket has been implemented using COBIA, the CAPE-OPEN specific middleware developed by CO-LaN. Conclusive tests have also been carried out on a Linux platform, incidently proving the multi-platform capability offered by COBIA.

Dymola is a development and simulation environment based on the Modelica modeling language. It offers an object-oriented, acausal modeling approach that is well suited for modeling cyber physical systems.
For the dynamic simulation of system models in the field of process engineering, the use of accurate material data can be essential. In order to meet this requirement and to give the user maximum flexibility in the choice of thermodynamics and material property models, a CAPE-OPEN interface for Dymola has been developed.
The CAPE-OPEN interface allows for a standardized and seamless integration of existing thermodynamics and fluid property packages into complex system simulations. This unlocks new possibilities for research and industrial applications in the field of process modeling.
In this presentation the architecture of the interface is introduced and a few examples and possible applications made accessible by Dymola are presented.

10:20 | Potential of New DEXPI standards to support better data integration with process simulation | David Cameron, University of Oslo

Remote presentation


The recently developed Process package for the DEXPI standard, also known as DEXPI+, provides a modelling language for representing the engineering information and requirements used in early-phase, process, design. These activities have been poorly supported by standards, so that Process Flow Diagrams are often shallow drawings, without linkage to the plant design. Similarly simulation data and stream tables are managed using legacy tools and spreadsheets. DEXPI+ provides a framework for organizing this early phase data so that it can be linked to plant design and used for operational optimization. The data model deliberately builds on concepts from CAPE-OPEN, and we believe that the model can support modified CAPE-OPEN interfaces that allow exchange of simulation set-up and results in a programmatic, vendor-neutral work. This talk will present DEXPI+ in this context and sketch some ways that it can support automation of simulation and process optimisation.

Carbon Capture and Storage (CCS) is gaining increased attraction as a method to reduce atmospheric CO2 emissions. Different methods exist to capture the CO2 from highly concentrated point sources, like cement and power plants, as well as large plants for capturing CO2 directly from atmospheric air are under construction. None of the methods will produce a 100% pure CO2 stream so the question is which impact different impurities might have, not only for the capturing processes but also for the downstream processes like cooling, liquefaction, transportation, and injection?

The routines for calling calculations of thermodynamic properties of CO2 mixtures have successfully been integrated into a MATLAB model (with great help and support from AmsterCHEM) and applied to help to answer above question. Main conclusions and experiences from implementing and using the code will be presented.

12:00 | Why and how CAPE-OPEN technology can help us to enable reliable modelling of Carbon Capture, Transport & Storage (CCS) systems? | Eduardo Luna-Ortiz, Pace CCS Ltd.


To take advantage of economies of scale, the nascent CCS industry is considering developing projects under a ‘cluster’ model, where many industrial sources will dispose their CO2 to a common transport and storage infrastructure. The operator of the transport/storage system will manage the operation of whole network, but it will not be able to manage the (CO2 capture) operation of each emitter. This is a challenging setup. Any changes on the emitters side will have an impact into the operation and integrity of the network and the storage. The operator should be able to understand how the system reacts to those changes. To achieve this, an integrated model of the whole asset (surface facilities as well as subsurface stores) will become a crucial tool to simulate and optimize the performance of the CCS hub.

In this contribution, we will discuss the current state of modelling practices in the nascent CCS industry (most of them a legacy from the oil & gas industry), the pitfalls of such approaches and the justification to use CAPE-OPEN technology to enable more consistent designs (as well as the challenges that we will still encounter).

12:30 | Lunch

13:30 | Training (On demand): How to easily develop a CAPE-OPEN Process Modelling Component and use a CAPE-OPEN Process Modelling Component in a process simulator


You will create a CAPE-OPEN Unit Operation in MATLAB, using a software from AmsterCHEM: MATLAB CAPE-OPEN Unit Operation. Without having to change anything to the Unit Operation, you will use it in the same flowsheet set up in several commercial process simulators, including ProSimPlus from ProSim, Aspen Plus® from AspenTech® and AVEVA™ PRO/II™ Simulation. The textual model of the CAPE-OPEN Unit Operation, as well as the flowsheets in each process simulator, are provided.

General concepts like ports, parameters, access to thermodynamic calculations will be covered by the course. These concepts will enable you to develop the simple MATLAB calculation script representing the model of the Unit Operation. The script accesses the properties of feed streams, defines calculations to be performed and sets properties of the outletstreams. 

No in-depth knowledge of any of the process simulators used, or of MATLAB is necessary to benefit from this course. At the end of the course, you will have experienced how the underlying CAPE-OPEN technology, present in all the software tools used, simplifies the workflow for users of process simulation tools.
