The department of Particle Technology is leading the SolidSim project which aims at the development of a process modeling and simulation
tool for complex solids processes and unit operations. The project, funded by the German AIF consortium, lasts for 2 years and includes partners from 10 German universities
as well as some 40 advisory industrial partners. A simulation environment and unit operation modules will be developed for various unit operations involving solids, such as
sieving, sifting, drying, crystallization, agglomeration, crushing, filtering, or cyclone process steps.
We found the CAPE-OPEN standard as being highly beneficial and very supportive for the project since it allows the reuse of proven concepts and reduces development effort.
At the same time it enables interaction of the simulation environment with standard CO compliant liquid/gas simulators. The benefit will be that complex processes, involving
solids processing steps as parts of larger liquid/gas processes and vice versa, can be simulated within one simulation environment and therefore allows for parameter
studies and design alternatives for complete processes.
To meet all the special requirements when dealing with solids (e.g. to cover continuous type descriptions of solids properties such as particle size distribution) we had
to extend the CAPE-OPEN standard to meet our requirements and we made a proposal to the SIG Thermo for an extension of the CAPE-OPEN standard towards the inclusion of
distributed properties.

CAPEC-DTU
CAPEC-DTU is a computer-aided process/product engineering center at the Department of Chemical Engineering, the Technical
University of Denmark in Lyngby. CAPEC-DTU’s principal research areas are development and application of computer-aided techniques, methods and tools (software)
in the area of property prediction & modeling, product-process synthesis/design/analysis/operation-control, computer-aided modeling and integration of methods and tools. CAPEC-DTU
was a partner in the Global CAPE-OPEN project and was also one of the founding members of the CO-LaN. Currently, CAPEC-DTU
is one of the associate (academic) members of CO-LaN.
CAPEC-DTU has been working on developing CO-compliant plugs for unit operations and property models through its modeling tools. In this respect, CAPEC-DTU
has developed a computer-aided modeling toolbox called ICAS-MoT (M. Sales-Cruz & R. Gani, "A modeling tool for different stages of the process life", 2003, in
"Dynamic Model Development", Editors: S. P. Asprey & S. Macchietto, Elsevier, The Netherlands, CACE-16, pp 209-238). ICAS-MoT is able to accept external models
and transform them into CO-compliant plugs that can be used through CO-compliant sockets in external simulators and/or external software such as EXCEL. With ICAS-MoT the
user does not need to write any programming code.
In January 2004, CAPEC-DTU will launch its first CO-compliant plug, which is a special property-model plug for the new KT-UNIFAC model (J. W. Kang, J. Abildskov,
R. Gani, J. Cobos, 2002, "Estimation of mixture properties from first and second-order group contributions with UNIFAC models", I&EC Research, 14, pp3260-3273).
This plug is not presently available in any of the commercial simulators. The KT-UNIFAC model is a higher-order group contribution model for estimation of liquid phase
activity coefficients. The property-model plug will also include the new group parameter tables but will require the pure component data for the mixture compounds to be
retrieved from the host software. The KT-UNIFAC plug is currently being tested with AspenPlus.
A second set of CO-compliant plugs will also be released shortly. These are a collection of unit-operation plugs that are being generated automatically through ICAS-MoT
by transferring the model equations obtained in text-format from the original articles where they were published, analyzing them and then generating the CO-complaint plug.
An industrial consortium of member companies (current membership includes 28 companies from Denmark, Europe, North America and Japan) supports research at CAPEC. For more
information about the activities of CAPEC and on the status and availability of CO-compliant plugs and computer-aided modeling tools that can generate them, please visit
