GTT Development Partners

GTT has contacts to many scientists all around the world. However, there are some with whom we have especially close and formalized links. These are listed below:

Ex Mente, Pretoria

Ex Mente is a process engineering consulting and systems company. The company was founded in 2001, and is based in Pretoria, South Africa. They supply process engineering solutions through consulting services, deployment of in-house developed software systems, and implementations of off-the-shelf software products.

Lehrstuhl für Werkstoffchemie (Materials Chemistry) at RWTH Aachen

With Materials Chemistry, we have a general co-operation contract on the development of data and methods in the field of technical thermochemistry. We collaborate together on research projects with national and European funding.

Centre for Research in Computational Thermochemistry, CRCT at Ecole Polytechnique de Montreal

With CRCT and the FACT group in Montreal we co-develop our common product FactSage, the Windows™ based successor of ChemSage. We also work together on the development of data as needed in our research and development projects – and by our clients.

Scientific Group Thermodata Europe, SGTE

As a member of SGTE we co-operate with the other members in bi- or multi-lateral projects on the maintenance and development of the SGTE databases. We have also been engaged in the writing and editorial activities of the SGTE Casebook.

VTT Chemical Technology, Helsinki

With our colleagues at VTT we co-develop our common product ChemSheet. We also co-operate on the development of particular applications of ChemSheet both on behalf of particular customers and in international scientific products. A special emphasis in this work is put on the combined application of kinetic and thermodynamical aspects of inorganic processes.

The institute for Energy and Climate Research of Forschungszentrum Jülich (IEK-2)

The institute for Energy and Climate Research, Microstructure and Properties of Materials, of Forschungszentrum Jülich IEK-2 (Institut für Energie- und Klimaforschung,Werkstoffstruktur und -eigenschaften, IEK-2) is our long-term partner in the project HotVeGas on high-temperature coal gasification. We co-operate in the development of the thermodynamic database for the project as well as in the modelling of the viscosity of molten oxides. Furthermore we co-operate in the project VerSi on slagging and fouling in coal fired power plants (see the respective contributions to the 2016 User Meeting).

SMS group, Düsseldorf

With colleagues of the SMS group we co-operate on the development of the Process Simulation toolkit SimuSage.

The Spencer Group, Trumansburg

With the Spencer group, we have started a co-operation on metal related databases. The first product was a Noble Metal database. Today, the Spencer Group Carbide-Nitrode-Boride-Silicide database [SpMCBN] is interesting for users who are interested both in metallic as well as refractory systems since it expands the (metallic) SGTE solutions database to refractory materials.
