Chemical processes and modelling

Optimize your processes in silico

If you face problems that can be solved through process chemistry and modelling, VTT can help. We have over 20 years’ experience in developing process models and chemical system models based on thermodynamic principles. We can help you to develop and optimise your chemical conversion and product separation processes. The benefits you can realise include savings in raw materials and energy, improved runnability and better control of measured process parameters. We can introduce new process chemistry alternatives, and also help with the development of new products and processes.

Computational chemistry

VTT solves complex industrial problems by combining experimental research and rigorous theoretical modelling. Data flows either from laboratory and analytical practices, or directly from pilot and process measurement, into our internationally recognized process simulation software ChemSheet® and KilnSimu for computational research.
Recently, VTT developed a Constrained Free Energy (CFE) technique to include essential new features in thermodynamic multi-phase process simulation. This technique has been put into commercial practice in over 15 countries.

Techno-economic assessments of process concepts

Chemical processes are designed and developed for different reasons. Sometimes it’s to select the most profitable alternative among process concepts, and sometimes changes in one unit process have mill level effects that need to be analysed. In other cases, the goal is simply to estimate raw material and energy costs of a process. To meet these challenges, VTT uses state-of-the-art process simulation models as the basis of techno-economic assessments. Our tools range from spreadsheet applications to high fidelity process simulators.  

Fractionation and product recovery

VTT has strong expertise in characterising and processing many different kinds of biomass. The fractionation technologies that we have developed include chemical, catalytic, enzymatic and thermochemical processes. We also develop the technology required to recover, purify and further process fractionated bio-based components—first in the laboratory, then in onsite pilot-scale facilities.
Product recovery is another essential part of any chemical process development and often has a significant economic impact on the value chain. In this area VTT has experience in distillation, solid-liquid and liquid-liquid extraction, as well as phase equilibrium measurement.

Catalytic processes

Catalytic processes help to transform raw materials into valuable products. For example, biomass and biomass-based materials can replace materials made from petrochemicals. At VTT we make use of state-of-the-art experimental and modelling facilities to develop catalytic processes in the laboratory, bench or in pilots, together with versatile analytical services.
