Aalto – Chemical/Physical separations

AALTO University has excellent lab scale facilities to carry out chemical/physical separation processes for high-level academic reseach. Evaporation (e.g. falling film), extraction, distillation and crystallisation (up to 25 l scale) are routinely carried out in research groups.  

In addition Chemical Engineering Reseach Group has developed software and experimental setups for several new unit models that combine both reaction step and separation step in an efficient way (e.g. reactive distillation). Research group has built several laboratory equipments for vapor/liquid and liquid/liquid measurements that are applicable in wide temperature, pressure and concentration area as accurete phase equilibrium (VLE/LLE) models are essential in the design of separation processes. Research started with applications in hydrocarbon and chemical systems, recent activities cover gas solubility in pulping liquors.

Efficient and environmentally friendly separation processes are essential in biorefinery. Knudsen effusion apparatus is built for measuring vapor pressures of pure organic compounds and their mixtures. The apparatus has been utilized for research on pyrolysis oils as well as on recycling of ionic liquids in biorefinery processes. The groups has also expertice in separation of commercially useful sugars from the biorefinery by-product by chromatography process.
