The research at the division of Transport Phenomena is carried out in four different research groups: crystallization, protein crystallization, drying technology, and separation of rare earth metals.
Separation of rare earth metals
The research aims to develop new processes for the selective separation of rare earth metals from leach solutions, preferentially from the mining industry. The work is performed in cooperation between the Chemistry Department and the Chemical Engineering and Technology Department at KTH and IVL the Swedish Environmental Research Institute. Three main techniques are being investigated; precipitation, selective chromatographic separations and liquid emulsion extraction.
In the crystallization group, there are three areas of research:
Crystallization of organic fine- and speciality chemicals
The purpose of our work in this area is to increase understanding of different aspects of the crystallization process, e.g. polymorphism, agglomeration and the influence of various process parameters.
Work in this area is mainly focused on solving various difficulties, such as creating effective mixing.
Here, we study models of different aspects of the crystallization process, such as kinetics and product size distribution.
All our projects are carried out in close cooperation with the chemical and pharmaceutical industry.
In the Drying & Process Technology group, there are three areas of research:
Work in this area is mainly focused on heat and mass transfer in single or multicomponent systems, drying of foodstuffs, evaporation and modelling and simulation of drying processes.
Removal of Heavy Metals by Biosorption
The purpose of our work in this area is to develop a treatment system for natural and wastewaters to remove heavy metals using chitosan as adsorbent.
Processing of Natural Products
Here, we develop processes for the manufacture of natural products, for instance, the recovery of a non-edible oil from Neem seeds for biodiesel production.
All our projects are carried out in close cooperation with academic institutions in Latin America.
