Mass transfer in a continuous phase as well as the interfacial mass transfer are studied. Multicomponent mass transfer, molecular diffusion, turbulent diffusion and axial dispersion are described. Further the absorption accompanied by chemical reaction is studied, including the definition of interfacial mass transfer modes in dependency on the accompanying reaction kinetics.

After completing the course, student will have more detailed knowledge on physico-chemical phenomena, which play key roles in industrial process design. The subject broadens basic knowledge got in the course on Unit Operations, teaches to understand mass transfer phenomena and givesthe ability to more precisely analyze the phenomena controlling industrial proces capacity.
