Annotation -
The course focuses on 1) more detail chemical-engineering description of several industrial mass-transfer driven separation processes 2) description of the diffusion processes in the homogenous media and in the vicinity of the interface. Effect of the homogenous and heterogenous chemical reaction accompanying the diffusion processes is also described.

Aim of the course -

Students will be able to describe procesess in the view of physico-chemical phenomena. They will be able to calculate the parameters of unit operations in industrial scale. Will get wider knowledge of the phenomena mentioned in Chemical Engineering I and II.
