Supervisor:

Department of Process Engineering

Synopsis:

This course is focused on unit operations that might occur in heterogeneous mixed systems. It describes these operations and equipment design of the most common equipments such as agitated vessels, static mixers, in-line mixers, columns and fluidization equipments. The course enlarges knowledge obtained in the basic course of the study branch "Process engineering? or creates the basis for students studying various specializations. The study plan will be tailored by the choice from the following general offer to meet the requirements of the dissertation topic.
