Annotation -
Two-semestral course of Chemical Engineering A/B will give to students the knowledge and skills important, e. g., for development of new technological processes in area of industrial R&D, in particular for scale-up from laboratory to industrial process. Basic transport phenomena will be briefly introduced (mass, energy and momentum balances). Selected unit operations (in area of heat exchange, hydrodynamical, separation and particle technology processes as well as chemical reactors). Finally, the methodology for whole process synthesis will be discussed.

Aim of the course -

Students will be able to:

  • to explain principles of selected unit operations in chemical technology processes
  • to carry out approximative design and control calculations of selected unit operations
  • to select an optimal choice of process alternatives using chemical-engineering analysis
