Air
The didactic focus of the air subject area is the various methods for treating gaseous media (air pollution control). Most contaminants can be removed from an exhaust airflow by mechanical or thermal processes.
Mechanical waste air purification
The aim of mechanical processes is separation of particles from an exhaust gas flow (dust extraction). The separation of particulate matter in particular is of great importance.
CE 235
Gas cyclone
Removal of solids from raw water using dissolved air flotation.
Thermal waste air purification
Thermal processes are used to remove gaseous contaminants. The exhaust gas should largely be free of dust, which means mechanical cleaning needs to take place initially.
CE 400
Gas absorption
Separating a carbon dioxide/air mixture by absorption in counterflow.
CE 540
Adsorptive air drying
Basic principle of adsorption and desorption.
