Separating a carbon dioxide/air mixture by absorption in counterflow
Features
– separating a CO2/air mixture by absorption in counterflow
– DURAN glass column with packed bed
– safe operation due to use of water as the solvent and non-hazardous gases
– regeneration of solvent by vacuum
– gas analysis with hand-held measuring unit
Learning objectives/experiments
– investigation of the absorption process when separating gas mixtures in a packed column
– determination of pressure losses in the column
– representation of the absorption process in an operating diagram
– investigation of the variables influencing the effectiveness of absorption
