  • Gas Absorption Operations - Separation Processes

    We will be concerned primarily with counter-current gas absorption. As shown in the Figure below, the gas flows upwards while the liquid flow downwards. Inside the column where there is vapour-liquid contact, mass transfer by absorption occurs, i.e. there is a transfer of solute(s) from the gas phase to the liquid phase. [ Back on Top ]
