The solute migration phenomenon from the gas to the liquid phase occurs when both phases are contacted in the packing of the reverse flow absorption column. This highlights the absorption operation (solvent purification). The regeneration phenomenon is observed on the second column, which is continuously fed. An energy‐saving heat exchanger is placed between the two columns to optimize the power spent on the unit. A second heat exchanger is placed on the absorption side to cool the fluid returning to the head of the column. The third heat exchanger, placed on the regeneration side, allows the solution to be heated in order to be regenerated in column. The use of such a unit allows one to remove COfrom air using monoethanol amine and to recover pure CO2 to capture it.
