Abstract
It is well known that the column apparatuses operating at full countercurrent flow ensure maximum driving force for mass transfer when equilibrium processes are used. It is also known, from the mass balance, that the ratio between gas and liquid superficial velocity, in case of countercurrent flow, is determined from the initial and end concentrations of the absorbed component in both phases. In many cases, especially in purification of waste gases, when the initial gas concentration is very low and its solubility is high, the necessary calculated liquid superficial velocity is extremely low. The lack of packings able to operate effectively at these conditions requires a division of the packing bed into layers with recirculation of the liquid phase in each of them, i.e., a refusal of the principle of complete countercurrent flow takes place. The paper shows the possibility to use this principle even at extremely low liquid superficial velocity.
