PURPOSE: To allow the selective permeation of the gaseous CO2 and steam contained in the air supplied on a primary side to a secondary side by sealing a soln. having high solubility and diffusibility to the gaseous CO2 and the steam between two sheets of thin films having excellent gas permeability and providing a pressure difference between the primary side and the secondary side of the thin films.
CONSTITUTION: The soln. having the excellent solubility and diffusibility to the gaseous CO2 and the steam is sealed between 5 the thin films having the characteristics to allow the high permeation of gases but do not allow the permeation of liquid. The circulating air 3 in the hermetic space is introduced to a supply gas cell 6 segmented by the liquid film 5 of the film module 4. The secondary side of the liquid film 5 is in contact with a permeated gas cell 7 and this cell is maintained under a reduced pressure by a vacuum pump 8. The gaseous CO2 and steam contained in the circulating air 3 introduced into the cell 6 permeate to the cell 7 side while the gas and steam are selectively dissolved and diffused in the liquid film 5 by the pressure difference between both sides of the liquid film 5 as a driving power; thereafter, the gas and steam is taken out as a permeated gas 9 via a vacuum pump 8.
