  17. CONCLUSIONS • In the process investigated, it is possible to raise CO2 concentration from 12 vol.% to over 95 vol.%, with a virtually total recovery. • The experiments fully corroborate the preliminary theoretical conclusions and reveal the potential of such a technique for efficiently removing carbon dioxide from flue gas streams. • The study has provided a wealth of data that show the principal directions in which further studies should proceed. 8th International Scientific Conference on Energy and Climate Change, 7-9 October 2015, Athens
