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.
