Abstract: Method and system to capture target gases from all kind of point-sources, as well as from ambient air and surface waters, sediments or soils by advantage of large differences in Henrys law constants. For gas dissolution in water the constants favor dissolution of e.g. CO2 compared to the main constituents of flue gases like N2 and O2. The main principle is to dissolve the gases—release of the non-dissolved part stripping the liquid for the dissolved gases, which are enriched in target gas. Further steps can be used to reach a predetermined level of target gas concentration.
