A method of treating a carbon dioxide-containing gas, comprising providing an inverse J-shaped pipe including a shorter pipe having a first open end, a longer pipe having a second open end, and a connecting portion by which the shorter and longer pipes are connected with each other, such that the first and second open ends represent opposite ends of the inverse J-shaped pipe; positioning the inverse J-shaped pipe under the sea such. that the shorter and longer pipes extend downward from the connecting portion; injecting the carbon dioxide-containing gas from a portion of the shorter pipe adjacent to the first open end into the shorter pipe so that seawater is forced to enter the first open end, to flow upward together with the carbon dioxide-containing gas through the shorter pipe, to flow downward through the longer pipe and to be discharged from the second open end, with the carbon dioxide being dissolved in the seawater during the passage of the carbon dioxide-containing gas through the shorter pipe; and extracting an indissoluble gas, which remains undissolved in the seawater during the passage of the carbon dioxide-containing gas through the shorter pipe, from the seawater in the connecting portion, so that the seawater discharged from the second open end contains carbon dioxide dissolved therein. |
