ABSTRACT:
The present invention provides a simple and efficient means for dissolving carbon dioxide gas discharged from sources such as thermoelectric power plants into the seawater and for isolating it at deep sea level. The means comprises an inverted U-shaped gas lift 1 having a shorter gas lift dissolving pipe 2 and a longer descending pipe 3 being connected with each other at the top, said gas lift dissolving pipe 2 is held at shallow sea level, and the lower end of the descending pipe 3 is opened at deep sea level. When carbon dioxide gas is injected in from the lower end of the gas lift dissolving pipe 2, the seawater is introduced from the lower end of the dissolving pipe by gas lift action of the carbon dioxide gas in the dissolving pipe 2, and the carbon dioxide is completely dissolved into the seawater until it reaches the upper end of the dissolving pipe. With its density increased due to dissolving of the carbon dioxide, the seawater is moved down by gravity to deep sea level through the descending pipe 3 and carbon dioxide is isolated at deep sea level.
