Abstract
Waste carbon dioxide gas discharged in large quantities from stationary gas generating facilities such as thermal power plants, is dissolved in sea water and isolated deep in the sea to prevent global warming. A vessel is installed in the sea or at the water surface or in the vicinity thereof. A pipe forming a short leg is open at a lower end, functions as a dissolving pipe, and is equipped with a device for blowing a water-soluble gas. A pipe forming a long leg is open at a lower end portion and functions as a sinking pipe. The pipe forming a short leg and the pipe forming a long leg are connected through the vessel, and undissolved gas is diffused into the atmosphere or into the sea from the liquid surface within the vessel.
