PURPOSE:To well dissolve CO2 discharged from an iron manufacturing process in seawater in the depths of the sea, to preserve the CO2 and to prevent the warming of the earth by blowing the CO2 into the depths of the sea. CONSTITUTION:Gas discharged from an iron manufacturing process contains CO2 and CO in large quantities. When the CO2 and CO are blown into seawater, they are blown as CO2 into the depths of the sea after the CO is converted into CO2 by a water gas shift reaction optionally in the presence of an iron oxide iron chromium catalyst, etc. The blown CO2 attains to the critical pressure or exceeds the pressure and dissolves in the seawater by the increased solubility. Since the seawater in the depths of the sea moves hardly toward the surface of the sea, the CO2 is preserved in the depths of the sea and the warming of the earth is prevented. |
