NOVELTY - A floating material-type power generating plant (11) consists of floating material (10) floated in sea, liquefied natural gas (LNG) tank which stores LNG (F1), heat exchanger which heats the liquefied natural gas, electric power generation system which produces electric power using natural gas obtained by heating liquefied natural gas, carbon dioxide recovery apparatus which recovers carbon dioxide contained in combustion exhaust gas discharged from the electric power generation system, and carbon dioxide discharge portion (50) which discharge the carbon dioxide into the ocean.    USE - Floating material-type power generating plant (claimed).    ADVANTAGE - The carbon dioxide is efficiently processed using the floating material-type power generating plant, by simple method.    DETAILED DESCRIPTION - A floating material-type power generating plant consists of floating material floated in sea, liquefied natural gas (LNG) tank which stores LNG, heat exchanger which heats the liquefied natural gas supplied from the LNG tank, electric power generation system which produces electric power using natural gas obtained by heating liquefied natural gas in the heat exchanger as fuel, carbon dioxide recovery apparatus which recovers carbon dioxide contained in combustion exhaust gas discharged from the electric power generation system, and carbon dioxide discharge portion which discharge the carbon dioxide recovered by the carbon dioxide recovery apparatus to the ocean. The LNG tank, heat exchanger, electric power generation system, carbon dioxide recovery apparatus and carbon dioxide discharge portion are installed in the floating material. The liquefied natural gas is heated, natural gas is produced by performing heat exchange between the carbon dioxide recovered by the carbon dioxide recovery apparatus and the liquefied natural gas supplied from the LNG tank in the heat exchanger, the carbon dioxide is cooled, liquefied, and liquefied carbon dioxide in the heat exchanger is discharged to the ocean from the carbon dioxide discharge portion.
