Abstract:
1. A carbon dioxide separation recovery system comprising: an absorption tower that allows carbon dioxide contained in a combustion exhaust gas to be absorbed to an absorption liquid; a regeneration tower that is supplied with the absorption liquid having carbon dioxide absorbed, from the absorption tower, discharges a carbon dioxide gas that contains steam from the absorption liquid, regenerates the absorption liquid, and discharges an exhaust gas that contains steam and the discharged carbon dioxide gas; a regenerative heat exchanger that is provided between the absorption tower and the regeneration tower, and heats the absorption liquid, which has absorbed carbon dioxide and is supplied to the regeneration tower from the absorption tower, by using the regenerated absorption liquid, which is supplied to the absorption tower from the regeneration tower, as a heat source; a reboiler that is connected to the regeneration tower and heats the absorption liquid of the regeneration tower, using a heating medium; and a measuring device that measures an amount of heat supplied to the absorption liquid from the heating medium, wherein the measuring device includes a cooler that cools the heating medium discharged from the reboiler, and obtains the amount of heat that is supplied to the absorption liquid from the heating medium by subtracting an amount of heat that is retained by the heating medium cooled by the cooler and an amount of heat, which is removed from the heating medium in the cooler, from an amount of heat that is retained by the heating medium supplied to the reboiler.
