FIELD: power industry.
SUBSTANCE: invention relates to the device for carbon dioxide extraction. In this case the device for extraction, in essence, contains an absorption unit for absorption of combustion gas of the power plant consuming the fossil fuel, a desorption unit and a heat exchanger. The heat exchanger from the first side of supply is connected through the return line of the inlet side with the desorption unit, and from the branch it is connected through the return line of the branch side to the absorption unit. The heat exchanger from the second side of supply is connected through the supply line of the inlet side with the desorption unit, and from the branch it is connected through the supply line of the branch side to the absorption unit. Besides, the first bypass line is provisioned, by means of which the return line of the inlet side is connected to the supply line of the branch side, therefore, at least, almost closed first contour with desorption unit is formed, and the second bypass line by means of which the supply line of the inlet side is connected to the return line of the branch side in such a way that at least almost closed second contour with absorption unit is formed.
EFFECT: carbon dioxide extraction provided.
