    摘要: A CO2 recovery device includes: a CO2 absorption unit for absorbing CO2 in a CO2-containing flue gas, by a CO2 absorbent; a washing unit for cooling a CO2-removed flue gas and recovering the accompanying CO2 absorbent; a circulation line for directly circulating wash water; an extraction line for extracting a part of the wash water containing the CO2 absorbent as an extracted fluid; a first gas-liquid separation unit for separating a gas component from the extracted fluid; a concentration unit for concentrating the CO2 absorbent contained in the extracted fluid and separating the gas component; a concentrated fluid return line through which a concentrated fluid returns to the CO2 absorption unit provided below the washing unit; and a gas inlet line through which the separated gas component is introduced into an absorber.

    摘要: There is provided a large-sized reboiler that can achieve space saving and reduction in plant cost. Specifically, there is provided a large-sized reboiler comprising a vessel of which a liquid is supplied from a lower part and a vaporized gas is discharged from an upper part; and a heat transfer tube group arranged in such a manner that a void penetrating in the up-and-down direction is formed in the vessel, wherein a maximum length of a cross-sectional figure of a flow path for the liquid exceeds 2 m, and the void occupies 5 to 10% of an area of the cross-sectional figure of the flow path.
