Abstract
Provided are CO2 separation and recovery equipment that yields a higher CO2 recovery rate, and a coal gasification combined power plant including the CO2 separation and recovery equipment with high plant efficiency. The CO2 separation and recovery equipment, has a CO shift reactor in which a gas containing as its main components of CO and H2O is introduced and converted into CO2 and H2, and includes: an inlet valve that is provided on the inlet side of the CO shift reactor; an outlet valve that is provided on the outlet side of the CO shift reactor; a steam control valve for applying high-temperature steam to a foregoing part of the inlet valve; and a gas composition analyzer that senses a gas composition of a stream flowing into the CO shift reactor.
