Title:
ＣＯ２分離回収装置並びにＣＯ２分離回収装置を備えた石炭ガス化複合発電プラント
Document Type and Number:
Japanese Patent JP5631143
Kind Code:
B2
Abstract:
Provided are CO 2 separation and recovery equipment that yields a higher CO 2 recovery rate, and a coal gasification combined power plant including the CO 2 separation and recovery equipment with high plant efficiency. The CO 2 separation and recovery equipment of the invention, having a CO shift reactor in which a gas containing main components of CO and H 2 O is introduced and converted into CO 2 and H 2 , 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. The steam control valve is controlled by the difference in the molar amount of CO and H 2 O that is calculated from the analysis results of the gas composition analyzer, and the inlet valve and the outlet valve of the CO shift reactor are controlled on the basis of the catalyst tank temperature of the CO shift reactor.
