Title:
GAS TURBINE PLANT
Document Type and Number:
WIPO Patent Application WO/2021/015260
Kind Code:
A1
Abstract:
This gas turbine plant is provided with: a gas turbine; an exhaust line; a waste heat recovery boiler that generates steam from the heat of exhaust gas and guides the exhaust gas to the exhaust line; a carbon dioxide recovery device that recovers carbon dioxide included in the exhaust gas; a heat exchanger that is disposed between the waste heat recovery boiler and the carbon dioxide recovery device and that cools the exhaust gas to a predetermined temperature; and a circulation line that branches from a position between the carbon dioxide recovery device and the heat exchanger and is connected to an entrance of the gas turbine. The carbon dioxide recovery device comprises an absorption tower that absorbs carbon dioxide included in the exhaust gas by bringing the exhaust gas at the predetermined temperature and an absorbing liquid into contact with one another. The heat exchanger is formed from a material with greater corrosion resistance than a material from which the waste heat recovery boiler is formed.
