INTEGRATED PROCESS AND SYSTEM FOR CARBON DIOXIDE EMISSION CAPTURE

摘要

A method and system are provided for reducing carbon dioxide (C02) emissions from flue gases. The method may include: transmitting the flue gases to a first reactor (2) where the flue gases may be placed in contact with a C02 absorbent; recovering the carbonated absorbent from the first reactor (2) and transmitting the carbonated absorbent to a combined fuel reactor and calciner (13); oxidizing a fuel in the second reactor (13) using metal oxide as an oxygen carrier and calcinating the absorbent during the fuel oxidation to remove C02 from the absorbent; recovering the reduced metal from the fuel reactor (13) and transmitting the metal an air reactor (17), which is supplied by air to permit re-oxidation of the metal; and recovering the absorbent from the fuel reactor (13) and transmitting the absorbent to the first reactor (2) to absorb additional C02 from the treated flue gases.
