APPARATUS AND METHOD FOR CAPTURING CARBON DIOXIDE FROM COMBUSTION EXHAUST GAS AND GENERATING ELECTRIC ENERGY BY MEANS OF MCFC SYSTEMS

摘要

An apparatus (1) for capturing carbon dioxide (CO2) from combustion exhaust gas and generating electrical energy by means of MCFC systems, which includes : at least one molten carbonate fuel cell (4), having a cathodic compartment (5) and an anodic compartment (6); a supply line (7) for supplying exhaust gas to the cathodic compartment; a CO2 separation system (8), connected to an outlet of the anodic compartment (6) and designed to separate CO2 from a flow of anodic gas coming from the anodic compartment; and a heat-exchange assembly (11) set along the exhaust gas supply line (7) for controlling, in synergism with a cathodic recirculation line (21), the temperature of the oxidizing gas supplied to the cathodic compartment (5).
