Abstract

Molten Carbonate Fuel Cells (MCFCs) can be proposed as an interesting CCS solution taking account that MCFC cathode fed with air containing CO2can return fresh air. This peculiar property is related to the electrochemical reactions that take place inside MCFCs and allow CO2and O2 can move from the cathode to the anode selectively. So MCFCs can be used, for example, to reduce the CO2emissions per kWh of a conventional power plant by feeding its exhaust to MCFC cathode: the CO2is concentrated at the anodic side and then more easily separated from this stream characterised by lower flow-rate and higher CO2concentration. Moreover, additional power is produced during the separation process. Is possible then to think about the retrofitting of existing traditional power plants integrated with MCFC used to concentrate CO2and separate it more efficiently. In order to verify the actual possibility of real integration and the real energy consumptions the study has been referred to a separation plant with MCFC-oxyfuel. Aim of this work is to demonstrate the feasibility of this system according to different operating conditions of exhausted gas of the power plant. By calculating primary energy consumption for CO2avoided, MCFC capture system can be compared to the conventional systems. A theoretical analysis based on modelling activity and experimental data are presented.
