Many technological solutions were proposed for CO2 capture in the last years. Most of them are characterized by high costs in terms of energy consumptions, and consequently higher fossil fuel use and higher economical costs. High temperature fuel cells are technological solutions currently developed for energy production with low environmental impact. In Terni CIRIAF labs cylindrical geometry small size MCFC prototypes were built and tested with good energy production and lifetime performances. In the present work, the innovative application for MCFC is proposed: an innovative configuration for CO2 capture/separation is investigated. The plant scheme is based on a reformer and a cylindrical MCFC. MCFC are most suitable solutions because CO2 is used in their operating cycle. An analysis in terms of energy consumption/kgCO2 captured is made by coupling the proposed configuration with a gas turbine plant. The proposed configuration is characterized by a theoretical energy consumption of about 500 kJ/kgCO2, which is quite lower than actual sequestration technologies. An experimental campaign is going to be planned scheduled to verify theoretical findings.

Abstract
Many technological solutions were proposed for CO2 capture in the last years. Most of them are characterized by high costs in terms of energy consumptions, and consequently higher fossil fuel use and higher economical costs. High temperature fuel cells are technological solutions currently developed for energy production with low environmental impact. In Terni CIRIAF labs cylindrical geometry small size MCFC prototypes were built and tested with good energy production and lifetime performances. In the present work, the innovative application for MCFC is proposed: an innovative configuration for CO2 capture/separation is investigated. The plant scheme is based on a reformer and a cylindrical MCFC. MCFC are most suitable solutions because CO2 is used in their operating cycle. An analysis in terms of energy consumption/kgCO2 captured is made by coupling the proposed configuration with a gas turbine plant. The proposed configuration is characterized by a theoretical energy consumption of about 500 kJ/kgCO2, which is quite lower than actual sequestration technologies. An experimental campaign is going to be planned scheduled to verify theoretical findings.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
