The feasibility study of a carbon capture system: the case study of FEA’s Waste to Energy plant

This paper presents a feasibility case study on the Carbon Capture and Storage (CCS) process development in the Waste to Energy plant of FEA. The idea to implement a new section to reduce the plant’s GHG emissions comes from the future inclusion of the waste to energy plant in the European Emission trading system (EU ETS) and from the probable increase of EU carbon permits in sight of the EU’s roadmap for the climate neutrality within the 2050. Among the possible technologies available, the process design selected includes the CO2 absorption with potassium carbonate, the compression and liquefaction of CO2 and geological storage in a depleted oil and gas reserve. The purpose of this work is to evaluate the magnitude of the mass flows, the utilities demand and the possible heat recovers to obtain the overall cost, in function of the CO2 captured.
