Valutazione tecnico-economica di schemi di cogassificazione di carbone e biomasse a ciclo combinato (IGCC) con cattura di CO2

This paper reports the results of process simulations of an integrated gasification combined cycle (IGCC) of about 330 MWe in which the traditional coal and pet-coke feed is partially replaced by biomass (dried olive husk and grape seed powder). The effect of the concentration of biomass on the composition of the synthesis gas, on the distribution of energy generated in the gas turbine and in the steam turbine, and on the gross cost of energy was assessed. Also preliminary assessment of a pre-combustion CO2 capture section based on WGS reactors and selective membranes was carried out for different flow schemes
