Enhancing Efficiency of Corncob-Fired Power Generation with Carbon Capture and Storage

Bioenergy from biomass wastes with carbon capture and storage (CCS) is an important way to compensate for hard-to-abate emissions collaborate decarbonizing the energy industry. This work evaluates a corncob-fired power generation CCS regarding overall efficiency in two process alternatives: (a) post-combustion CO 2 by aqueous blend of methyl-diethanolamine piperazine; (b) oxy-combustion coupled state-of-art air separation unit. The alternatives are simulated Aspen HYSYS compared conventional plant evaluate penalty capturing . lean solvent composition optimized lowest regeneration heat demand (2.92 GJ/tCO ). Post-combustion designed 90% abatement presents 7.96%LHV. In contrast, Oxy-combustion has zero outperforms lower 6.77%LHV, given chance have oxygen supplied at cost 139 kWh/tO To render most efficient route, it would be necessary its reboiler ratio reduced 2.30
