Post-Combustion CO2 capture using supported amine sorbents: A process integration study

AbstractWe have evaluated the feasibility of supported amine sorbents (SAS) for their application in post- combustion CO2 capture. For this, the energy efficiency of a power plant equipped with a supported amine based capture facility is compared with the energy efficiency of a power plant equipped with a standard MEA-capture facility using the Spence®software tool developed by DNV-KEMA. Based on the simulations performed, application of a SAS-based capture facility at a natural gas combined-cycle (NGCC) plant is potentially 19% more energy efficient than a MEA-capture facility. For a pulverized- coal (PC) plant, the SAS-based plant could save up to 32% of the energy required in the MEA process
