چکیده انگلیسی
The results of this evaluation indicate that the PEI-based sorbent process requires approximately 25% less regeneration steam than the conventional MEA process primarily due to avoiding the energy demand required for heat of vaporization of water in the MEA process. The PEI solid sorbent based process results in approximately 6.3 power plant efficiency point reduction as opposed to an 8 efficiency points for the MEA based process. The design of the fluidized-bed absorption and regeneration reactors in the novel solid sorbent process result in significant reductions in capital costs (21% reduction compared to MEA). The economic evaluation shows that the PEI-based solid sorbent process offers attractive reductions in the cost of electricity and the CO2 capture cost. The estimated cost of electricity, after adding the CO2 capture process, is found to be 85 and 81.7Â $/kWh for the MEA-based and PEI based process, respectively. Moreover, the cost of CO2 avoided for both process is estimated to be 69.8 and 62Â $/ton CO2 for the MEA and PEI process, respectively.
