Abstract

The application of Electric swing adsorption (ESA) as a successful second generation technique to capture CO2 was evaluated. The objective of this work is to demonstrate that under certain conditions, ESA can be used in CO2 capture from flue gases of power plants. A process with seven steps was developed and tested for CO2 capture from a flue gas from a natural gas power station with emission levels of 1 Gton of CO2 per year with a content of 3.5%. The seven steps employed are: feed, rinse with hot gas, internal rinse, electrification, depressurization and two purge steps. Using this process we could obtain CO2-rich streams with purities of 89.7% keeping recovery around 70% and energy consumption of 1.9 GJ/ton of CO2 captured. © 2009 Elsevier Ltd. All rights reserved.
