Abstract
Abstract The application of Electric swing adsorption (ESA) as a successful second generation technique to capture CO 2 was evaluated. The objective of this work is to demonstrate that under certain conditions, ESA can be used in CO 2 capture from flue gases of power plants. A process with seven steps was developed and tested for CO 2 capture from a flue gas from a natural gas power station with emission levels of 1 Gton of CO 2 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 CO 2 -rich streams with purities of 89.7% keeping recovery around 70% and energy consumption of 1.9 GJ/ton of CO 2 captured.
