Membrane contactors for post-combustion carbon dioxide capture
Designing and studying gas/liquid contactors in order to capture carbon dioxide - A major step towards the intensification of post combustion capture

Almost unanimously, carbon dioxide is recognized as one of the main greenhouse gases (GHGs), contributing to global warming. To limit anthropogenic CO₂ emissions, one of the options advocated is the capture and storage of produced carbon dioxide (CCS) [11].

With this in mind, experts recommend amine capture as the mature technical solution for capturing 80-90% of CO₂ in post-combustion, with purity close to 90%. Under these conditions, the application of CCS comes up against two stumbling blocks: the economic cost of capture linked to the low CO₂ content (4 to 13% vol.) and the enormous volume of flue gas to be treated (over 1 million m³.h^–1 for a 700 MWe power plant), which presupposes a huge capture unit size, comparable to the size of the emitting thermal power plant. These two obstacles are due to the high nitrogen content introduced...
