Regeneration of solvent for CO2 capture: A review

Carbon dioxide (CO₂) is perhaps the most important greenhouse gas and it has been directly implicated in global warming. Fossil fuel-based power plants are one of the most important sources of CO₂ and their sustainable operation requires mitigation plans for the CO₂ emissions. Carbon capture is seen as the most viable way of mitigating the impacts of CO₂ emissions from power plants and other sources. The most commonly deployed strategy is post-combustion carbon capture utilising physical or chemical solvents for the absorption of CO₂. This paper gives an overview of the physical and chemical solvents used for post-combustion carbon capture as well as strategies available for regenerating these solvents.
