Regeneration of solvent for CO₂capture: 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.
