A global perspective of co2 capture – an overview

There is growing concern that anthropogenic carbon dioxide (CO2) emissions are contributing to global climate change. Therefore, it is critical to develop technologies to mitigate this problem. The high capture cost and energy consumption would be a major barrier for implementing CO2 capture mitigation methods. Alternative technologies may offer improvement. This paper reviews several separation technologies applicable to CO2 capture from flue gas, and discusses improvement opportunities and research needs. The main object of the reviewers is to synthesize the novel chitosan based ionic liquid, as a potential solvent for post-combustion CO2 capture. To enhance the absorption performance of CO2 capture.
