Ionic Liquid Solvents as Advanced Treatment Method for CO2Control: A Review Research

Abstract

Climate change issues have risen in recent years due to human activities produce carbon dioxide (CO2) emissions. By 2021, the Intergovernmental Panel on Climate Change predicts a temperature increase of 1.9 C. CO2 reduction is crucial for humans and all other forms of life on Earth. To mitigate this potential issue, immediate improvements in CO2 separation processes are needed. One of the most efficient methods in separating it is to use water amine chemical absorption as an ionic liquid solvent. Therefore, this paper addresses common solvents used in this respect, such as alkanolamine, ionic liquid and their mixed aqueous solutions in the absorption process. The success factors in the mass are the transfer phenomenon between CO2 and solvent. The physical factors were examined, and the chemical properties of liquid ionic solvents were examined.
