Solubility of co2 in ionic liquids,glycols,alkanolamins, esters and mixture of them

In the recent years, the issue of environment protection gradually attracts more and more attention, with sustainable development becomes the consensus of human beings. However, the serious emission of carbon dioxide is considered as a huge obstruction of this goal, thus various methods of carbon capture and storage turn into one of the research focus. Currently, only traditional absorbents are widely used in industrial applications, and their performance under actual conditions is not satisfied. Hence, in this review has studied solubility of co2 in ionic liquids ,glycols, alkanolamins , ,esters and mixture of them.also, this study mixture of ionic liquids(ILS)- glycols with ILS-alkanolamins are compared . glycol-alkanolamins and glycols are noticeable because they have low vapor pressure, high selectivity for co2 capture and they have suitable result when they use as cosolvent.There is some research about Esters and infer that DMC + diethyl carbonate is very strong solvent between famous esters and finally campered the suggested solvents in the latest researches and it recognaizable that the best solvent with suitable condition and more solubility for Co2 is mixture of alkanolanins and polyethylene glycols.
