costs compared to the existing process. Hence, this metric is most com-
monly cited in research publications.
In the remainder of the carbon capture sections, we will discuss in
greater detail the three most commonly used gas separation processes:
Liquid absorption
: a liquid is used to selectively absorb CO

.
Solid adsorption:
a porous solid material is used to selectively
adsorb CO

.
Membranes:
a membrane is used to separate CO
