massive quantities continuously through devices while they are subject
to chemistry, thermodynamics, and mass transport between phases.
The idea of absorption is simple: if we have a solvent with a different
solubility for CO 2 and N 2 , we can design a separation process such that
the exhaust and the fl ue gasses have the composition we desire.
However, depending on the type of solvent, the size of the separation
equipment can vary and energy requirements can differ. We will illustrate
