and CO 2 through carbamate formation (Ali et al. 2014; Adeyemi et al. 2017a, b) or
calcium carbonate production (Karimi et al. 2018)). Some of the studies concerning
SO 2 were carried out in simulated flue gas mixtures where the presence of N 2 is not
explicitly taken into account as it is just considered as a filler gas (Deng et al. 2019a).
Although in the cases where the gas reacts with the liquid absorber a value for
Henry’s law constant cannot be calculated, we have included in this report the values of K H even for reactive gases when published as such by the different authors.
In Fig. 4.1, Henry’s law constants, K H , of different gases in [Ch]Cl:U (1:2) are
presented. Hydrogen exhibits the lowest solubility (represented by the largest
Henry’s law constant) followed by carbon monoxide, nitrogen, and methane.
