Which equation is used for the dissolution of CO and hydrogen in water?

CO and hydrogen are dissolved in water; hydrogen is suitable for the SRK equation but not for the NRTL equation. So, which equation is more appropriate for describing the absorption of CO and hydrogen by water?

Can water absorb these two things? That’s the question.

The equation of state is more appropriate; generally, for this system, there is a significant difference between the activity coefficient equation and the equation of state at high pressures, while at low pressures (1 KGF/cm2) the difference is not significant.

Use SRK; if the hydrogen and CO concentrations are not high, you can try the HENRY option
