[Digestion] water column CO2 scrubbing

[christian rodriguez]

Hello Alok:

What you're looking for, it's solubility of CO2 in
water...you may find it in Perry's Chemistry Manual.
Maybe in some other Chemistry Handbook under
solubility chapter.

By the way, CO2 dissolve better in low temperatures
and medium pressure (50 ~ 150 psi). Always consider
the energy demand of the project, so you can be an
"energy provider" instead of a "energy consumer"

Bye and good luck with your project.
