I have to remove CO2 from bio gas. Let me know a viable process?

Co2 in biogas should be removed . The initial concentration is around 45% and finally it should be reduced to 3%. Is water absorption viable? what are the other possible CO2 removal methods?

    Growing plants take up CO2 in the sunlight almost instantly. You could put the biogas(?) in a bottle and cool it. CO2 is heavier than O2, N2, and methane. Freeze it, you get dry ice. Pass it thru barolyme and will be absorbed out.
