    In downward delivery, CO2 drops to the bottom(underneath air).
    Does it stay there, because it is heavier, or does it diffuse into the air?
    If it diffuses into the air, doesn't that make Upward & Downward delivery unreliable?

    yes, there will be some diffusion, it's almost impossible to prevent. But if you have enough carbon dioxide formed then the overspill will diffuse rather than the vessel collected.
