Apparatus and methods for dissolving carbon dioxide in water

A method for prevention of fouling of pipes, comprising:

• passing the water through a conical tubular apparatus, the conical tubular apparatus having a water inlet at a top end thereof and a water outlet at a bottom end thereof, the top end being the narrow most portion of the conical tubular apparatus, wherein a velocity of the water, as it passes through the conical tubular apparatus from the top end to the water outlet, slows, wherein a cross-sectional inside diameter of the conical tubular apparatus continually increases from the top end to the bottom end thereof;
• introducing carbon dioxide into the conical tubular apparatus adjacent the top end;
• flowing the water through the conical tubular member to dissolve the carbon dioxide into the water as a carbon dioxide enhanced outflow, wherein a buoyant rise velocity of bubbles of carbon dioxide is greater than the velocity of the water through the cone, suspending the bubbles inside the cone;
• and
• passing the carbon dioxide enhanced outflow through the pipes.

A method for reducing an amount of carbon dioxide in the atmosphere, comprising:

• scrubbing air to remove a carbon dioxide volume therefrom;
• passing the water through a conical tubular apparatus, the conical tubular apparatus having a water inlet at a top end thereof and a water outlet at a bottom end thereof, the top end being the narrow most portion of the conical tubular apparatus, wherein a velocity of the water, as it passes through the conical tubular apparatus from the top end to the water outlet, slows, wherein a cross-sectional inside diameter of the conical tubular apparatus continually increases from the top end to the bottom end thereof;
• introducing a carbon dioxide volume into the conical tubular apparatus adjacent the top end;
• flowing the water through the conical tubular member to dissolve the carbon dioxide into the water as a carbon dioxide enhanced outflow, wherein a buoyant rise velocity of bubbles of carbon dioxide is greater than the velocity of the water through the cone, suspending the bubbles inside the cone;
• and
• sequestering the carbon dioxide enhanced outflow into an injection well.
