Abstract

A system and method for reducing global warming. The system can include a container having a body portion for retaining a quantity of alkaline metal hydroxide and collecting a precipitate. At least one inlet on the container can be utilized for introducing a volume of air containing CO₂ into the alkaline metal hydroxide, so that the CO₂ in the volume of air can react with the alkaline metal hydroxide to reduce the amount of CO₂ in the volume of air and to form a precipitate in the body portion of the container. At least one outlet on the container can be included for releasing the volume of air having reduced CO₂ content into the atmosphere. A pump can be included for injecting the volume of air containing CO₂ into the alkaline metal hydroxide under pressure.

Claims

1. A system for reducing CO₂ in air comprising:

a reaction container configured for a gas-liquid reaction to occur therein;

a body of liquid solution comprising a quantity of calcium hydroxide in solution therein disposed in the reaction container, the reaction container being open to atmospheric pressure having a body portion for retaining the body of liquid solution comprising a quantity of calcium hydroxide in solution therein;

at least one inlet disposed in the reaction container for communication of gaseous air into and within the body of liquid solution within the reaction container;

the at least one inlet including a dispersal mechanism for introducing a finely dispersed volume of gaseous air containing CO₂ into and through the body of liquid solution comprising calcium hydroxide in solution therein to allow the CO₂ in the volume of air to react with the calcium hydroxide in solution in the body of liquid solution to produce a volume of gaseous air having a reduced CO₂ content therein and to form a precipitate of calcium carbonate in the body portion of the reaction container;

the dispersal mechanism configured to finely disperse the finely dispersed volume of gaseous air containing CO₂ throughout the body of liquid solution comprising calcium hydroxide in solution therein within the reaction container; and

at least one outlet from the reaction container for releasing the volume of gaseous air having reduced CO₂ content into the atmosphere,

wherein the body portion of the reaction container comprises a precipitate collection region adapted to collect the precipitate of calcium carbonate for removal from the container;

wherein the reaction container includes a valve or hatch or submersible vacuum for removing the precipitate of calcium carbonate from the container.

2. The system of claim 1, further comprising a filter having one or more of adsorbing material and a matrix of tortuous pathways for filtering the volume of air containing CO₂ prior to introducing the volume of air containing CO₂ into the calcium hydroxide to remove contaminant particles.

3. The system of claim 1, further comprising a pump for injecting the volume of air containing CO₂ into the calcium hydroxide under pressure.

4. The system of claim 1, further comprising a dispersal mechanism including one or more tubes disposed in the liquid solution, the one or more tubes having one end in communication with a source of air, and the other end plugged and therebetween multiple perforations within the body of liquid solution for introduction of the air from the one or more tubes into the body of liquid solution for efficiently dispersing the volume of air containing CO₂ throughout the calcium hydroxide.

5. The system of claim 1, further comprising at least one circulator or stirrer for maintaining the circulation and mixture uniformity of the calcium hydroxide.

6. The system of claim 1, further comprising a monitor for monitoring pH levels of the calcium hydroxide and providing notifications and alerts when the pH levels are not within predetermined threshold levels.

7. The system of claim 1, further comprising a vacuum for extracting the precipitate of calcium carbonate from the container.

8. The system of claim 1, wherein the body portion of the container collects a precipitate of calcium carbonate.

9. The system of claim 1, wherein the volume of air containing CO₂ is obtained from the atmosphere.

10. The system of claim 1, wherein the volume of air containing CO₂ is obtained from an industrial process that produces CO₂.

11. The system of claim 1, wherein the precipitate is sodium carbonate.

12. The system of claim 1, wherein the precipitate is magnesium carbonate.

13. The system of claim 1, wherein the precipitate collection region comprises a bottom of the container.

14. The system of claim 1, further comprising a precipitate collection system for collecting the precipitate of calcium carbonate from the precipitate collection region of the container.

15. The system of claim 14, wherein the precipitate collection system comprises a valve coupled to the container adapted to allow removal the precipitate from the container.

16. The system of claim 14, wherein the precipitate collection system comprises a hatch of the container adapted to remove the precipitate from the collector.

17. The system of claim 14, wherein the precipitate collection system comprises a submersible vacuum adapted to remove the precipitate from the precipitate collection region.

18. The system of claim 1, further comprising a cooling system configured to lower a temperature of the liquid solution.

19. The system of claim 1, further comprising a dispersal apparatus having perforations configured to be electronically, or mechanically actuated to open and closed positions to control dispersal of the volume of air into and through the body of liquid solution.

20. The system of claim 1, wherein the dispersal mechanism includes one or more perforations for finely dispersing the volume of air containing CO₂ throughout the calcium hydroxide in the container.
