Abstract

CO2 is extracted from the atmosphere by concentrating atmospheric air to form a first volume of the atmospheric air of increased level of CO2 and a second volume of reduced level of CO2, discharging the second volume back into the atmosphere and injecting the first volume into underground formations. The CO2 is concentrated by ionization and electrostatic separation of the charged particles from a stream and further concentration is carried out by molecular sieves. The first volume can be made miscible with oil and used to extract oil from oil-bearing formations or permanently stored in underground formations.

Claims

1. A method for extracting CO2 from the atmosphere comprising:

concentrating atmospheric air to form a first volume of the atmospheric air of increased level of CO2 and a second volume of reduced level of CO2;

discharging the second volume back into the atmosphere;

and injecting the first volume into underground formations.

2. The method according to claim 1. wherein the CO2 is concentrated by ionization of the CO2 and by electrostatic separation of the charged particles from a stream of the atmospheric air;

3. The method according to claim 2. wherein further concentration is carried out by molecular sieves.

4. The method according to claim 1. wherein the first volume is made miscible with oil and used to extract oil from oil-bearing formations.

5. The method according to claim 1. wherein the first volume is permanently stored in underground formations.

6. A method for extracting CO2 from the atmosphere comprising:

concentrating atmospheric air to form a first volume of the atmospheric air of increased level of CO2 and a second volume of reduced level of CO2;

discharging the second volume back into the atmosphere;

and applying the first volume to a quantity of water of pH sufficiently high so as to form carbonates in the water;

wherein the formation of the carbonates from the first volume acts to reduce the quantity of CO2 in the atmosphere.

7. The method according to claim 6 wherein the carbonates are extracted for commercial use.

8. The method according to claim 6. wherein the carbonates are stored at the sea bed or on land.

9. The method according to claim 6. wherein the pH of the seawater or other water is increased prior to mixing with the CO2 of the first volume.

10. The method according to claim 9. wherein the pH is increased by electrolysis.

11. The method according to claim 6. wherein the CO2 is concentrated by ionization of the CO2 and by electrostatic separation of the charged particles from a stream of the atmospheric air.

12. The method according to claim 11. wherein further concentration is carried out by molecular sieves.
