Abstract

A method for extracting hydrocarbons from a vessel by displacement. The method including the displacement of a hydrocarbon source with a material of different density and recovery of the hydrocarbons from the vessel. Additionally, a method for extracting hydrocarbons from a vessel by gas displacement through chemical introduction. The method including introduction of hydrochloric acid and sodium bicarbonate into a vessel, production of carbon dioxide from the reaction of the hydrochloric acid and the sodium bicarbonate, displacement of a hydrocarbon source inside the vessel, and recovery of the hydrocarbon source from the vessel.

Claims (26)

1. A method for recovering hydrocarbons from a vessel comprising:

displacing a hydrocarbon source with a material, wherein the displacing comprises:

injecting at least one chemical that reacts to form a gas into the vessel, and

wherein the material has a density not equal to the hydrocarbon source; and

recovering the hydrocarbon source from the vessel.

2. The method of claim 1 further comprising injecting the material into the vessel.

3. The method of claim 1 wherein the at least one chemical that reacts to form a gas comprises sodium bicarbonate and hydrochloric acid.

4. The method of claim 1 wherein the at least one chemical that reacts to form the gas comprises salts and acids that react to generate gas.

5. The method of claim 1 wherein the material is a liquid.

6. The method of claim 1 wherein the material is a solid.

7. The method of claim 1 further comprising transferring the hydrocarbon source from the vessel to an oil platform.

8. The method of claim 1 wherein the hydrocarbon source is oil.

9. The method of claim 1 wherein the material is a gas.

10. The method of claim 1 further comprising:

injecting a material absorbing chemical into the vessel; and

removing the material with the material absorbing chemical.

11. The method of claim 10 wherein the material absorbing chemical comprises at least one of potassium hydroxide, ammonium chloride, ammonium hydroxide, methanol, and combinations thereof.

12. The method of claim 1 further comprising separating the hydrocarbons from water in a separator system.

13. A method of recovering hydrocarbons from a vessel comprising:

introducing hydrochloric acid and sodium bicarbonate into a vessel;

producing carbon dioxide from the reaction of the hydrochloric acid and the sodium bicarbonate;

displacing a hydrocarbon source inside the vessel; and

recovering the hydrocarbon source from the vessel.

14. The method of claims 13 further comprising injecting potassium hydroxide into the vessel.

15. The method of claim 13 further comprising injecting ammonium hydroxide into the vessel.

16. The method of claim 13 further comprising injecting methanol into the vessel.
