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.
