Abstract:
1. A method for dehydration and degasification of crude petroleum solutions or emulsions with water, contained into a closed processing tank so as to obtain water with necessary characteristics for injection without pollution of underground aquifers, and acceleration of settling of the water in a lower part of an emulsion or solution, the method comprising: compressing a processing gas; generating a current of the compressed processing gas; and projecting the current of the processing gas tangentially along and onto a free surface of the emulsion or solution to be processed over a localized zone within the closed processing tank without affecting an overall pressure inside the closed processing tank, thus creating a localized zone of reduced pressure on a part of the free surface of the emulsion or solution to be processed within the closed processing tank, wherein the current of the processing gas makes an angle, before contacting the free surface of the emulsion or solution, which varies between zero and thirty degrees, the pressure reduction bringing about rapid separation of fluids in the emulsion or solution.
