Process and apparatus for the separation of oil and water emulsions and / or degasification of oil mixtures on the basis of the Bernoulli laws

摘要

Disclosed is a process for dehydration and degasification of crude petroleum solutions or emulsions with water, contained into a closed processing tank (such as a hydrocyclone) so as to obtain water with the necessary characteristics for injection without pollution of underground aquifers, and acceleration of settling of the water in a lower part of emulsion or solution, the process comprising: a) compressing a processing gas; b) generating a current of said processing gas compressed; and c) projecting said current of the said processing gas tangentially over a localized zone within the said closed processing tank without the overall pressure inside the closed processing tank being affected, 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; the current of said processing gas making an angle, before coming into contact with the free surface of said emulsion or solution, which varies between zero and thirty degrees, the pressure reduction bringing about rapid separation of the fluids in the emulsion or solution; and wherein the creation of said localized zone of reduced pressure can be achieved by the use of a Venturi static machine.
