A method and apparatus for implementing a method for separating fluids in emulsion and / or in solution, and / or low pressure distillation, in particular water and / or gaseous hydrocarbons dissolved in crude oil, and / or separating crude oil droplets emulsified in water, so as to obtain water with the necessary characteristics for its injection without contaminating underground aquifers, and / or, in the case of a predominance of the mixture in the crude oil, accelerating the settling of water in the lower part of the mixture, and / or low pressure distillation of the crude oil. The method creates a localized zone (5) of reduced pressure on a portion of the free surface of the treatment liquid (2) inside the closed treatment tank (1) without affecting the total pressure prevailing inside the closed treatment tank. |
