Problems solved by technology

Also according to the prior art, for large process tanks, in order to withstand negative pressure, their construction and installation costs will increase, and the risk of collapse caused by vacuum and explosion caused by filling fuel will also be more
[0003] Furthermore, according to the prior art, two or three phase separators are common in the hydrocarbon processing industry, these phase separators work on the basis of Stokes law to separate the liquid in the emulsion and the gas in the solution , this separation is very slow

Embodiment Construction

[0026] Fig. 1 has shown a kind of theoretical approach of implementing the method of the present invention, wherein, have the crude oil of emulsified water and dissolved gas, i.e. crude oil 2 to be treated, be imported in the closed treatment tank 1 through input pipe 2a, described crude oil 2 It will be stored in said treatment tank 1 until after treatment, leaving statically or dynamically through the outlet pipe 8 (ie the treated crude oil leaves the tank at the same time as the crude oil 2 enters the tank). The process gas 3 is compressed by a compressor 4, and the process gas stream 3 is injected tangentially onto the free surface of the crude oil by means of an injector 4a, before reaching said surface, said process gas stream 3 forms a specific angle with the free surface of said crude oil , the angle can vary from 0° to 30°, preferably 0-8°, more preferably 5°. In the area of ​​influence of the process gas stream 3 localized areas 5 of pressure reduction are formed on ...

Abstract

A process, and a device for implementing the process, for separation of fluids in emulsion and / or in solution, and / or for low pressure distillation, in particular of water and / or gaseous hydrocarbons dissolved in crude petroleum, and / or for separation of crude petroleum droplets emulsified in water, so as to obtain water with the necessary characteristics for its injection without pollution of underground aquifers, and / or when the mixture is dominant in crude petroleum, acceleration of the settling of the water in the lower part of the mixture, and / or for low pressure distillation of crude petroleum. The method creates a localized zone (5) of reduced pressure on part of the free surface of a liquid (2) to be processed, within a closed processing tank (1), without the overall pressure inside the closed processing tank being affected.

Description

technical field [0001] The present invention relates to a method for the separation of fluids in emulsions and / or solutions, and / or a method for low-pressure distillation of the components of said fluids, and to devices for carrying out said methods. The separation of said fluids is effected by locally lowering the relative pressure of a specific portion on the free surface of said fluids, a method which makes it possible to degas and separate liquids contained in closed process tanks without affecting the prevailing work pressure. Background technique [0002] According to the prior art, the above-mentioned separation is achieved by applying a partial vacuum to the whole of the processing equipment, and not only to a part of its interior. Also according to the prior art, for large process tanks, in order to withstand negative pressure, the construction and installation costs increase, and the risk of collapse due to vacuum and explosion due to fuel filling increases.
