A method of separating a liquid / liquid immiscible and system for its implementation Óoeuvre.

The present invention relates to a method and a system for separating a first liquid from a second liquid wherein the first liquid is partially or totally immiscible. The system includes a housing (12), an inlet (14) of fluid in said housing (12), a first output (24) of liquid in said housing (12), a second liquid outlet (34) in said housing (12) at least one coalescing assembly for coalescing said first liquid and at least one assembly for separating the droplets of said first liquid from said second liquid, said assemblies coalescence and separation being arranged in superposed relationship in said housing (12). This system and this separation method are particularly applicable in all purification systems of a liquid / liquid immiscible. In particular, they find application in the purification of an organic fuel containing water droplets.
