Abstract: A method and a device for separation of a fluid in the liquid state comprising two liquids that are not mutually miscible, with different densities, wherein a first liquid is to be cleansed from a second liquid, whereby the fluid in the liquid state is conducted through a rotor where centrifugal separation of the second liquid from the first liquid takes place, and is then conducted into a tank (8), with the proportion of the second liquid being reduced to less than 5%, and by conducting the fluid, after centrifugal separation, through a restriction (9), whereby the pressure of the fluid in the liquid state is reduced, which causes portions of the fluid in the liquid state to evaporate so that further portions of the second liquid escape in the form of a gas which is conducted away, thereby further reducing the proportion of the second liquid in the outgoing fluid in the liquid state.
