Beschreibung
Zusammenfassung:	The invention relates to a method of phase separation of a mixture of at least two phases comprising the steps of introducing the mixture to a tank through an inlet and guiding the incoming mixture into a substantially upwards spiraling movement between the tank wall and an inner concentric cylindrical wall and separating the phases in a flotation and degassing zone wherein the tank is operated at a low pressure and the phases are selected from a group comprising: water, oil, gas and solid materials, where at least one of the phases is liquid under condition of operation.
