A device for phase separation of a multiphase mixture with at least one gas and at least two fluid phases may include a vessel including a tangential inlet via which the multiphase mixture is conveyed to the vessel, a tangential gas outlet above the inlet, via which a gas phase of the multiphase mixture separated from the multiphase mixture can be taken out of the vessel, and at least two outlets below the inlet at different vertical heights, via which one of the at least two fluid phases of the multiphase mixture respectively separated from the multiphase mixture can be taken out of the vessel. Further, a method for phase separation of a multiphase mixture using such device may include imparting an upwards-directed eddy flow to the multiphase mixture, during which fluid droplets are separated from the multiphase gas mixture, collecting the fluid droplets, and separately removing all phases formed.
