摘要： A centrifugal separator includes a rotor arrangement and a drive arrangement. A user of electric energy is arranged in the rotor arrangement. The centrifugal separator includes a rotary transformer, the rotary transformer including a transformer stator and a transformer rotor. The transformer stator and the transformer rotor are arranged adjacent to each other with an airgap therebetween. The transformer rotor includes a secondary coil and is rotatable together with the rotor arrangement. The secondary coil is electrically connected to the user of electric energy arranged in the rotor arrangement for providing the user of electric energy with an electric current. The user of electric energy may be an actuator, and/or a sensor, and/or a control unit.

摘要： The present invention provides method for separating contaminants from a liquid mixture comprising the steps of a) providing a feed of said liquid mixture to be purified, b) adding a separation aid to the liquid mixture to be purified, wherein said separation aid is capable of binding said contaminants and c) supplying a flow of compressed air into said feed after step b) has been performed to provide a feed comprising air. The method further comprises steps d) removing air from said feed comprising air to provide a deaerated feed; and e) supplying said deaerated feed to a separator, and f) separating a phase comprising contaminants and said separation aid from said liquid mixture in said separator, wherein the separation aid added in step b) is insoluble in said liquid mixture at the separation conditions in step f). The present invention further provides a system for separating contaminants from a liquid mixture.

摘要： A centrifugal separator includes a rotor arrangement and a drive arrangement. The centrifugal separator includes a generator for generating an electric current. The generator is configured for continuously generating a current during a full revolution of the rotor arrangement. The current is utilised for supplying electric current to a user of electric energy arranged in the rotor arrangement.
