Abstract: A separator includes: a centrifugal drum; a drive spindle, where the drive spindle is rotatably mounted in a drive housing by a neck bearing and a foot bearing, and where the drive housing encloses a drive chamber; an electric motor which has a stator and a motor rotor, where the motor rotor is disposed on the drive spindle, where the stator is fixedly connected to the drive housing, where an air gap exists between the stator and the motor rotor, and where the stator and the motor rotor are arranged between the neck bearing and the foot bearing; a lubricating system for lubrication of the neck bearing and the foot bearing; and a coolant system; where the stator has a flange section which is disposed on a collar section of the drive housing.

Abstract: A method for on-ship processing of heavy oil which is to be utilized as fuel is disclosed. In an embodiment, the method includes providing the heavy oil for processing. The heavy oil is passed using a pump into a centrifuge with heating of the heavy oil, at least intermittently or permanently, to a separation temperature of more than 98° C. before the heavy oil reaches the centrifuge. An aqueous phase and a sludge phase are separated from a clean oil phase in the centrifuge.
