Patent ID: 8425670

Claim:
A plant for separating oil in the form of particles and/or mist from a fossil gas mixture for obtaining a separated gas, wherein the plant comprises a gas conduit and a centrifugal separator provided on the gas conduit, wherein the centrifugal separator comprises a stationary casing, which defines a separation space permitting a gas flow therethrough, an inlet for the gas mixture through the casing into the separation space, a separating member for separating the gas mixture, which comprises a plurality of separating discs and a central outlet chamber provided inside the separating discs and which is provided in the separation space, a drive motor, which via a spindle is connected to the separating member and arranged, during the separation, to rotate the separating member via the spindle in a direction (r) of rotation about an axis (x) of rotation at a number of revolutions which lies within a range of revolutions, wherein the separating member is configured to separate oil from the gas mixture by means of centrifugal forces, a gas outlet which with respect to the gas flow is provided downstream the separating member and is directly connected to the central outlet chamber for discharge of the separated gas, an oil outlet for discharge of oil, wherein the oil outlet extends through the casing, the stationary casing is configured in such a way that it permits a pressure of at least 10 bars in the separation space during the separation, and wherein the plant is configured for counter flow separation in such a way that the gas mixture is caused to rotate and guided into the separating member radially from outside and in towards the central outlet chamber.
