Two-phase separator device for removing condensate or particulate from a gas stream

A method of separating liquid or particulate from a gas stream, the method comprising:

• receiving a two-phase mixture of a gas stream and liquid or particulate through an inlet of a housing of a two-phase separator device;
• rotating a rotatable vane assembly of the two-phase separator device about an axis of rotation, wherein the rotatable vane assembly comprises a rotatable drum and a plurality of vanes connected to the rotatable drum at an inner wall of the rotatable drum, wherein the plurality of vanes are arranged about the axis of rotation and extend radially outwardly to the inner wall of the rotatable drum;
• flowing the gas stream through the rotatable vane assembly in an axial direction while the rotatable vane assembly is rotating, wherein the liquid or particulate of the gas stream is captured by the plurality of vanes without diverting the liquid or particulate while suspended in the gas stream and without diverting the gas stream radially outwards away from the axis of rotation, wherein the liquid or particulate is accelerated radially outwardly along one or more of the plurality of vanes after capture;
• and
• collecting the captured liquid or particulate by a pickup tube having an opening that is at least partially disposed within a channel that is formed along the inner wall of the rotatable drum.

• receiving a two-phase mixture of a gas stream and liquid or particulate through an inlet of a housing of a two-phase separator device;
• rotating a rotatable vane assembly of the two-phase separator device about an axis of rotation, wherein the rotatable vane assembly comprises a rotatable drum retained in the housing and a plurality of vanes connected to the rotatable drum at an inner wall of the rotatable drum, wherein the plurality of vanes are arranged about the axis of rotation and extend radially outwardly to the inner wall of the rotatable drum, wherein a plurality of grooves are formed in at least one major surface of each of the plurality of vanes, the plurality of grooves configured to capture liquid or particulate from the gas stream;
• and
• flowing the gas stream through the rotatable vane assembly in an axial direction while the rotatable vane assembly is rotating, wherein the liquid or particulate of the gas stream is captured by the plurality of grooves of the plurality of vanes without diverting the liquid or particulate while suspended in the gas stream, wherein the liquid or particulate is accelerated radially outwardly along one or more of the plurality of vanes towards the inner wall of the rotatable drum after capture, wherein the gas stream is flowed through the rotatable vane assembly in an axial direction parallel to the axis of rotation without diverting the gas stream radially outwards away from the axis of rotation, wherein the gas stream flows through the rotatable vane assembly to exit an outlet of the housing without axial or radial redirection.
