A gas separation centrifuge is provided with a housing having a top, a bottom and a plurality of joined side walls parallel to an axis and forming a predetermined regular polygon cross-sectional shape perpendicular to the axis. A rotor is mounted for coaxial rotation within the housing, including a plurality of inverted truncated pyramid plates forming the predetermined regular polygon shape at an outer periphery, and forming the predetermined regular polygon shape at an interior edge. The plurality of inverted truncated pyramid plates are stacked coaxially and are axially spaced apart to form planar channels therebetween and define an interior annular volume with openings therefrom into the planar channels. There are also openings through the outer periphery. A first plurality of stationary concentric input tubes extends into the interior annular volume. Each input tube is connectable to a source of inlet fluid and communicates with the interior annular volume at different distances along the axis terminating close to the bottom of the housing. A second plurality of stationary concentric output tubes also extends into the interior annular volume. Each output tube is connectable to a collection device and communicates with the interior annular volume at different distances along the axis close to the top of the housing. One of the plurality of input tubes is connected to a source of liquid solvent for injecting a quantity sufficient for coating the interior side walls to a thickness less than the minimum clearance distance between the exterior periphery of the rotor plates. A motor is connected for rotating the rotor at a speed sufficient to cause a maximum pressure above about 1,000 psi in the housing at the side walls. Another of the plurality of input tubes is connected to a source of a gaseous mixture. At least one of the outlet tubes has an opening at a position in the interior annular volume for withdrawing one gas of said mixture in a high state of purity.
