Gas separation unit comprising a rotor with a plurality of sectors and a stator

A gas separation unit (1) for separation of a gas component (GC) from a process gas (PG) stream,

• wherein the separation unit (1) comprises a stator (20) and
• a rotor (10) which is connected to the stator (20) and is rotatable relatively to the stator (20) about a rotational axis (A),
• the rotor (10) comprising a plurality of sectors (16),
• each sector (16) containing a separation device (SD) arranged to separate the gas component (GC) from the process gas (PG) stream which is led into the separation device (SD),
• wherein each sector (16) is fluidically connected with at least one valve (40),
• wherein the valve (40) is a rotary active valve (40), the rotary active valve (40) comprising a stator open area (23) which is located in a stator valve region (28) of the stator (20),
• wherein the rotor (10) comprises a rotor valve region (18) having a
• rotor solid area (13) which is overlappable with the stator open area (23) in order to close the valve (40), and a rotor open area (14) which is overlappable with the stator open area (23) in order to open the valve (40),
• wherein an extent of overlapping of the stator open area (23), the rotor solid area (13) and the rotor open area (14) is changeable by a rotation (R) of the rotor (10) relative to the stator (20);
• wherein the stator (20) comprises two stator discs (24) which are arranged at each axial end of the rotor (10), and wherein diffusors (25) are arranged in radial direction and on the outside of the stator discs (24).
