  • Patent number: 10744448
    Abstract: Gas separation unit for separation of a gas component from a process gas stream, said separation unit comprising a stator and a rotor comprising a plurality of sectors, each sector containing a separation device arranged to separate the gas component from the process gas stream which is led into the separation device and each sector being fluidically connected with at least one valve. The valve is a rotary active valve which comprises a rotor open area which is located at the rotor and a stator open area which is located at the stator. The rotor open area and the stator open area can overlap and can be laterally separated from each other by rotation of the rotor relative to the stator. In this way, the valve can at least partially be opened and closed. The extent of overlap of the rotor open area and the stator open area defines the extent of opening and closing of the valve, respectively. The extent of overlap corresponds to the extent of partial opening of the valve.
