摘要： A method for removing at least part of carbon dioxide (CO 2 ) from a gas stream using a membrane that is permeable to CO 2 , having a first surface and a second opposing surface, said method comprising bringing the gas stream in contact with the first surface of the membrane, and bringing the second surface of the membrane with an aqueous solution comprising ammonia (NH 3 ) so that at least part of the CO 2 of the gas stream is removed from the gas stream and transferred through the membrane to the aqueous solution,
said method being characterized in that the gas stream has a steam (H 2 O) partial-pressure of at least 1200 Pa.-

摘要： 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.

摘要： Process wherein a low CO2 content process gas generated by an ammonia-soda process unit or a refined sodium bicarbonate unit is enriched by using a Temperature Swing Adsorption CO2 concentration module into a CO2 enriched gas whose CO2 content is increased by at least +10% by volume on dry gas basis relative to the process gas, and which is subsequently recycled to the ammonia-soda process unit or optionally to the refined sodium bicarbonate unit, in order: to produce sodium carbonate, or sodium bicarbonate, or to carbonate at least part of effluent from the unit for producing sodium carbonate or bicarbonate. The TSA CO2 concentration module comprises a stator and a rotor connected to the stator and rotatable relatively to the stator about a rotational axis, the rotor comprising a plurality of sectors, each sector containing a separation device to separate at least part of the CO2 from the process gas which is led into the separation device, and each sector being fluidically connected with at least one rotary active valve.
