EJECTOR MEMBRANE-SORPTION DEVICE FOR SEPARATION OF GAS MIXTURES Russian patent published in 2017 - IPC B01D53/47 

FIELD: oil and gas industry.

SUBSTANCE: ejector membrane-sorption device for separating gas mixtures contains a compressor to which an ejection mixer outlet is connected, at least two adsorbers filled with solid adsorbent through a gas pressure regulator and a desorption ejector inlet through a gas pressure regulator. The oulet of the ejection mixer through the gas flow regulator is connected to the first distribution valve. The adsorber inlets are connected to the first distribution valve to switch the flow of compressed gas from the compressor between the adsorbers. The outlets of the adsorbers are provided with control valves for withdrawing the gas from the adsorbers to the discharge pipeline and connected through a second distribution valve to the membrane filter, one of the withdrawal tubes is connected to the consumer and the second to the ejection mixer.

EFFECT: provide stationary operation mode for the membrane filter with continious feed and product flows and continious flow of displacement from the adsorbers to ensure the maximum separation characteristics of the device as a whole.
