METHOD OF RETRIEVING COMPONENTS FROM NATURAL AND PETRACTION OF TECHNOLOGICAL GAS MIXTURES ON NANOPOROUS MEMBRANES Russian patent published in 2017 - IPC B01D61/36 C10L3/10 B01D53/22 B01D53/52 

FIELD: oil and gas industry.

SUBSTANCE: method of removing a gas mixture components, based on the passage of the gas mixture components through the nanoporous membrane selective absorption of liquid absorbent in contact with nanoporous membrane in which to prevent gas in the liquid phase and liquid absorbent is vaporized using nanoporous membrane with uniform porosity (variance in size less than 50%) pore diameter in the range 5-500 nm, and the pressure difference between the gas phase and liquid absorbent support below the bubble point pressure membrane performance selection of acid gases (over 0.3 nm³/(m² h) on CO₂) when the packing density of the hollow fiber membrane to 3200 m²/m³, which corresponds to the specific volume capacity of removal of acid gases to 1000 nm³/(m³ h).

EFFECT: ensuring the effective extract of unwanted components of natural and technological gas mixtures.
