METHOD OF SEPARATION OF GAS MIXTURE COMPONENTS Russian patent published in 1999 - IPC

FIELD: methods of separation of gas mixture components through liquefaction; various industries. SUBSTANCE: proposed method includes adiabatic cooling of gas mixture in supersonic nozzle and extraction of liquid phase. Prior to feeding the gas mixture to nozzle, it is twisted to centrifugal acceleration no less than 10000 g while passing through nozzle; extraction of liquid phase of each components is effected at point located at distance L from dew point of each component which is found from the following relationships L_i= v_i•τ_i, where L_i is distance between dew point of i-component and point of extraction of liquefied component, m; v_i is gas flow rate at dew point of i-component, m/s; τ_i is time of motion of drops of i-liquefied component from axis of flow to wall of nozzle, s; g is free fall acceleration, m/sq. s. EFFECT: enhanced efficiency of liquefaction of gas mixtures and separation of them into components. 1 dwg
