METHOD OF LIQUEFACTION OF GAS Russian patent published in 1999 - IPC

Abstract RU 2139479 C1

FIELD: liquefaction of gases; gas and oil producing industry, metallurgy, chemical industry and other industries. SUBSTANCE: method includes adiabatic cooling in supersonic nozzle and extraction of liquid phase; prior to feeding the gas flow, it is twisted to obtained centrifugal acceleration of 10000 g in flow of gas through nozzle; extraction of liquid phase in nozzle is effected at point located at distance from dew point determined form the following relationship: L = v•τ, where L is distance between dew point in nozzle and point of extraction of liquefied components, m; V is velocity of gas flow at nozzle inlet, m/s; τ is time of motion of drops of liquefied components from axis of flow to wall of nozzle, s; g is free fall acceleration, m/sq.s. EFFECT: enhanced efficiency of gas liquefaction. 1 dwg
