FIELD: machine building. ^ SUBSTANCE: in separation method of gas mixtures containing water vapours, inlet gas is expanded in rotating flow in cyclone separator channel so that the flow containing no hydrates and flow enriched with water are obtained; at expansion stage some portion of gas, which flows near walls, is heated; heating is performed so that temperature of internal surfaces of cyclone separator channel is higher than hydrating temperature. In addition, expansion degree of flow in cyclone separator is maintained so that Pinlet/Pclean>1.1 (where Pinlet - full pressure of inlet gas, Pclean - full pressure of flow at the outlet of cyclone separator channel). ^ EFFECT: enlarging operability range of gas mixture separation plants containing water vapours and using gas expansion in cyclone separators, and providing their operability under conditions favourable for formation of hydrates in separator channel. ^ 4 cl, 3 dwg |
