GAS MIXTURE SEPARATION METHOD Russian patent published in 2012 - IPC F25J3/00 

FIELD: machine building.

SUBSTANCE: in separation method of gas mixtures containing solid phase, inlet gas is expanded in rotating flow in cyclone separator channel so that clean flow and flow enriched with specific fractions are obtained at the outlet of cyclone separator; at that, during expansion process 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 solid phase formation temperature. In addition, expansion degree of flow in cyclone separator is maintained so that P_inlet/P_clean>1.01 (whereP_inlet - full pressure of inlet gas, P_clean - full pressure of clean flow at the outlet of cyclone separator channel).

EFFECT: enlarging the operability range of gas mixture separation plants using gas expansion in cyclone separators, and providing their operability under conditions favourable for hardening of individual components included in composition of gas mixtures.
