METHOD OF CLEANING FLUE GASES FROM GASEOUS CONTAMINATING COMPONENTS Russian patent published in 1999 - IPC

FIELD: cleaning of atmospheric air from harmful effluents in any industry. SUBSTANCE: method includes determination of quality composition of flue gases, changing of temperature to value at which contaminating gases turn into liquid state with withdrawal of them from flow; determination for each component of critical values of temperature and pressure; supply of flue gases to zone of high pressure with its further gradual increasing up to attaining of critical value for each component; change of temperature to its critical value for each component simultaneously with attaining of critical pressure value. EFFECT: higher efficiency of cleaning. 2 tbl
