A process for ultrapurifying fumes or gases with total recovery of the resultant pollutants, characterised by: subjecting a stream of pollutant- containing fumes or gases to a sprinkle wash by unpolluted water within a snow producer (20) and subjecting the water, during its passage, to rapid cooling to a temperature sufficient to transform it into snow flakes, which along their path collect the pollutants present in the stream of fumes or gases, discharging from said snow producer (20) said snow flakes which have reached the base thereof, and feeding to a gasifier (56) the resultant polluted water deriving from said snow flakes.
La présente invention concerne un procédé d'ultrapurification de vapeurs ou de gaz avec récupération totale des polluants résultants. Ledit procédé consiste: à soumettre un flux de vapeurs ou de gaz contenant des polluants à un lavage par aspersion à l'aide d'eau non polluée dans un dispositif de production de neige (20) et à soumettre l'eau, lors de son passage, à un refroidissement rapide à une température suffisante pour la transformer en flocons de neige, qui sur leur chemin collectent les polluants présents dans le flux de vapeurs ou de gaz, à évacuer dudit dispositif de production de neige (20) lesdits flocons de neige qui ont atteint la base, et à alimenter vers un gazéifieur (56) l'eau polluée résultante dérivée desdits flocons de neige.
