摘要：
The invention concerns a method for capturing very fine particles present in a fluid flux in liquid, gaseous or supercritical state and a device therefor. The method is characterised in that it comprises steps which consist in: causing said flux to pass through a filtering element (13); stopping the emission of said flux; countercurrent clearing of the filtering material (31) with a carbon dioxide flow under pressure, so as to drive the particles deposited on the filtering material (31); countercurrent expanding of the flux, so as to trap the particles within a solid carbon dioxide snow-type mixture formed during its expansion.
