Abstract:
Method for continuously extracting impurities contained in a gas, said method comprising simultaneously a creation of a flow of gas between a suction opening and a gas outlet opening, a spraying phase of a liquid so as to generate a gas/mist mixture into an upstream portion of the gas flow, and an extraction phase of said mist in the downstream portion of said flow, wherein:said mist comprises liquid micro-droplets having a diameter of between 0.1 and 6 &mgr;m so as to obtain a first adsorption step of the impurities contained in said gas on said micro-droplets due to attracting forces exerted by said droplets on said impurities, said extraction phase comprising a second adsorption step of the mist by an adsorbent network provided with pores, meshes and passages having sizes higher than the size of said impurities so as to reduce load loss of the gas traversing it and avoid said network to be clogged and a density choosen so as to totally adsorb the mist passing there through and a desorption phase of the mist adsorbed by the adsorbent network.
