Abstract (en)
[origin: WO2011113901A1] This filter comprises a plurality of reservoirs (1, 2 and 3) connected in series by connecting ducts (4, 5). The flow of gaseous streams therein is subject to multiple obstacles which have the effect of effectively trapping the constituents with the highest molecular weight without substantially impeding the diffusion of the light constituents. This can be achieved through the use of internal baffles (9) or an array (6) of thinner ducts (7), for example at the entry to the filter. Possible application to the separation of hydrogen and radon produced by nuclear waste.
