Diffusion separation process

scroll

lsotope separation procedure using the different diffusion speeds of atoms or molecules of different weight through a porous wall for separation. The degree of enrichment of the lighter component after flowing through the separation wall is determined by the root of the mass ratio of the particles. The diffusion separation process is employed on an industrial scale for uranium isotope separation where UF6 is used as a process medium. The separation factor per stage amounts to about 1.002. Connection in series in cascade form multiplies the separation effect. A uranium isotope separation plant according to this procedure is operated in Pierrelatte, north of Avignon.
