Abstract
Abstract A gas mixture containing a heavy component and a light component, e.g. for the enrichment of the gas mixture in uranium 235 in which the uranium isotopes are provided in the form of uranium hexafluoride, comprises accelerating the gaseous mixture through a centrifuge in a radial direction and inducing the formation of turbulence along the outer periphery of the centrifuge. Because of the turbulent flow in this region, a boundary layer is formed along the outer periphery of the centrifuge and the heavy component tends to diffuse out of this boundary layer. The light fraction is collected from the boundary layer and conducted away.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
143 words
A process for at least partial separation of a light component from a heavy component in a gas mixture, comprising the steps of: radially accelerating said gas mixture in a disk centrifuge having a periphery at which a radial passage in said disk opens and from which the gas mixture emerges and inducing turbulent flow along said periphery having a substantially uniform eddy-current formation with a substantially smaller degree of turbulence than the potential flow outwardly thereof in a manner such that a boundary layer enriched in said light component is formed along said periphery; and recovering gas enriched in said light component from said boundary layer by inserting into said boundary layer, proximal to said periphery but externally of said disk and opening toward said periphery, a plurality of conduits and withdrawing the gas enriched in the light component from said conduits.
Claim 2
Dependent Claim
143 words
A process for at least partial separation of a light component from a heavy component in a gas mixture, comprising the steps of: radially accelerating said gas mixture in a disk centrifuge having a periphery at which a radial passage in said disk opens and from which the gas mixture emerges and inducing turbulent flow along said periphery having a substantially uniform eddy-current formation with a substantially smaller degree of turbulence than the potential flow outwardly thereof in a manner such that a boundary layer enriched in said light component is formed along said periphery; and recovering gas enriched in said light component from said boundary layer by inserting into said boundary layer, proximal to said periphery but externally of said disk and opening toward said periphery, a plurality of conduits and withdrawing the gas enriched in the light component from said conduits.
Claim 3
Dependent Claim
26 words
The process defined in claim 1 wherein said gas mixture is a mixture of the hexafluorides of uranium isotopes, the light fraction being uranium 235 hexafluoride.
