Helikon Vortex Separation Process

Chapter 6 Useful Applications of the RHVT

Paul Dirac proposed the vortex tube for isotope separation. This proposal leads to the Helikon vortex separation process used by The Uranium Enrichment Corporation of South Africa to separate Uranium isotopes. However, the low level of efﬁciency led to the project being discontinued. Some authors report on the separation of gases using …

Helikon Vortex Separation Process

Helikon Vortex Separation Process - Process. Process. In the vortex separation process a mixture of uranium hexafluoride gas and hydrogen is injected tangentially into a tube at one end through nozzles or holes, at velocities close to the speed of sound. The tube tapers to a small exit aperture at one or both ends.

The Helikon vortex separation process is an aerodynamic uranium enrichment process designed around a device called a vortex tube. Paul Dirac thought of the idea for isotope separation and tried creating such a device in 1934 in the lab of Peter Kapitza at Cambridge. Other methods of separation were more practical at that time, but this …

The Origins of Vortex Separation | Treatment Plant Operator

Hydro's founding father, Bernard Smisson, designed the very first vortex overflow in England in the 1960s. Faced with space constraints while constructing a conventional side overflow, he developed a circular overflow configuration based on a vortex flow regime. As a result, hydrodynamic vortex separation technology was …
