XENON ISOTOPE SEPARATION CASCADE Russian patent published in 2006 - IPC B01D59/00 B01D59/20 

FIELD: physics of elementary particles, neutrino, for example.

SUBSTANCE: proposed cascade includes separating steps each of which is connected by inter-step pipe lines for transfer of xenon flow of light fraction of previous step to supply line of next step and for transfer of xenon flow from heavy fraction of subsequent step to supply line of previous step. Cascade is also provided with pipe lines for delivery of gas mixture to supply line of one of steps and discharge of separated flows of xenon light and heavy fractions from cascade. Inter-step pipe lines are provided with coolers over entire length of cascade, at least every 5 steps. Besides that, additional coolers are mounted on pipe lines at outlets of separated flows of xenon light and heavy fractions. Coolers are hollow and have U-shaped or loop-shaped profile at temperature of (-70)-(-78)°C.

EFFECT: increased productivity of each step and cascade as a whole; increased separating capacity; removal of admixtures and water vapor.
