Abstract
An apparatus comprising first to third columns, wherein the outlet of a first column reboiler and the inlet of a second column condenser are connected by a first introduction conduit, and the outlet of a second distillation column reboiler and the inlet of a third column condenser are connected by a second introduction conduit, and additionally the outlet of the second column condenser and the inlet of the first column reboiler are connected by a first return conduit, and the outlet of the third column condenser and the inlet of the second column reboiler are connected by a second return conduit.
Claims4
An apparatus for distilling heavy isotopes from a vapor or a liquid constituted by a plurality of isotopes, comprising:
- a plurality of distillation columns constructed in a cascade,
- wherein each of the columns comprises a reboiler and a condenser;
- a liquid drawn from each of the columns being introduced into the reboiler;
- a vapor drawn from each of the columns being introduced into the condenser;
- an outlet of the reboiler of the first column is directly connected to an inlet of the condenser of the second column via introduction conduits, which introduce a portion of a vapor drawn from the reboiler of the first column into the condenser of the second column;
- the outlet of the reboiler of the first column is connected to the first column by means of a conduit which returns another portion of the vapor drawn from the reboiler to the first column;
- an outlet of the condenser of the second column is directly connected to an inlet of the reboiler of the first column via return conduits, which return a portion of a liquid drawn from the condenser of the second column into the reboiler of the first column;
- and
- the outlet of the condenser of the second column is connected to the second column by means of a conduit which returns another portion of the liquid drawn from the condenser to the second column.
