a) a chamber; b) a heat exchanger disposed inside the chamber; c) a barrier dividing the chamber into a first part and a second part; i) the heat exchanger disposed in the first part and the second part being arranged around the first part; ii) the barrier having a lower height than the height of the chamber, at least at certain points, for allowing liquid to pass from the first part to the second part over the barrier, when the enclosure is in service; d) means for sending liquid into the first part of the chamber; e) means for withdrawing liquid from the second part of the chamber; f) means for sending a fluid to the heat exchanger; and g) means for withdrawing a fluid from the heat exchanger. ### Claim 2 (depends on 1) The liquid storage enclosure of claim 1, wherein the barrier is sealingly attached to the base of the chamber. ### Claim 3 (depends on 1) A distillation column comprising a liquid storage enclosure as claimed in claim 1, in which the heat exchanger is a bottom reboiler or a top condenser. ### Claim 4 (depends on 1) An apparatus for producing carbon monoxide and/or hydrogen by cryogenic separation, comprising an enclosure as claimed in claim 1, said enclosure being included in a separator pot. ### Claim 5 (depends on 3) An apparatus for producing carbon monoxide and/or hydrogen by cryogenic separation, comprising a column as claimed in claim 3, in which the column is a column for separating carbon monoxide and methane or a column for separating carbon monoxide and nitrogen. ### Claim 6 (depends on 5) The apparatus of claim 5, further comprising means for sending liquid into the first part issuing from at least two different sources and/or means for withdrawing liquid from the second part to send it subsequently to two different destinations. ### Claim 7 (depends on 6) The apparatus of claim 6, further comprising a scrub column and means for sending the withdrawn liquid at least to the cooler of the scrub column. ### Claim 8 (depends on 6) The apparatus of claim 6, further comprising a heat exchange line; means for sending fluid from the apparatus to the heat exchange line to be cooled therein; and means for sending the withdrawn liquid at least to the heat exchange line. ### Claim 9 (depends on 6) The apparatus of claim 6, further comprising: a column configured to separate: i) carbon monoxide and methane, or ii) carbon monoxide and nitrogen; and means for sending the withdrawn liquid at least to a top condenser of the column. ### Claim 10 (depends on 6) The apparatus of claim 6, further comprising a stripping column having a bottom reboiler and means for sending liquid condensed in the bottom reboiler to the first part of the enclosure. ### Claim 11 (depends on 6) The apparatus of claim 6, further comprising a column for separating carbon monoxide and nitrogen having a bottom reboiler and means for sending liquid condensed in the bottom reboiler to the first part of the enclosure. ### Claim 12 (depends on 6) The apparatus of claim 6, further comprising a column for separating carbon monoxide and methane having a bottom reboiler and means for sending liquid condensed in the bottom reboiler to the first part of the enclosure. ### Claim 13 (depends on 6) The apparatus of claim 6, further comprising a heat exchange line and means for sending a liquid from the heat exchange line to the first part of the enclosure. ### Claim 14 (depends on 1) A method for producing carbon monoxide and/or hydrogen by cryogenic separation in an apparatus comprising an enclosure as claimed in claim 1, said enclosure being included in a separator pot. ### Claim 15 (depends on 3) A method for producing carbon monoxide and/or hydrogen by cryogenic separation in an apparatus comprising a column as claimed in claim 3, in which the column is a column for separating carbon monoxide and methane or a column for separating carbon monoxide and nitrogen. ### Claim 16 (depends on 14) The method of claim 14, in which liquid is sent into the first part issuing from at least two different sources and/or liquid is withdrawn from the second part to send it subsequently to two different destinations.
