- the present invention proposes to solve these problems, while having other advantages.
- the condenser is bathed in cryogenic liquid, it overflows around the condenser over a hydraulic guard internal to the pot, the reserve of liquid is in the crown around this hydraulic guard. There is therefore only one equipment under pressure.
- a liquid storage capacity adapted to be incorporated in a cryogenic separation apparatus comprising an enclosure, a heat exchanger disposed inside the enclosure, a barrier dividing the two-part enclosure, the heat exchanger being located in the first portion and the second portion being disposed around the first portion, the barrier having a height less than the height of the enclosure, at least at certain points, so to allow the passage of liquid from the first part to the second part over the barrier, when the capacity is in use, and possibly being sealed in the bottom of the enclosure, means for sending liquid to the inside the first part enclosure and means for withdrawing liquid from the second part of the enclosure and means for sending a fluid to the exchanger and to take a fluid from the exchanger.
- the barrier has a substantially cylindrical shape
- the barrier is coaxial with the enclosure
- the first part of the enclosure, out of use, contains only the exchanger and the fluid transport means connected to this exchanger.
- the second part is supplied with liquid only by the overflow of liquid from the first part.
- a distillation column comprising a liquid storage capacity as described above in which the exchanger is a bottom reboiler or a top condenser.
- the distillation column is located outside the enclosure. According to another object of the invention, there is provided a process for producing carbon monoxide and / or hydrogen by cryogenic separation comprising a capacity as described above, said capacity being integrated with a separator pot.
- an apparatus for producing carbon monoxide and / or hydrogen by cryogenic separation comprising a column as described above in which the column is a separation column of carbon monoxide. carbon and methane or a carbon monoxide and nitrogen separation column.
- the apparatus comprises: - means for sending liquid inside the first part from at least two different sources and / or means for withdrawing liquid from the second part for then send them to two different destinations; a washing column and means for sending the sampled liquid at least to the cooler of the washing column, for example a methane or carbon monoxide washing column;
- a carbon monoxide and methane separation column or a carbon monoxide and nitrogen separation column and means for sending the sampled liquid to at least one head condenser of the carbon monoxide separation column and methane or the carbon monoxide and nitrogen separation column;
- a depletion column having a vessel reboiler and means for sending liquid from the reboiler vessel to the first part of the capacity;
- a carbon monoxide and nitrogen separation column having a bottom reboiler and means for sending liquid from the bottom reboiler to the first part of the capacity
- a carbon monoxide and methane separation column having a bottom reboiler and means for sending liquid from the bottom reboiler to the first part of the capacity; an exchange line and means for sending a liquid from the exchange line to the first part of the capacity.
- a process for producing carbon monoxide and / or hydrogen by cryogenic separation in an apparatus comprising a capacity as described above, said capacity being integrated with a separator pot .
- a process for producing carbon monoxide and / or hydrogen by cryogenic separation in an apparatus comprising a column as described above in which the column is a separation column. carbon monoxide and methane or a carbon monoxide and nitrogen separation column.
- the apparatus comprises a washing column and the liquid sampled is sent at least to the cooler of the washing column;
- the apparatus comprises an exchange line and the feed fluid is sent from the apparatus to the exchange line to cool thereon and the sampled liquid is sent at least to the exchange line;
- the apparatus comprises a carbon monoxide and methane separation column or a carbon monoxide and nitrogen separation column and the at least one withdrawn liquid is sent to a head condenser of the monoxide separation column; carbon and methane or the separation column of carbon monoxide and nitrogen;
- the apparatus comprises a depletion column having a bottom reboiler and liquid is sent from the bottom reboiler to the first part of the capacity;
- the apparatus comprises a carbon monoxide and nitrogen separation column having a bottom reboiler and liquid is sent from the bottom reboiler to the first part of the capacity;
- the apparatus comprises a carbon monoxide and methane separation column having a bottom reboiler and liquid is sent from the bottom reboiler to the first part of the capacity;
- the apparatus comprises an exchange line and a liquid is sent from the exchange line to the first part of the capacity;
- This device has several advantages.
- a single capacity serves at least two functions: on the one hand it stores an "independent" cooling reserve and on the other hand it is necessary for an element of the process (condenser, exchanger thermosiphon, etc.).
- This capacity can be fed by all the currents producing liquid in the cold box.
- the capacity is fed by at least two high-pressure flows through the reboilers, the high-pressure flow bypassing them. It can be powered by other flows, at different pressures.
- the fact of gathering all the currents in a single capacity brings a great flexibility if different cases of march are to be considered, rather than attributing to each high pressure fluid one or more uses low pressure (thermosiphon, condenser, etc.). In addition to flexibility, we also gain in standardization. If the pressure of the capacity allows it, all the liquid needs can thus pass through this capacity.
- the overflow makes it impossible to regulate the condensing power (in the example) by the liquid level, however, it is possible to regulate the energy exchanged in the condenser by adjusting the pressure of the capacity.
- the liquid reserve makes it possible to regulate the level by turbine or by flow rate. This also allows a reserve of liquid to operate the device when the turbine is down and before starting the vaporization of nitrogen feeding.
- FIG. 1 represents a capacitor and a column according to the invention
- FIGS. 2 to 4 diagrammatically show apparatus for producing carbon monoxide by cryogenic separation according to FIG. 'invention.
- a column 1 is surmounted by a top condenser 3 fed with a top gas from the column. This gas condenses at least partially in the condenser 3 and is returned to the top of the column.

- Part 7 is sent to the top condenser of the CO / nitrogen separation column K04.
- Part X evaporates in the cooling exchanger to form a flow 39. It is mixed with the vaporized flow rates 25, 37 from the condensers of column K03 and column K04 respectively.
- the mixed flow 43 joins the overhead gas of the separator pot 41 and cools in the exchanger 51.
- This flow 43 is compressed by a compressor C1.
- a compressed portion 45 is sent to the exchanger 49 and then is divided, the portion 31 feeding the column K04 and the remainder constituting the flow 19.
- the remainder of the flow 43 is compressed in the compressor C2 to form part of the flow 47 which, cooled in the exchanger 51, becomes the flow 15 for the capacity C.
- the compressor C3 compresses the rest of the flow to form the flow 49 which is divided in two. Part of the flow mixes with flow 49 and the remainder becomes flow 17.

- Part 11 is sent to the main exchange line where the mixture feeding the apparatus cools.
- Part 12 is sent to the head condenser of a column other than column 1, for example a carbon monoxide and nitrogen separation column, such as column K04 of FIG. 2.
- Each of these portions 9, 11, 12 vaporizes and is mixed with the vaporized liquid from the condenser 3.
- the mixed flow forms a cycle gas which is compressed in a multi-stage compressor, called compressors C1, CV and C2, connected in series.
- the compressor C1 compressed the gas to form a flow 45 which becomes the flow 19 downstream of the reboiler Q8.
- There may be a CV compressor which forms a flow 47 which is sent in part (147) to the reboiler Q6 and partly (149) to the reboiler Q8.
- the compressor C2 produces a flow 49 which feeds the reboilers Q6, Q7, the remainder forming the flow 20 also sent to the condenser 13.
- the process of Figure 4 represents a process for producing carbon monoxide and hydrogen by partial condensation.
- the apparatus comprises a separator pot 405, a depletion column 411 and a carbon monoxide and nitrogen separation column 1.
- Column 1 comprises a storage capacity according to the invention.
- Part of the synthesis gas is used to reboil the depletion column 411 by means of the reboiler 405.
- the gas of The partially condensed synthesis exits the exchange line 403 and is sent to the separator pot 405.
- the overhead gas 407 heats up in the exchange line and serves as a hydrogen-rich product.
- the liquid 409 is sent to the top of the depletion column 411.
- the overhead gas 410 of the depletion column 411 leaves the apparatus after heating in the exchange line 403.
- the tank liquid 415 of the column depletion 411 is sent to an intermediate point of the exchange line 403 where it cools and is divided into two.
- Part 419 is sent to separation column 1 after expansion.
- the remainder 417 heats up in the exchange line and is sent to the separation column 1 at a lower level.
- the tank liquid 449 of the separation column 1 is sent to the head condenser thereof where it partially vaporizes.
- the vaporized liquid rich in carbon monoxide 425 is sent to the exchange line 403 to heat up and then to the compressor C1.
- Carbon monoxide is cooled with water.
- a portion 453 serves as a product after a compression step in the compressor C2.
- the rest 451 cools in the exchange line.
- a portion 431 is expanded in a turbine T to provide frigories at separation and recycled to the compressor C1.
- the rest 433 is divided in two.
- Part 435 is sent to an intermediate temperature of the exchange line 403 at the bottom of the column 1 and at the top condenser (flow 437) after cooling in the exchanger 451 against a flow of liquid nitrogen 441.
- the remains 453 is sent to the condenser at the temperature of the cold end of the exchange line 403.
- the compressed cycle gas in the compressor C1 may be a gas rich in carbon monoxide, a gas rich in nitrogen or a gaseous mixture of hydrogen and carbon monoxide.
