Definitions
- Apparatus and method for cryogenic separation of a mixture of carbon monoxide and methane and hydrogen and / or nitrogen The present invention relates to an apparatus and method for cryogenically separating a mixture of carbon monoxide, methane and hydrogen and possibly nitrogen.
- the mixtures may consist of:
- Nitrogen with hydrogen impurities, carbon monoxide and methane (cold box nitrogen wash).
- An object of the invention is to make more compact a cryogenic separation apparatus of a mixture of carbon monoxide, hydrogen and methane when the methane must be produced under pressure.
- Another object of the invention is, in certain cases, to reduce the maximum height of a cryogenic separation apparatus of a mixture of carbon monoxide, hydrogen and methane. This reduces the cost of the device as well as the transportation costs.
- the liquid methane withdrawn from the tank of the CO / CH 4 column can be pressurized in a pump to be stored and / or sent to a customer or to be sent to the top of the methane wash column, if necessary.
- an apparatus for the cryogenic separation of a mixture of methane, carbon monoxide and hydrogen and optionally nitrogen comprising a first separation unit comprising at least a first column and or a phase separator, the first separation unit being supplied with the mixture, a first pipe for removing a gas enriched in hydrogen and possibly nitrogen from the first unit, a second pipe for discharging a liquid containing methane and monoxide of carbon of the first column or phase separator, a second column connected to the second pipe, a third pipe connected to the tank of the second column to withdraw a liquid enriched in methane and a fourth pipe connected to the head of the second.
- the second column for withdrawing a gas enriched in carbon monoxide or nitrogen, the first column and / or one or more separator (s) of being arranged below the second column, the two columns or the second column and the phase separator (s) having the same main axis, so that the methane-enriched liquid is produced at a higher pressure that the pressure of the tank of the second column, the second column comprising a tank reboiler characterized in that, where appropriate, when the apparatus comprises a first column, it does not include means for sending overhead gas from the first column to heat the bottom reboiler of the second column and in that the second conduit is a pipe connected to the tank of the first column.
- the apparatus comprises:
- a pump connected to the third pipe, disposed closer to the ground than the tank of the second column.

- the gas 21 withdrawn at the top of the column 19 is enriched in hydrogen and is heated in the exchanger 9 for recovery as a purge gas to a fuel system in general.
- the bottom liquid 23 of the column 19 contains mainly carbon monoxide (and nitrogen) and methane and is expanded in the valve 25 and then sent for separation in the column CO / CH 4 27.
- a gas 44 enriched in carbon monoxide is formed at the top of the column and a liquid enriched in methane 33 is formed in the bottom of the column.
- the liquid 33 is divided in two, a part 37 being reheated (or not) in the main cryogenic exchanger 9 for recovery as a purge gas (or in liquid form bypassing the exchanger 9) at the pressure of the column CO / CH 4 (a few bars) and the other part being pressurized by a pump 36 to feed the head of the methane washing column 17 and for possible upgrading under pressure (fluid 38) in gaseous form via the main cryogenic exchanger 9 (or directly in liquid form by short-circuiting the exchanger 9).
- a carbon monoxide cycle keeps the appliance cold. Carbon monoxide from the top of the column 27 is heated in the exchanger 9, sent as flow 45 to a compressor 51. Part of the Carbon monoxide is produced as pressurized gas 53 at the outlet of the compressor. Another part 57 cools in exchanger 9 and is divided in two. A portion 59 at an intermediate temperature of the exchanger 9 is expanded in a turbine 61 and sent via a valve 63 via line 65 to the compressor 51. Another part 67 continues to cool in the exchanger 9. A fraction 69 of the cooled carbon monoxide serves to heat the reboiler 22 of the depletion column 19 and is condensed.

- the methane enriched liquid 33 of the column vessel 27 passes through a height H to arrive at the pump 36 and is at a higher pressure due to the hydrostatic pressure.
