Definitions
- the present invention relates to a method and apparatus for producing carbon monoxide by cryogenic distillation.
- known methods for producing hydrogen and / or carbon monoxide by cryogenic distillation it is common to use a denitrogenation column to obtain very low nitrogen products from a mixture to be separated contaminated with carbon dioxide. 'nitrogen.
- nitrogen is injected upstream of the denitrogenation column, preferably in the circuit followed by the CO (synthesis gas or cycle), preferably at low pressure, thus making it possible to operate the denitrogenation column.
- the nitrogen-rich fluid is injected into a flow supplying the denitrogenation column or the nitrogen-rich fluid is injected directly into the denitrogenation column;
- the nitrogen-rich fluid is injected at a temperature above -170 ° C., optionally above 0 ° C.
- the nitrogen-rich fluid is a liquid or a gas
- the nitrogen-rich fluid is sent from an external source other than the source from which the mixture originates upstream of the denitrogenation column;
- the column system makes it possible to carry out a partial condensation or a methane washing upstream of the denitrogenation column.
- a facility for producing carbon monoxide by cryogenic distillation comprising a system of distillation columns, means for supplying the column system with a mixture comprising at least hydrogen and carbon monoxide as main components and at least part of the nitrogen time, the column system comprising a denitrogenation column for producing a nitrogen-enriched flow rate and a nitrogen-free flow rate and means for withdrawing from the column system a carbon monoxide enriched stream for use as a product and means for delivering a nitrogen-rich fluid from an outside source, other than the source from which the mixture originates, upstream of the denitrogenation column or up to the denitrogenation column, characterized in that it comprises means for measuring
- the nitrogen content of the mixture a fluid whose mixture is derived or a fluid (9) supplying the denitrogenation column or ii) the purge flow of a condenser (23) of the denitrogenation column; or fluid supplying the denitrogenation column or iii) the opening of an expansion valve (31) of the purge of a condenser of the denitrogenation column and control means capable of delivering the nitrogen-rich fluid (17) from an external source, other than the source from which the mixture originates, upstream of the denitrogenation column and / or the denitrogenation column depending on the measured content or the measured flow rate or the measured opening.
- the means for bringing a nitrogen-rich fluid from an external source are connected to an inlet of the denitrogenation column;
- the plant comprises means for measuring the nitrogen-enriched flow rate and control means capable of sending the nitrogen-rich fluid from an external source other than the source from which the mixture comes from upstream of the column of nitrogen. deazotation if the measured flow is below a given threshold;
- the column system comprises means for carrying out a partial condensation or a methane washing upstream of the denitrogenation column.
- the apparatus comprises at least two distillation columns, one column CO / CH 4 5 and a denitrogenation column 11.
- the apparatus may be part of an installation with a methane wash step or a partial condensation step upstream of the CO / CH 4 column.
- the denitrogenation column may also be upstream of the CO / CH 4 column.
- the CO / CH4 column is fed with two flow rates 1, 3 at different levels and produces a liquid rich in methane 7 and a fluid 9 rich in carbon monoxide 9 but containing nitrogen at least from time to time.
- the fluid 9 is sent to the denitrogenation column 11 in the upper part of the column.
- the tank liquid 13 is sent to a top condenser 23 of the denitrogenation column 11 in order to condense the nitrogen 25.
- a purge flow 27 is withdrawn from the condenser 23, sent to a heat exchanger 29 where it vaporizes and The pressure of the denitrogenation column 11 is maintained by means of the purge flow 27. If the nitrogen content of the flow rate 9 and / or the flow rate 9 itself and / or the purge flow 27 drops below a given threshold, a liquid or gaseous nitrogen flow 17 is sent to the top of the column. denitrogenation, until the nitrogen content of the flow rate 9 becomes acceptable. Additionally or alternatively, it is possible to measure the nitrogen content of the mixture, of a fluid from which the mixture is derived (for example natural gas), and to trigger the sending of nitrogen if this content is below a given threshold. .
- Another alternative is to trigger the sending of nitrogen if the opening of the expansion valve 31 of the purge of a condenser of the denitrogenation column reduces below a given threshold.
