Definitions

  • This invention concerns processes and installations for providing gaseous carbon monoxide and/or a mixture containing at least 10% carbon monoxide.
  • it concerns the supply of carbon monoxide by vaporisation of liquid carbon monoxide when an industrial installation, such as a separation unit, cannot provide all or part of the gaseous carbon monoxide product.
  • the beds may contain adsorbents such as alumina or zeolites, such as molecular sieves.
  • the purification cycle can be adapted so that following the regeneration step, only a limited amount of feed gas is sent to the bed at the beginning of the adsorption step (around 5% of the normal feed flow).
  • EP-A-0837031 and EP-A-1245533 show a liquid carbon monoxide storage vessel incorporated at the top of a carbon monoxide-methane separation column, the liquid carbon monoxide being used to provide reflux for the column and to provide cooling for the methane wash column and, in the case of EP-A-0837031 for the main heat exchanger wherein the synthesis gas is used to its distillation temperature.
  • independent vessels collect liquid carbon monoxide used in the carbon monoxide cycle used in the methane wash process.
  • an installation for supplying gaseous carbon monoxide and/or a gaseous mixture containing at least 10% carbon monoxide by vaporisation of liquid carbon monoxide including
  • FIG. 1 shows an apparatus for separating a mixture containing principally methane, carbon monoxide and hydrogen.
  • the mixture may also contain small amounts of nitrogen, carbon dioxide, humidity, higher hydrocarbons etc.
  • This mixture is generally synthesis gas produced by a partial oxidation unit, a steam methane reformer or an autothermal reformer.
  • the mixture 1 is purified in a front end purification unit 3 at around ambient temperature to removed water and carbon dioxide. Then the mixture is cooled to a cryogenic temperature in a heat exchanger 5 and sent to the bottom of a methane wash column 7 operating at a pressure between 10 and 60 bars. A methane wash stream 9 is fed to the top of column 7 and a hydrogen enriched stream 11 is removed from the top of the column. From the bottom of the column is removed a liquid stream 13 enriched in carbon monoxide.
  • Stream 13 is further treated before being sent to the stripping column 19 which operates at between 4 and 17 bars, at least one feed stream formed from stream 13 being sent to the top of stripping column 19 .
  • the feed stream is feed thereto at a lower point.
  • the gas 21 from the top of the stripping column is warmed in the exchanger 5 and is used as fuel or burnt.
  • the liquid stream 23 from the bottom of the stripping column 19 is further treated before being sent to the column 27 .
  • several feeds (liquid, dual phase, gaseous) at different levels may be provided to the column 27 .
  • Column 27 operates at between 1 and 10 bars, often around 2.5 bars.
  • methane rich liquid 29 at the bottom of the column and a carbon monoxide rich gas 31 at the top of the column.
  • Part of the methane rich liquid is pumped and sent to the top of the methane washing column and the rest is removed as a purge stream.
  • the two portions of the methane rich liquid may be removed separately from the column.
  • the methane rich liquid is pumped by pump 33 and sent in part to the top of the methane washing column 7 and the remaining purge stream is mixed with stream 21 .
  • the part to be mixed with stream 21 need not be pumped.
  • the carbon monoxide rich product stream 31 is compressed in a compressor 35 and is removed as a compressed product gas 37 .
  • Refrigeration for the system is provided by a carbon monoxide cycle of which the compressor 35 forms part.
  • the carbon monoxide is compressed in compressor 35 to a pressure of between 10 and 60 bars.
  • Part of the compressed carbon monoxide 39 is cooled in exchanger 5 to an intermediate temperature of the exchanger and then expanded in turbine 41 .
  • the expanded carbon monoxide gas is warmed in the exchanger 5 and recycled to the compressor 35 at the entry thereof or an intermediate pressure thereof.
  • the unexpanded carbon monoxide 43 serves to reboil columns 19 and 27 and the thereby cooled carbon monoxide is expanded in valve 45 and sent to storage vessel 47 .
  • the storage vessel 47 forms an integral part of the column 27 and additionally serves to provide reflux to the top of column 27 , to supply liquid carbon monoxide to cool the methane wash column 7 and to supply liquid carbon monoxide directly to the main heat exchanger 5 where it is vaporised to balance the heat exchange diagram at the cold end of the heat exchanger 5 .
  • This independent storage vessel could be placed within or outside the cold box (not shown) which encloses the columns 7 , 19 , 27 , the exchanger 5 and the turbine 41 , optionally turbine 89 which expands part 87 of gas 71 .
  • the storage vessel may be pressurised so that the carbon monoxide is stored at between above 1 and below 60 bars. Ideally the storage vessel should be at a pressure which is substantially the product pressure of the carbon monoxide gas 37 or the carbon monoxide mixture 73 , allowing for pressure drop in the conduits and vaporiser 53 . Alternatively the carbon monoxide may be stored at atmospheric pressure and then, if required, pumped in liquid form and/or compressed in gaseous form to its final pressure.
  • Flash gas 49 produced by the expansion is mixed with the carbon monoxide rich gas 31 prior to compression.
  • a stream of liquid carbon monoxide 57 is vaporised in exchanger 59 against the gas streams within the methane wash column 7 and forms part of the gaseous carbon monoxide cycle.
  • a further stream of liquid carbon monoxide 61 withdrawn from the vessel 47 is vaporised in exchanger 5 .
  • liquid 51 from the storage vessel 47 is withdrawn when required and vaporised in the vaporiser 53 .
  • the vaporiser may either allow heat exchange with ambient air, water or steam if it is outside the cold box or may be within the cold box and may be constituted by the exchanger 5 or another heat exchanger.
  • the vaporised carbon monoxide produced 55 is sent to the compressor 35 to form all or part of the product gas.
  • the liquid to be vaporised 51 is available at high pressure, for example following a pumping process upstream of the vaporiser 53 or where the liquid is stored at high pressure, the gas produced can be directly mixed with the product gas 37 .
  • the withdrawal and vaporisation of the carbon monoxide may take place
  • the level in the storage vessel will remain constant or will rise. The level will fall whenever one of the conditions is fulfilled and the vessel will need to be replenished, for example when the amount of feed gas increases and/or when the adsorbers are saturated with carbon monoxide and/or when the product requirement is less than the maximum capacity of the separation unit.
  • the carbon monoxide turbine needs to be overdimensioned to replenish the vessel or else a cryogenic liquid from an outside source can be added.
  • This cryogenic liquid may be liquid carbon monoxide from an outside source or liquid nitrogen which is then used to liquefy gaseous carbon monoxide by heat exchange in a heat exchanger.
  • the adsorbers are operated as described in FR01/06041 (incorporated by reference) such that the amount of feed sent to the adsorbers does not reach its full amount until the adsorber bed to which it is sent is saturated with carbon monoxide.
  • the flow starts at 5% mol. of the normal flow, then is increased to 50% mol. and finally is increased to 100%.
  • the liquid carbon monoxide may begin to be sent to the vaporiser for example when the flow is at its smallest or alternatively may begin a few minutes before the flow is at its smallest.
  • the liquid carbon monoxide is no longer sent to the vaporiser once the flow has increased to 50%.
  • Gaseous and liquid carbon monoxide are defined to be respectively a gas and a liquid containing at least 85% carbon monoxide, preferably at least 95% carbon monoxide.
  • the process may also be used to produce a mixture containing at least 10% carbon monoxide 73 , for example an oxogas used in the production of oxoalcohols.
  • This mixture is produced by withdrawing a gaseous mixture 71 from one of the columns of the system, warming it in exchanger 5 and enriching it by adding gaseous carbon monoxide 72 to achieve a desired concentration of carbon monoxide. Where the gaseous carbon monoxide is insufficient, part of the requirement may be provided by vaporising part of the carbon monoxide liquid from storage 47 .
  • cryogenic separation processes for mixtures containing carbon monoxide and at least one of hydrogen, nitrogen and methane as principal components, for example processes to separate mixtures of hydrogen, carbon monoxide and methane such as the partial condensation process or processes for separating mixtures containing carbon monoxide and nitrogen only as principal components.
  • the separation unit shown here as a cryogenic distillation unit could of course operated by permeation in a membrane system or by adsorption.
  • the liquid carbon monoxide could be imported from an external source or could be produced by liquefying part of the gaseous carbon monoxide product at times of low demand.
