Definitions

  • the present invention relates to a method and apparatus for cryogenic separation of a methane-rich feed rate.
  • the product contains less than 2% carbon dioxide and less than 2% for the total oxygen and nitrogen content.
  • a flow rich in methane contains at least 30% methane.
  • Biogas for example from a non-hazardous waste storage facility (ISDND), is a mixture of methane, carbon dioxide, nitrogen, oxygen and traces of other impurities such as water and hydrogen sulphide or volatile organic compounds (VOCs).
  • ISDND non-hazardous waste storage facility
  • VOCs volatile organic compounds
  • the separation of CO2 and CH is preferably by permeation in a membrane system.
  • Membranes do not, however, make it possible to economically separate methane from gases in the air, but sharp purity requirements must be met for the injection of biogas into the natural gas network. It is then necessary to find a complementary means to separate the methane from the gases of the air.
  • adsorption system for this. This solution presents several disadvantages such as low efficiency, many wear parts or adsorbent bottles and very large buffer capacities.
  • a catalytic deoxygenator could solve this problem but gives rise to other problems such as the addition of an additional element in the process, the creation of water and C n H m or even coal or a potentially lower reliability of the assembly. biogas purification.
  • An object of the present invention is to find a solution in the form of a process which always ensures an operation of the distillation column out of the flammable zone.
  • feed rate denominates the flow entering the cold box, that is to say in the whole of the cryogenic distillation brick; this stream is already purified with CO2 and other impurities mentioned above.
  • a nitrogen enrichment is carried out by adding a nitrogen-rich flow rate to the distillation column. It is important to inject the nitrogen into the lower part of the column to avoid the flammability zone throughout the column.
  • the distillation column is withdrawn from a tank flow, the tank flow being enriched in methane with respect to the feed rate
  • the feed rate contains between 3 and 35% oxygen.
  • the feed rate contains between 65 and 97% methane
  • the feed rate contains between 3 and 35% in total of nitrogen and oxygen
  • the feed rate contains between 3 and 35% nitrogen; the nitrogen-rich flow contains at least 90% nitrogen, or even at least 95% nitrogen;
  • the feed rate is sent to a condenser-reboiler where it partially vaporizes the vessel liquid to form a vaporized gas, the feed flow totally or partially liquefied is sent from the re-reboiler condenser to the column and the vaporized gas is mixed with the nitrogen-rich flow; a nitrogen-rich liquid flow is vaporized by heat exchange with the feed rate to produce the nitrogen-rich gas flow;
  • an apparatus for cryogenic separation of a feed flow rich in methane containing oxygen and nitrogen comprising:
  • iv) means for withdrawing from the distillation column a liquid enriched in methane with respect to the feed rate and for sending it to the condenser-reboiler,
  • v) means for extracting from the condenser-reboiler a liquid rich in methane and for sending it to the exchanger
  • viii) means for sending a nitrogen-rich liquid to vaporize in the exchanger and means for sending the nitrogen-rich gas stream thus formed to a lower portion of the column mixed with the methane-rich gas to participate in the distillation.
  • the apparatus may comprise a storage of the nitrogen-rich liquid connected to the means for sending the liquid to vaporize in the exchanger.
  • FIG. 2 shows a simplified diagram of the method according to the invention.
  • a flow of feed gas 1 which may be a biogas comprises between 30 and 50% of methane, with a CH / CO2 ratio of between 1 and 2. It also contains air gases with a nitrogen / oxygen ratio greater than 3.7 and is saturated with water.
  • the gas 1 is purified by drying, by desulfurization and for removing the carbon dioxide it contains by permeation and / or adsorption in a treatment unit 2, so that it contains substantially only methane, nitrogen and oxygen.
  • a typical composition of the treated gas 4 could be 68% methane, 31% nitrogen and 3% oxygen.
  • This feed gas 4 produced by the processing unit 2 is cooled in a heat exchanger 3 of the plate and fin type at a pressure of between 6 and 15 bars.
  • the gas 4 is sent to a tank condenser-reboiler 5 of a simple distillation column 6.
  • the gas is cooled in the condenser-reboiler 5 and is at least partially condensed, while heating the vessel of the column 6
  • the fluid produced 7 by condensing the gas 4 is expanded in a valve 8 at a pressure between 1.1 and 5 bar abs. then sent to the top of column 6 as liquid 9.
  • the temperature of the liquid 9 must be greater than 90.7K to avoid the risk of solidifying the methane.
  • This liquid then separates in column 6 to form an overhead gas containing 84% nitrogen and 5% oxygen.
  • This gas 10 is heated in the exchanger 3 to form the waste gas 1 1.
  • the bottom liquid 12 of the column 6 is withdrawn with a composition of less than 100 ppm of oxygen, traces of nitrogen and the remainder being methane.
  • the tank liquid 12 is sent to the tank reboiler 5 where it partially vaporizes.
  • the formed gas is returned to the bottom of the column via line 21.
  • the remaining bottom liquid 13 vaporizes in exchanger 3 to form a pure methane gas product 14.
  • a liquid nitrogen storage 16 is connected to the exchanger 3 by a pipe 17 to vaporize the liquid nitrogen.
  • the vaporized nitrogen 18 is sent through an expansion valve 19 and the pipe 20 to the tank of the column 6, mixed with the vaporized methane 15 from the reboiler 5.
  • the vaporized nitrogen contains at least 90% nitrogen, or even at least 95% nitrogen. Mixing the nitrogen with the vaporized methane makes it possible to better disperse the nitrogen in the column and to avoid the formation of flammable "pockets".
  • the nitrogen may also come from an air separation apparatus producing nitrogen gas or a nitrogen gas network. If not nitrogen liquid from an air separation apparatus can vaporize in the exchanger 3 to supply the gas 20.
  • the feed gas can contain up to 10% oxygen or up to 5% oxygen.
