Definitions

  • Air separation plant process for obtaining an argon-containing product and process for the construction of an air separation plant
  • the present invention relates to an air separation plant, a process for recovering an argon product by cryogenic separation of air, and a process for producing a corresponding air separation plant.
  • argon can be recovered in conventional air separation plants with known double column nitrogen-oxygen separation systems and an additional argon recovery unit.
  • argon accumulates in the region of the so-called argon transition in the low-pressure column (also referred to as the argon belly or argon bubble), where it reaches concentrations in the gas phase of up to 15%.
  • an argon-enriched stream is withdrawn slightly below this maximum argon from the low pressure column, so that it has a lower nitrogen content.
  • the argon-enriched stream is transferred to a so-called crude argon column.
  • the crude argon column is a separation column for argon-oxygen
  • the crude argon column can be formed by a one-part column, but there are also two- or multi-part columns, for example, in EP 0 628 777 B1, described.
  • Rohargon yarn an argon-enriched stream with a
  • Argon content of, for example, 10% fed In the crude argon column an argon-rich stream is obtained from this, which can be purified again in a downstream pure argon column. In the pure argon column can be an argon product with a content of up to 99.9999% argon or more can be obtained. This argon product is usually recovered in liquid form to facilitate storage and transportation. Processes for argon recovery of the type described are known, for example, from the following publications: DE 2 325 422 A, EP 0 171 711 A2,
  • EP 0 377 117 B2 (corresponding to US Pat. No. 5,019,145 A), DE 403 07 49 A1, EP 0 628 777 B1 (US Pat. No. 5,426,946 A), EP 0 669 508 A1 (US Pat. No. 5,592,833 A), EP 0 669 509 B1
  • Corresponding air separation plants are hardly any prefabricated, because the respective component groups usually can not be transported over longer distances. This means that they have to be created at the respective destination. This is disadvantageous for a variety of reasons, among others because appropriate personnel at the destination are either unavailable or expensive. The effort to create appropriate air separation plants thus increases significantly.
  • the invention is therefore based on the object to create an air separation plant of the type mentioned economically particularly favorable and operate.
  • the present invention proposes an air separation plant, a process for recovering an argon product by cryogenic separation of air and a method for producing a corresponding air separation plant with the features of the independent claims.
  • Preferred embodiments are the subject of the dependent claims and the following description.
  • an air separation plant which is set up for the production of an argon-containing product by low-temperature decomposition of compressed and cooled feed air.
  • the air separation plant has a high-pressure column, a multi-part low-pressure column and a multipart crude argon column.
  • the multi-part low-pressure column and the multi-part crude argon column each have at least one foot section and a head section arranged spatially separated therefrom.
  • the multi-part low-pressure column and the multi-part crude argon column are each formed in two parts.
  • the air separation plant operates on the basis of the principles explained above, wherein an argon-enriched stream of the low-pressure column of the air separation plant can be removed.
