Definitions

  • the invention relates to a product for producing a product by cryogenic separation of a gas mixture, in particular air, with a feed gas compressor for compressing the feed mixture, with a direct contact cooler for precooling the feed mixture, with a cleaning device for cleaning the pre-cooled feed mixture, with a low temperature part, the main heat exchanger for Cooling of the purified feed mixture to about dew point and a distillation column for cryogenic separation of the cooled feed mixture, and having a coolant circuit for supplying coolant for the direct contact cooler, wherein the coolant circuit has an evaporative cooler for cooling coolant in direct heat exchange with a gas stream from the low temperature part.
  • cryogenic temperature is meant here basically any temperature which is below the ambient temperature, but preferably a temperature of 200 K or less, most preferably 150 K or less, for example 100 K or less.
  • a direct contact cooler In a "direct contact cooler” the feed mixture is brought into direct heat exchange with a coolant, for example water, and thereby cooled. It is used in particular for removing heat of compression, which has arisen in a feed gas compressor, which is usually connected upstream.
  • a coolant for example water
  • a subsequent "cleaning device” is usually designed as an adsorption device and in particular has at least two switchable container, which are operated cyclically. It serves to separate unwanted components, for example those which can freeze out in the low-temperature part.
  • the feed mixture is first cooled to about dew point temperature and then decomposed in a distillation column system.
  • the low-temperature part thus contains one or more heat exchangers and one or more distillation columns.
  • the product is withdrawn in gas or liquid form.
  • the cryogenic part is usually thermally insulated by being enclosed by one or more cold boxes.
  • the “main heat exchanger” serves to heat the gaseous product (s) in indirect heat exchange with at least one feed mixture stream.
  • Direct contact coolers are often operated with coolant circuits in which at least a portion of the withdrawn from the direct contact cooler, heated coolant is cooled and returned to the direct contact cooler.
  • evaporative cooler dry gas is brought into direct countercurrent with coolant.
  • the coolant evaporates partially and is thereby cooled.
  • the dry gas is often available as a residual product in cryogenic plants, for example as impure residual nitrogen in an air separation plant.
  • direct contact coolers and evaporative coolers are arranged as a unit or at least as immediately adjacent units because of their functional relationship.
  • the invention has for its object to further optimize the arrangement of the components of a cryogenic separation plant to achieve a particularly high efficiency of the system.
  • the ratio of the distance between evaporative cooler and direct contact cooler to the distance between the evaporative cooler and the main heat exchanger is at least 0.5, in particular at least 1.0.
  • the evaporative cooler 15 is arranged comparatively close to the main heat exchanger. Although this means higher costs for the coolant piping; However, the line for the gas flow from the low-temperature part can be made very short. In the context of the invention has been found that this arrangement leads to a total of comparatively low investment costs costs. In particular, the effort for the pipelines and the associated steel construction costs is reduced. This is partly due to the very high cross section (for example 1 to 2 m) of the gas line to the evaporative cooler.
  • Atmospheric air is sucked in as "feed mixture” via an inlet filter 1 and fed via feed pipes 51, 52, 53, 54 to other plant components.
  • the filtered air 51 is compressed in a main air compressor, which in the example is the "feed gas compressor.”
  • the compressed air 52 flows into a direct contact cooler 3 where it is cooled in direct heat exchange with cooling water flowing over a cooling water piping 61.
  • the cooled air 53 is further passed into a purifier 4 having a pair of molecular sieve adsorbers 5, 6.
  • the purified air 54 continues to flow to the cryogenic part 7.
  • the low-temperature part may consist of a single cold box, in which all cryogenic apparatuses are arranged, in particular the one or more heat exchangers and the distillation column (s), or from a variety of separate cold boxes.
  • a cylindrical rectification box 9 contains the distillation columns 9a, here a double column with high-pressure and low-pressure column and a main capacitor arranged therebetween.
  • the remaining cold parts, in particular the main heat exchanger 8a are housed in a cuboid heat exchanger box 8.
  • the two cold boxes 8, 9 insulate the respective cold parts of the apparatus against heat from the environment.
  • a transition section 10 also belongs to the low-temperature part. He is also surrounded by a coldbox; Alternatively, located in the transition section 10 piping and fittings are thermally insulated by means of a correspondingly smaller cold box.
  • the main heat exchanger is designed as exclusively recuperative heat exchanger, so not as a switchable heat exchanger (Revex). It consists, for example, of one block or a plurality of flow-connected blocks.
  • the block or blocks are preferably designed as aluminum plate heat exchangers.
  • Possible further heat exchangers, such as one or more subcooling countercurrents, may also be accommodated in the heat exchanger box; alternatively or additionally, one or more blocks of subcooling countercurrents may be arranged in the rectification box.
  • the form of the rectification box may differ from the exemplary embodiment; For example, it may be substantially cuboidal.
  • the main air compressor 2 is driven via a first shaft 11 by a drive means 12, which is designed as an electric motor, gas or steam turbine.
  • a booster 14 is provided for a portion of the purified air 54.
  • the inlet of the booster 14 is connected to the pipe 54 for the purified air.
  • the further compressed air in the booster 14 is passed through a further, not shown in the drawing pipe in the cryogenic part 7, in particular in the heat exchanger box 8.
  • the booster 14 is also driven by a further shaft 13 of the drive means 12.
  • the booster could be driven independently of the main air compressor, for example by a separate gas or steam turbine or by a separate electric motor.
  • the products of the low-temperature part 7 are discharged via exemplary product lines 105, 106, which open here into manifolds 107 and 108, respectively.
  • the manifolds 107, 108 are arranged on a pipe bridge 109 and can connect the device and possibly other identical or similar devices (strands) to a multi-strand system or lead to a tank farm and / or to an emergency supply device.
  • an evaporative cooler 15 For cooling water before its introduction into the direct contact cooler 3, an evaporative cooler 15 is used. In it, dry residual nitrogen from the low-temperature part is brought into direct heat and mass transfer with cooling water to be cooled. About the cooling water piping 61 cold cooling water is passed to the direct contact cooler. Warm cooling water is returned directly or indirectly to the evaporative cooler. The moist nitrogen from the evaporative cooler reaches the atmosphere.
  • the apparatus also includes utility piping 63, the location of which is schematically indicated in the drawing.
  • the equipment piping serves to transport steam, gas and / or cooling water and to dispose of condensate, cooling water, etc. It flows into resource headers (not shown), which can be arranged on the pipe bridge 109.
  • Resource and booster air tubing 63, 62 may be located on the floor (on sleepers) or on one or more pipe bridges.
  • the base surfaces of the direct contact cooler 3, the cleaning device 4 and the low-temperature part 7 have in the embodiment circular, rectangular or a complex shape. These bases are arranged in a line, for example on a main orientation axis 101. In addition, this line 101 extends through the base of the main air compressor 2. This results in a particularly short Eirisatzgasverrohrung 52/53/54. Also, the product lines 105, 106, which are arranged opposite the entrance of the insert line 54, have a particularly short length. They can even be so short that their own pipe bridge is not needed.
  • the rectangle 102 which encloses the bases of direct contact cooler 3, cleaning device 4 and low-temperature part 7, is approximately 1.7 times longer in the extent that extends vertically in the drawing than in the direction perpendicular thereto (horizontally in the drawing).
  • a factor of about 1.8 applies for the rectangle 103, which also encloses the base of the main air compressor and the apparatuses connected to it.
  • a short pipe bridge 109 and short lines 107, 108 of sufficient length for the product removal or the resource supply and removal; This is particularly advantageous in multi-strand systems. (Due to its schematic character, the drawing is not necessarily to scale in this respect either.)
  • direct contact coolers 3 and evaporative coolers 15 are arranged as a unit or at least as immediately adjacent units because of their functional relationship. In the embodiment, however, the evaporative cooler 15 is much closer to the low temperature part than the direct contact cooler.
  • the distance 104 between the evaporative cooler 15 and the main heat exchanger 8a is about one fifth of the distance between the direct contact cooler 3 and the low temperature part 7.
  • the residual nitrogen pipe between the main heat exchanger and the evaporative cooler 15 which is not shown in the drawing, only a relatively short Overcome route and can therefore be realized particularly cost effective; This saving is significant because of the very large cross-section of the residual nitrogen pipe.
  • the cooling water piping is longer, but has a much smaller cross-section and increases the cost of the apparatus only insignificantly.
  • Cryogenic air separation plants regularly have one or more expansion machines, which serve to generate cold by work-performing relaxation of one or more process streams and are usually designed as turbines.
  • the plant of the embodiment preferably has a turbine for work-performing expansion of a partial flow of the feed air or a product or intermediate product stream from the low-temperature decomposition. This turbine is seated in a turbine box 16, which is arranged in the embodiment at the transition section 10 between the heat exchanger box 8 and rectification box 9.
