- the first and second flow rates enter their respective assemblies at different pressures and / or temperatures.
- first and second flow rates are mixed downstream of the first and second assemblies.

- the six exchange bodies can be identical and are standardized exchangers of the same model from a single manufacturer.
- Each exchange body carries out a heat exchange between only two fluids.
- the exchange bodies 13A to 13C are placed one above the other, the 13C being the lowest and the 13A being the highest.
- the exchange bodies 11A to 11C are placed one above the other, the 11C being the lowest and the 11A being the highest.
- Air to be cooled 1 is divided in two by means of two valves 7, 9 to form two flow rates 3, 5.

- the flow 5 is sent to the second assembly constituted by the exchange bodies 13A, 13B, 13C connected in series and is not sent to the first assembly.
- the air flow is not mixed except possibly downstream of the last bodies 11 C, 13C.
- the first and second flow rates enter their respective assemblies at different pressures and / or temperatures, having, for example, been compressed at different pressures.
- a flow of vaporized rich liquid 17 from the condenser of a single column is fed to the bodies 11C, 11B, 11A in order to be heated to room temperature.

- the bodies are placed, in use, one above the other, the 13A being the highest and the 13 E the lowest.
- the bottom body 13 E is leaning because there is a risk of having drops of liquid air output.
- FIG 4 the bodies 11 are arranged as in Figure 1.
- Figure 5 shows a particular arrangement suitable for bodies having an irregular hexagonal section, such as MAXCHANGER ®.
- the bodies 11A, 11B, 11C are arranged one above the other with connecting elements 21 which fill the voids on either side of the bodies to form a generally rectangular section element capped with four inlets / outlets 23.
- This monolithic element is particularly easy to install and support. Even if one has the impression of complicating the arrangement with this type of exchangers, it allows the use of standard exchangers inexpensive and with extremely short manufacturing times: the cryogenic exchangers are then no longer on the critical path of realization of the air separation apparatus.
- Figure 6 shows an air separation apparatus for producing nitrogen comprising an exchange line according to the invention.
