At economic aspect and importantly avoiding aspect the environment or reducing discharging from the cold-producing medium of many refrigerant cools system in conjunction with the adjusting of the composition of refrigerant mixture.Therefore, can be stored in (multiple) flow point that extracts in the step a) one or more separately, all preferred.Store the flow point that extracts individually and help other processing, for example the flow point that extracts is reclaimed or recycles.Can discard (for example diffusing away (flare off)) not any flow point of storage.Typically can discard but not store the flow point that extracts, if this flow point undesirable words on purity.
In order not only to avoid or reduce the discharging of cold-producing medium, but also realize the end (closing) of expectation of the operation of many refrigerant cools process, the cold-producing medium stream of supplying in step b) can comprise one or more in (multiple) flow point of storage, preferably is made up of in (multiple) flow point of storage one or more.Therefore, (multiple) flow point that extracts from many refrigerant cools system can turn back to many refrigerant cools system, but so that amount and/or ratio that the composition of the refrigerant mixture of many refrigerant cools system changes.Be not from many refrigerant cools system, extract but typically be fed to many refrigerant cools system aptly in pure mode or with the part that the additional cold-producing medium (Make-up refrigerant) of the mixture supply of the composition set can be used as the cold-producing medium stream of step b) basically.
Typically, the operation of many refrigerant cools system comprises inherently and its refrigerant mixture is separated into fully (at large) different flow point corresponding to the corresponding cold-producing medium of refrigerant mixture.Therefore, valuably, the quantity of the flow point that extracts in step a) can be equal to or less than, preferably equal the quantity of the cold-producing medium in the refrigerant mixture of many refrigerant cools system.
Once in a while, can be useless is any flow point that extracts of storage refrigerant mixture, can be discarded in (multiple) flow point that extracts in the step a).As mentioned above, can diffuse away such (multiple) flow point.Can be one the reasonable quantity of the flow point that in step a), extracts in this case.But, but not from many refrigerant cools system, to extract typically basically in pure mode or with the part that the additional cold-producing medium of the mixture supply of the composition set can be used as the cold-producing medium stream of step b) to be fed to many refrigerant cools system.
The storage (a plurality of) flow point can remain on separately be in many refrigerant cools system such position (promptly, corresponding flow point is extracted in such position in step a)) pressure of the refrigerant mixture located and being under the pressure between the pressure of the refrigerant mixture of such position (that is, step b) is carried out in such position) of many refrigerant cools locating.Alternatively or additionally, such position of each comfortable many refrigerant cools system of (multiple) flow point that extracts in step a) is extracted, that is, in this position refrigerant mixture than at execution in step b) time the position of many refrigerant cools system be under the higher pressure.As the favourable outcome of as this paper suggestion, considering the pressure aspect, can be under the situation that does not have pump or other pressure regulating device, perhaps under the situation that still less needs pump or other pressure regulating device, can carry out the storage of the extraction of (multiple) flow point of refrigerant mixture, such (multiple) flow point and/or the supply of cold-producing medium stream.
