摘要： The invention relates to a method for conditioning the atmosphere in a storage chamber for organic harvested produce, characterized in that the storage chamber is allowed to form part of a system composed of the relevant storage chamber (1), at least two, and preferably three, gas separation modules (2), (3) and (4), which are located downstream of one another and are provided with N.sub.2 /O.sub.2 separation membranes, at least one compressor (5) and at least one control valve (6),the compressor drawing in three streams (F1), (F2) and (F3),the first separation module yielding a permeate, which is removed from the system as stream (F4), and a retentate, which is fed to the second separation module,the second separation module yielding a retentate, which is fed to the third separation module, and a permeate, which is fed together with the permeate from the third separation module as stream to the compressor, andthe retentate from the third separation module is fed via the control valve to the storage cheer.

摘要： Gas separation apparatus constructed from a module comprising a bundle of asymmetric hollow fibres of poly(2,6-dimethyl-p-phenylene oxide) having the high molecular weight Mw of 10.sup.5 -5.10.sup.6. The hollow fibres in question produced by coagulation spinning consist of a relatively thick porous layer which offers hardly any resistance to gas permeation and a very dense but thin top layer responsible for the actual favorable gas separation achieved.
