Definitions
- the monograph by Hausen and Linde also describes the cleaning of the feed air for such an air separation plant by means of a thermally regenerated molecular sieve in at least two containers.
- There impurities are removed from the air, which could hinder the cryogenic decomposition, especially water and carbon dioxide, possibly also other substances such as ethylene and nitrous oxide.
- the other can be regenerated by means of a Regeneriergasstroms heated to at least 100 ° C, preferably 150 to 200 0 C.
- the regeneration gas used is normally a pressureless residual gas from the low-temperature decomposition, for example impure nitrogen from the low-pressure column of a two-column system.

Abstract
L'invention concerne un procédé pour analyser la température de l'air, selon lequel un flux d'air (quantité d'air 2) se comprime dans un compresseur d'air, au moins une partie de ce flux d'air comprimé étant purifié dans un dispositif de nettoyage, au moins une partie de cet air purifié étant refroidi, au moins une partie de cet air refroidi étant introduit comme flux d'utilisation (quantité d'air 1) dans un système à colonnes de distillation et au moins un flux de produit (produit GOX 2) étant exploité dans le système à colonnes de distillation et au moins utilisé en partie comme le premier produit fini (produit GOX 1). Le dispositif de purification comprend au moins deux récipients, qui peuvent fonctionner de manière cyclique. Un cycle comporte une phase de chargement, une phase de régénération thermique, et une phase d'accumulation de la pression. Pendant la phase d'accumulation de la pression, une partie du flux d'air comprimé est dirigé vers le récipient correspondant du dispositif de purification. Avant le début de la phase d'accumulation de la pression, le flux d'air d'utilisation est introduit dans le volume de la quantité d'utilisation dans le système à colonnes de distillation. Pendant la phase d'accumulation de la pression, ledit flux d'air d'utilisation est introduit dans le volume d'une seconde quantité d'utilisation, qui est inférieure à la première quantité d'utilisation, dans le système à colonnes de distillation. Le flux de produits est introduit dans un récipient tampon et le flux de produit fini est extrait de ce récipient. Avant le début de la phase d'accumulation de la pression, le flux de produit est extrait d'une partie d'une première quantité de produit hors du système à colonnes de distillation et le produit fini est extrait du récipient tampon dans une première quantité de décharge. Pendant la phase d'accumulation de la pression, le flux de produit est extrait du système à colonnes de distillation dans une quantité qui est plus petite que la première quantité, et une seconde quantité de produit fini est extraite du tampon. La relation entre la seconde quantité et la première quantité est supérieure à la relation entre la seconde quantité de produit et la première quantité de produit.
