Abstract

La présente invention concerne un procédé et un dispositif servant à générer un produit gazeux sous pression contenant de l'oxygène par fractionnement cryogénique de l'air dans un système à colonnes de distillation comportant au moins une colonne de séparation. De l'air d'alimentation est comprimé dans un compresseur d'air. Un premier courant (2, 4, 6, 7) de l'air d'alimentation comprimé est détendu (5, 8), fournissant ainsi une capacité de travail. Un second courant (3) de l'air d'alimentation comprimé (1) est refroidi et liquéfié ou pseudo-liquéfié et ensuite introduit dans le système à colonnes de distillation. Un courant de produit liquide contenant de l'oxygène (51) est extrait du système à colonnes de distillation, amené, à l'état liquide, à une première pression augmentée (52), vaporisé ou pseudo-vaporisé à cette première pression augmentée, par échange de chaleur indirect (10) avec le second courant (3) de l'air d'alimentation comprimé, réchauffé à peu près à température ambiante (10) et enfin extrait sous forme de courant de produit gazeux (55). Le courant de produit contenant de l'oxygène (53) vaporisé ou pseudo-vaporisé est ensuite amené, dans un compresseur à froid (13), à une seconde pression augmentée, supérieure à la première pression augmentée. Le courant de produit (54) est chauffé (10) à peu près à température ambiante, à cette seconde pression augmentée. Au moins une partie de l'énergie mécanique produite lors de la détente (5, 8), fournissant une capacité de travail, du premier courant (3) est utilisée pour actionner le compresseur à froid (13).
