摘要: An object of the present invention is to provide a pressure swing adsorption gas separation apparatus that can separate strong adsorbate components with high purity without allowing weak adsorbate components to contaminate the strong adsorbate component-storage tank. The present invention provides a pressure swing adsorption gas separation apparatus (100) including a raw material gas-storage tank (1) that stores a mixed gas of a target component and at least one component other than the target component as a raw material gas; a strong adsorbate component-storage tank (2) that stores strong adsorbate components; a weak adsorbate component-storage tank (3) that stores strong adsorbate components; a compressor (4) that compresses a gas of the raw material gas-storage tank (1) or the strong adsorbate component-storage tank (2); a compressor (5) that compresses a gas of the strong adsorbate component-storage tank (3); and four adsorption columns of a lower column (10B), lower column (1 1B), upper column (10U), and upper column (11U).

摘要: Process for the recovery of helium from one or more than one helium-containing off-gas streams by successive preconditioning, cryogenic separation and purification, whereby the off-gas preconditioning takes place a multi-stage preconditioning unit 10, said preconditioning unit 10 comprising n stage units S1 to Sn, with n ≥ 2, each stage unit S1 to Sn being adapted to precondition off-gas by at least partially chemically converting at least one component other than helium in the off-gas and/or by at least partially removing at least one component other than helium from the off-gas, the stage units S1 to Sn being in linear fluid succession so that off-gas which has been preconditioned in stage unit Sx, with 1 ≤ x

摘要: Dans un procédé de séparation d'argon par distillation cryogénique dans lequel un débit (2) contenant de l'argon, de l'oxygène et de l'azote, plus riche en argon que l'air, est envoyé à une colonne de distillation (1),un débit gazeux riche en argon (3) est soutiré en tête de la colonne, une partie du débit gazeux riche en argon (11) est mélangée avec des billes ayant un diamètre inférieur à 5mm pour former un mélange gazeux (15) contenant des billes, les billes étant en matière adsorptive capable d'adsorber de l'oxygène en présence d'argon aux températures d'opération de la colonne, la partie du débit gazeux riche en argon mélangée avec les billes est condensée puis est envoyée en tête de la colonne et un liquide de cuve (19) contenant des billes est soutiré de la colonne et traité pour enlever les billes, les billes enlevées sont régénérées pour enlever l'oxygène adsorbé et sont de nouveau mélangées avec la partie du débit gazeux riche en argon.

摘要: The present invention relates to a method for manufacturing an ophthalmic preparation comprising thymosin β4. According to the inventive method, the manufacture of an ophthalmic preparation comprising thymosin β4 is carried out in the presence of an inert gas, thus the contact of thymosin β4 with oxygen is blocked and the oxidation of thymosin β4 can be prevented and the pharmacological activity of thymosin β4 maintains for long-term period. Therefore, the ophthalmic preparation prepared by the inventive method can maintain the pharmacological activity of thymosin β4 in a stable state for a long time.
