Abstract: front page image
(EN)A target gas contained in a gaseous fluid comprising gas components is efficiently concentrated while avoiding apparatus size increase and apparatus constitution complication. When the first gas contained in a gaseous fluid comprising a first gas and a second gas is concentrated, an adsorbent which adsorbs the second gas is disposed in an adsorption chamber where the first gas contained in the gaseous fluid is concentrated. After the gaseous fluid is introduced into the adsorption chamber, the volume of the adsorption chamber is reduced to thereby increase the pressure of the gaseous fluid and hence increase the amount of the second gas adsorbed onto the adsorbent. The resultant oxygen-enriched gas is taken out. Thereafter, the volume of the adsorption chamber is increased to release the nitrogen which has been adsorbed on the adsorbent and thereby regenerate the adsorbent.
(FR)L'invention permet de concentrer efficacement un gaz cible contenu dans un fluide gazeux comportant des composants gazeux tout en évitant un accroissement de la taille de l'appareil et une complication de sa construction. Lorsque le premier gaz contenu dans un fluide gazeux comportant un premier gaz et un deuxième gaz est concentré, un adsorbant qui adsorbe le deuxième gaz est disposé dans une chambre d'adsorption où le premier gaz contenu dans le fluide gazeux est concentré. Après que le fluide gazeux est introduit dans la chambre d'adsorption, le volume de la chambre d'adsorption est réduit pour augmenter ainsi la pression du fluide gazeux et donc augmenter la quantité du deuxième gaz adsorbé sur l'adsorbant. Le gaz résultant enrichi en oxygène est extrait. Ensuite, le volume de la chambre d'adsorption est augmenté pour libérer l'azote qui a été adsorbé sur l'adsorbant et régénérer ainsi l'adsorbant.
(JA) 複数のガス成分を含むガス流体から目的ガスを濃縮する際に、装置の大型化や構成の複雑さを防ぎながら効率的に目的ガスを濃縮する。  第1ガスと第2ガスとを含むガス流体中から第1ガスを濃縮する場合には、ガス流体中の第1ガスを濃縮する吸着室内に第2ガスを吸着する吸着剤を配置し、吸着室内にガス流体が導入した後に吸着室の容積を減少させることによりガス流体の圧力を増加して吸着剤への第2ガスの吸着量を増加させて残った濃縮された酸素を含むガスを取り出した後、吸着室の体積を増加して吸着剤に吸着した窒素を脱離させて吸着剤を再生する。
