Abstract

L'INVENTION CONCERNE UN ENSEMBLE DE SEPARATION COMPRENANT UN PREMIER LIT D'ADSORPTION, UN LIT D'ADSORPTION SUPPLEMENTAIRE, DES MOYENS RELIANT A UN COURANT GAZEUX D'ALIMENTATION LES ENTREES DE GAZ DU PREMIER LIT ET DU LIT SUPPLEMENTAIRE, ET UNE SORTIE DE PRODUIT. CET ENSEMBLE COMPREND UNE CONDUITE DE SORTIE PERMETTANT DE COUPLER A LADITE SORTIE DE PRODUIT LES ENTREES DE GAZ DU PREMIER LIT ET DU LIT SUPPLEMENTAIRE, UN RESERVOIR 84, UNE PREMIERE CONDUITE 86, 92, 90 DE RESERVOIR QUI RELIE LA CONDUITE DE SORTIE 74 AU RESERVOIR 84 ET COMPORTE UN MOYEN 90 N'AUTORISANT LE PASSAGE DU GAZ QUE DANS UN SEUL SENS, DE LA CONDUITE DE SORTIE 74 AU RESERVOIR 84, ET UNE SECONDE CONDUITE 86, 96 DE RESERVOIR QUI RELIE LE RESERVOIR 84 A LA CONDUITE DE SORTIE 74 ET COMPORTE UNE SOUPAPE 96 COMMANDANT LE PASSAGE, DU RESERVOIR 84 A LA CONDUITE DE SORTIE 74, DU GAZ PRODUIT. UNE APPLICATION EST L'OBTENTION DE GAZ D'UNE GRANDE PURETE.THE INVENTION RELATES TO A SEPARATION ASSEMBLY COMPRISING A FIRST ADSORPTION BED, AN ADDITIONAL ADSORPTION BED, MEANS CONNECTING TO A GAS CURRENT SUPPLY THE GAS INPUTS OF THE FIRST BED AND THE ADDITIONAL BED, AND AN OUTLET OF PRODUCT . THIS ASSEMBLY INCLUDES AN OUTLET DUCT ALLOWING TO COUPLING THE GAS INPUTS OF THE FIRST BED AND THE SUPPLEMENTARY BED TO THE SUCH PRODUCT OUTLET, A TANK 84, A FIRST DUCT 86, 92, 90 FROM THE TANK THAT CONNECTS THE OUTLET DUCT 74 TO THE RESERVOIR 84 AND INCLUDES A MEANS 90 AUTHORIZING THE PASSAGE OF GAS ONLY IN ONE DIRECTION, FROM THE OUTLET PIPE 74 TO TANK 84, AND A SECOND PIPE 86, 96 OF TANK THAT CONNECTS TANK 84 TO THE OUTLET PIPE 74 AND INCLUDES A VALVE 96 CONTROLLING THE PASSAGE, FROM TANK 84 TO OUTLET LINE 74, OF THE GAS PRODUCED. ONE APPLICATION IS THE OBTAINING OF HIGH PURITY GAS.
