Gas dehydration process

Abstract

Abstract Translated from French PROCEDE DE DESHYDRATATION D'UN GAZ CONTENANT DES HYDROCARBURES PAR PERMEATION A TRAVERS UNE MEMBRANE PRESENTANT UNE PERMEABILITE AU METHANE D'AU MOINS 10 CMCM-S-CM HG, ET UN FACTEUR DE SELECTIVITE DE L'EAU PAR RAPPORT AU METHANE SUPERIEUR A 100 ENVIRON, DANS LEQUEL LA MEMBRANE 4 EST CONSTITUEE PAR UN FAISCEAU DE FIBRES CREUSES OUVERTES AUX DEUX EXTREMITES, DE DIAMETRE INTERNE COMPRIS ENTRE 0,1 MM ET 0,5 MM ET D'UNE EPAISSEUR COMPRISE ENTRE 0,05 MM ET 0,3 MM, L'EPAISSEUR DE LA SEULE COUCHE ACTIVE ETANT INFERIEURE A 1 MM, QUI SONT TRAVERSEES DE L'EXTERIEUR A L'INTERIEUR PAR LA PORTION DE GAZ QUI PERMEE. PROCESS FOR DEHYDRATION OF A GAS CONTAINING HYDROCARBONS BY PERMEATION THROUGH A MEMBRANE WITH A PERMEABILITY TO METHANE OF AT LEAST 10 CMCM-S-CM HG, AND A SELECTIVITY FACTOR OF WATER WITH RESPECT TO METHANE OF MORE THAN ABOUT 100 , IN WHICH MEMBRANE 4 IS CONSTITUTED BY A HOLLOW FIBER BEAM OPEN AT BOTH ENDS, WITH AN INTERNAL DIAMETER BETWEEN 0.1 MM AND 0.5 MM AND A THICKNESS BETWEEN 0.05 MM AND 0.3 MM, THE THICKNESS OF THE SINGLE ACTIVE LAYER BEING LESS THAN 1 MM, WHICH ARE CROSSED FROM THE EXTERIOR TO THE INSIDE BY THE GAS PORTION WHICH PERMEED.
