Abstract

Se hace pasar una corriente de gas natural a través de un elemento de una sola membrana que está fabricado con dos o más tipos diferentes de fibras de membrana. Las fibras de membrana tienen diferentes características a fin de reducir la cantidad de elementos de membrana requeridos para la separacion del gas y para mejorar el rendimiento de separacion de gas debido a la composicion del gas cambiante debido a la permeacion a medida que el gas viaja a través del elemento de membrana.
