Abstract

A natural gas stream is passed through a single membrane element that is fabricated with two or more distinct types of membrane fibers. The membrane fibers have different characteristics in order to reduce the number of membrane elements required for gas separation and to improve gas separation performance due to changing gas composition because of permeation as the gas travels through the membrane element.
