ABSTRACT:
An apparatus and process for providing purified natural gas wherein a natural gas feed mixture of hydrocarbons, nitrogen, and other permeable gases is provided to a semi-permeable membrane separator having a relatively higher selectivity for methane and other hydrocarbons and a relatively lower selectivity for nitrogen, to thereby provide a gaseous permeate product enriched in hydrocarbons and diminished in nitrogen.
