Abstract
A process is provided for the purification of natural gas wherein the nitrogen content of natural gas is reduced to pipeline specification using a pressure swing adsorption processes with a suitable selective adsorbent for methane purification. More specifically, the present invention relates to the use of a particular combination of steps in the PSA cycle to produce a product natural gas having a reduced nitrogen content, a nitrogen-rich stream and a high heat content fuel gas stream.
