Abstract
The invention relates to a method for achieving low oxygen levels in a natural gas stream without the use of a catalytic system. In one embodiment, the method comprises: membrane treatment for the removal of the bulk of CO2 and oxygen in the natural gas feed and the addition of a PSA system using a carbon molecular sieve adsorbent for the adsorption of residual oxygen.
