Abstract
A natural gas feedstream containing contaminants such as carbon dioxide is purified by passing the contaminated natural gas stream through a membrane to remove the bulk of the contaminant, passing the purified natural gas stream to a TSA unit to remove additional contaminant from the natural gas stream to a desired specification, and regenerating the TSA adsorbent by heating the adsorbent with a heated contaminant-containing permeate stream from the membrane.
