Abstract:
Disclosed is an improved process for recovering condensable components from a gas stream, in particular, heavier hydrocarbons from a gas stream. The present process uses solid adsorbent media to remove said heavier hydrocarbons wherein the adsorbent media is regenerated in a continuous fashion in a continuous adsorbent media counter-current regeneration system using a stripping gas to provide a regenerated adsorbent media and a product gas comprising heavier hydrocarbons from a loaded adsorbent media. The improvement is the use of a portion of the product gas from the regeneration unit as the stripping gas.
