Abstract
A method is disclosed for the separation of ethane and heavier hydrocarbons or propane and heavier hydrocarbons from natural gas to provide a methane-rich natural gas stream and less volatile natural gas liquids (NGLs). This method provides for passing a natural gas feedstream though a regenerable adsorbent media which adsorbs the NGLs to provides the methane rich natural gas product. The regenerable adsorbent media of the present invention is a cross-linked macroporous polymeric adsorbent media.
