The present invention relates to a method of separating and recovering NGLs from a natural gas feedstream. Specifically, the present method allows for the separation of ethane and heavier hydrocarbons and/or propane and heavier hydrocarbons from a raw natural gas feedstream to provide pipeline quality natural gas. One embodiment of this method provides for the use of a regenerable adsorbent media which is regenerated by a microwave heating system. Said regeneration step may be operated as a batch process, a semi-continuous process, or a continuous process.
