Abstract
A process is provided to treat a natural gas stream by removing heavier hydrocarbons comprising C5, C6 and heavier hydrocarbons. The process involves sending a natural gas stream through an adsorbent bed to remove heavier hydrocarbons and producing a product stream comprising C1 to C4 hydrocarbons. A portion of the product stream is sent through a regeneration heater to produce a heated regeneration gas stream which is sent through the adsorbent bed to desorb the heavier hydrocarbons. Then the regeneration gas stream is cooled and sent to a separation unit such as a distillation column to divide the regeneration gas stream into a liquid stream comprising heavier hydrocarbons and a recovered regeneration gas stream.
