Abstract
A process for treatment of a natural gas stream, or other methane containing stream that passes through a guard bed for removal of mercury and hydrolysis of COS, followed by treatment with an absorbent unit containing an amine solvent for removal of carbon dioxide and hydrogen sulfide. The gas is then dried by a molecular sieve bed. The regeneration gas for the molecular sieve adsorbent bed is chilled to remove liquid hydrocarbons and sulfur compounds. The process is accomplished without the use of an absorbent unit to remove the sulfur compounds.
