초록

The present invention is directed to an improved integrated process for the removal of heavy hydrocarbons, carbon dioxide, hydrogen sulfide, and water from a raw natural gas feed stream. More specifically, the integrated process of the present invention comprises a three step process involving the adsorption of heavy hydrocarbons and water on an adsorbent bed selective for the same, a subsequent aqueous lean amine treatment for the absorptive removal of acid gases, such as carbon dioxide and hydrogen sulfide, and an adsorptive removal of water. The proce...

What is claimed is: 1. A process for the purification of a raw natural gas feed stream, wherein said process comprising the steps of: (1) passing said raw natural gas feed stream through an adsorbent unit containing an adsorbent, said adsorbent selective for removal of heavy hydrocarbons and water from said natural gas feed stream, and thereby forming a first effluent stream; (2) passing said first effluent stream in contact with an aqueous amine absorbent, wherein said aqueous amine absorbent removes acid gases from said first effluent stream thereby f...
