Abstract
A process is described for processing an inert-rich natural gas stream with a lean oil physical solvent to obtain a specification-grade inert gas product, and a specification-grade hydrocarbon gas product, preferably in combination with an existing absorber plant. The process is an adaptation of the extractive flashing and extractive stripping versions of the Mehra Process.
