SEPARATION OF IMPURITIES FROM A HYDROCARBON-CONTAINING GAS STREAM
A process includes contacting a feed stream of light hydrocarbons and an acid gas with a first solvent stream to produce a first methane-enriched overhead gas stream and a first stage solvent effluent bottoms stream including absorbed methane and absorbed acid gas. The process further includes flash...

| description | A process includes contacting a feed stream of light hydrocarbons and an acid gas with a first solvent stream to produce a first methane-enriched overhead gas stream and a first stage solvent effluent bottoms stream including absorbed methane and absorbed acid gas. The process further includes flash separating the first stage solvent effluent bottoms stream to produce a vapor fraction including the acid gas and methane a gas-depleted liquid fraction of the first stage solvent effluent bottoms stream. The process further includes contacting the first methane-enriched overhead gas stream with a second solvent stream to produce a second methane-enriched overhead gas stream and a second stage solvent effluent bottoms stream including absorbed methane CO2. Still further, the process includes regenerating the second stage solvent effluent bottoms stream to produce a vapor fraction comprising the acid gas and a regenerated liquid fraction of the second stage solvent effluent bottoms stream. |
