Zusammenfassung:The present disclosure relates to a method for removing carbon dioxide from hydrocarbons, the method comprising the steps of: (a) contacting a feed stream comprising hydrocarbons and carbon dioxide with one or more gas-separation membranes to produce a hydrocarbon-rich retentate gas stream and a permeate gas stream rich in carbon dioxide, the retentate gas stream containing less carbon dioxide relative to the feed stream; and (b) passing at least one of the retentate gas stream or the permeate gas stream through an absorption unit to produce a hydrocarbon-rich gas phase and a liquid absorbent phase containing said carbon dioxide. The present disclosure also relates to a system for doing the same.
