description A method includes: providing a carbon dioxide recycle stream comprising natural gas liquids; separating, using a first distillation tower, the carbon dioxide recycle stream into a first vapor fraction and a first liquid fraction; cooling and partially condensing the first vapor fraction in a heat exchanger to yield a first carbon dioxide stream and a reflux stream; and separating, using a second distillation tower, the first liquid fraction into a second carbon dioxide stream and a natural gas liquids rich stream.
