Carbon Dioxide Recycle Stream Processing in an Enhanced Oil Recovery Process

摘要

A method for recovering natural gas liquids from a recycle stream having natural gas liquids includes receiving a carbon dioxide recycle stream that comprises carbon dioxide, natural gas, and the natural gas liquids. The carbon dioxide recycle stream is separated into a purified carbon dioxide recycle stream and a natural gas liquids stream. The purified carbon dioxide recycle stream comprises the carbon dioxide and the natural gas, and the natural gas liquids stream comprises the natural gas liquids. In another embodiment, a system comprises piping and a separator. The piping is configured to receive a recycle stream, and the separator is coupled to the piping and is configured to separate the recycle stream into a purified recycle stream and a natural gas liquids stream.
