Abstract
Processes and systems are provided for removing nitrogen from a hydrocarbon-containing gas to thereby recover a liquid natural gas (LNG) stream. In particular, the processes and systems described herein can be used to efficiently separate methane from nitrogen, which is an undesirable byproduct found in many hydrocarbon-containing gases used to produce LNG. The processes and systems described herein can utilize various refrigerant systems to separate and produce the LNG.
