Processes and systems are provided for recovering a liquid natural gas (LNG) stream from a hydrocarbon-containing feed gas stream using a single closed-loop mixed refrigerant cycle. In particular, the processes and systems described herein can be used to separate methane from carbon monoxide and hydrogen, which are common components in synthesis gas and other hydrocarbon-containing gases.
