Processes and systems are provided for recovering a liquid natural gas ('LNG') from a hydrocarbon-containing gas. More particularly, the present invention is generally related to processes and systems that optimize the chilling efficiencies of an LNG facility through the utilization of an auxiliary refrigeration cycle. Additionally, the present invention is also generally related to the rerouting of mixed refrigerants in a closed-loop refrigeration cycle in order to optimize the chilling efficiencies of the LNG facility.

Mixed refrigerant distributed chilling scheme

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.

LNG recovery from syngas using a mixed refrigerant

Processes and systems for producing liquefied natural gas (LNG) with a single mixed refrigerant, closed-loop refrigeration cycle are provided. Liquefied natural gas facilities configured according to embodiments of the present invention include refrigeration cycles optimized to provide increased efficiency and enhanced operability, with minimal additional equipment or expense.

Liquefied natural gas facility employing an optimized mixed refrigerant system

A system and a method for recovering and increasing the pressure of seal leak gas for recycle or passage to further processing.

System and method for collecting and increasing the pressure of seal leak gas

A closed loop single mixed refrigerant process and system wherein the process efficiency is increased by increasing the temperature of liquefied material produced in a heat exchange refrigeration zone and thereafter cooling the liquefied material by flashing a portion of the liquefied material to produce a cooler liquefied material and a flash gas a portion of which is recycled to the heat exchange refrigerator. The process and system provide increased process efficiency and flexibility.
