Abstract

The present invention relates to a natural gas liquefaction process, which involves pre-cooling natural gas using a closed-loop pre-cooling cycle, and liquefying the pre-cooled natural gas using a closed-loop liquefying cycle. The closed-loop pre-cooling cycle includes first and second pre-cooling cycles, which cooperate with one another to pre-cool the supplied natural gas in the same first heat exchange region using pure refrigerants with which said pre-cooling cycles are respectively provided. The closed-loop liquefying cycle includes at least one liquefying cycle for liquefying the pre-cooled natural gas using a mixed refrigerant. The first and second pre-cooling cycles are closed-loop refrigerating cycles.
