Abstract
Disclosed herein is a natural gas liquefaction process using a single refrigeration cycle adopting a mixed refrigerant, and therefore having a simple structure and thus a compact system which is easy to operate, and further, after the mixed refrigerant is separated into two refrigerant parts, the two refrigerant parts are not mixed with each other but go through condensing (cooling), expanding, heat-exchanging, and compressing stages individually, and thus, optimal temperature and pressure conditions are applied to each of the separated refrigerant parts to increase efficiency of the liquefaction process.
