본 발명에 따른 천연가스 액화공정은, 혼합 냉매를 채용한 한 개의 폐 루프 냉동 사이클을 이용하기 때문에 액화공정의 구조가 단순하고 액화공정의 운전이 용이할 뿐만 아니라, 한 개의 스트림이 두 개의 스트림으로 분리된 다음에 각각 천연가스를 냉각시키기 때문에 액화공정의 효율도 우수하다. A natural gas liquefaction process according to the present invention uses a single closed-loop refrigeration cycle employing a mixed refrigerant, thereby having a simple structure for the liquefaction process and allowing the liquefaction process to be easily operated. Furthermore, the present invention cools natural gas after one stream is separated into two streams, thereby having an excellent efficiency of the liquefaction process.
