A liquefaction process according to the present invention primarily cools natural gas in a first heat exchange part by using a single closed loop cooling cycle applying a mixed coolant, and secondarily cools the natural gas in a second heat exchange part distinguished from the first heat exchange part. The subject of the present invention is to provide the natural gas liquefaction process having a simple structure of the liquefaction process, and not only having the liquefaction process easily operated, but also having excellent efficiency of the liquefaction process. 본 발명에 따른 액화공정은, 혼합 냉매를 채용한 한 개의 폐 루프 냉동 사이클을 이용하여 제1 열교환부에서 일차적으로 천연가스를 냉각시키고 상기 제1 열교환부와 구별되는 제2 열교환부에서 이차적으로 천연가스를 냉각시키는 천연가스 액화공정에 관한 것이다.
