Title (EN) NATURAL GAS LIQUEFACTION PROCESS
(FR) PROCÉDÉ DE LIQUÉFACTION DE GAZ NATUREL
(KO) 천연가스 액화공정
Abstract: front page image
(EN)The present invention relates to a natural gas liquefaction process which is simple because of comprising one freezing cycle, thereby enabling compactness of a system and easy operation of a liquefaction system, and has excellent natural gas liquefaction efficiency by precisely separating a refrigerant into a heavy key portion and a light key portion in the required composition through a separation means, precooling natural gas with one refrigerant flow in a first heat exchange area, and liquefying natural gas with the other refrigerant flow in a second heat exchange area.
(FR)La présente invention concerne un procédé de liquéfaction de gaz naturel, qui est simple en ce qu'il comprend un seul cycle de réfrigération, ce qui permet d'obtenir un système de liquéfaction compact et facile à exploiter. Le procédé assure une excellente efficacité de liquéfaction de gaz naturel en ce qu'il permet: d'utiliser un moyen de séparation pour séparer avec précision un fluide frigorigène en une partie principale lourde et une partie principale légère, dans la composition requise; de prérefroidir le gaz naturel avec un flux de fluide frigorigène dans une première zone d'échange de chaleur, et de liquéfier le gaz naturel avec l'autre flux de fluide frigorigène dans une seconde zone d'échange de chaleur.
(KO)본 발명은 하나의 냉동 사이클로만 이루어지기 때문에 액화공정이 단순하여 시스템이 콤팩트하고 액화시스템의 운전이 용이하면서도, 분리 수단을 통해 요구되는 조성으로 정밀하게 냉매를 헤비 키 부분과 라이트 키 부분으로 분리한 다음, 하나의 냉매 흐름으로는 제1 열교환 영역에서 천연가스를 예냉시키고, 다른 하나의 냉매 흐름으로는 제2 열교환 영역에서 천연가스를 액화시키기 때문에 천연가스의 액화 효율이 우수한 천연가스 액화공정에 관한 것이다.
