The purpose of the present invention is to provide a system to process a liquefied gas, capable of effectively controlling a pressure when the system supplies a fuel to a low pressure engine requiring low pressure and a high pressure engine requiring high pressure at the same time. According to an embodiment of the present invention, the system to process a liquefied gas comprises: a liquefied gas line connected from a liquefied gas storage tank to a place requiring high pressure; a re-condenser arranged in the liquefied gas line; an evaporated gas line connected from the liquefied gas storage tank to a place requiring low pressure by including a first line connected from the liquefied gas storage tank to the re-condenser and a second line connected from the re-condenser to the place requiring low pressure; and a detour line connected to the second line or the place requiring low pressure by detouring the re-condenser in the first line. An evaporated gas supplied from the first line to the re-condenser is blocked and the detour line is opened when the place requiring high pressure and the place requiring low pressure are operated at the same time. According to the present invention, the system to process a liquefied gas may individually control a fuel supplied to the place requiring lower pressure and the place requiring high pressure by blocking the evaporated gas supplied from the first line to the re-condenser and by opening the detour line when the place requiring low pressure and the place requiring high pressure are operated at the same time because control over the level or pressure of the re-condenser depending on a load change of the place requiring low pressure and the place requiring high pressure is difficult.

    본 발명의 일 실시예에 따른 액화가스 처리 시스템은, 액화가스 저장탱크에서 고압 수요처까지 연결되는 액화가스라인; 상기 액화가스라인 상에 마련되는 재응축기; 상기 액화가스 저장탱크에서 상기 재응축기까지 연결되는 제1 라인을 포함하고, 상기 재응축기에서 저압 수요처까지 연결되는 제2 라인을 포함하여, 상기 액화가스 저장탱크에서 저압 수요처까지 연결되는 증발가스라인; 및 상기 제1 라인에서 상기 재응축기를 우회하여 상기 제2 라인 또는 상기 저압 수요처에 연결되는 우회라인을 포함하되, 상기 고압 수요처와 상기 저압 수요처가 동시 구동시, 상기 제1 라인으로부터 상기 재응축기로 공급되는 증발가스는 차단되고, 상기 우회라인이 개방되는 것을 특징으로 한다. 본 발명에 따른 액화가스 처리 시스템은, 저압 수요처와 고압 수요처의 로드 변화에 따라 재응축기의 레벨이나 압력 조절이 어려우므로, 저압 수요처와 고압 수요처가 동시에 구동되는 경우, 제1 라인으로부터 재응축기로 공급되는 증발가스를 차단하고 우회라인을 개방시켜 저압 수요처와 고압 수요처로 공급되는 연료를 개별로 제어할 수 있어, 시스템 제어가 용이하다.
