The present invention relates to a pressure control system and a pressure control method of a liquefied gas storage tank, which can prevent the sharp increase of the internal pressure of a liquefied gas storage tank due to the thermal expansion of the evaporation gas in the liquefied gas storage tank. A pressure control system of a liquefied gas storage tank, according to the present invention, comprises: a liquefied gas storage tank provided in a ship and storing liquefied gas; and an evaporation gas recovery line for supplying the evaporation gas generated in the liquefied gas storage tank as fuel, wherein the evaporation gas recovery line includes: an evaporation gas condenser for condensing at least a part of the evaporation gas; and a fuel supply device for supplying the gas uncondensed by the evaporation gas condenser to the ship as fuel.

    본 발명은 액화가스 저장탱크에서 증발가스의 열 팽창에 의해 액화가스 저장탱크의 내압이 급격하게 상승하는 것을 방지할 수 있는 액화가스 저장탱크의 압력 제어 시스템 및 압력 제어 방법에 관한 것이다. 본 발명에 따른 액화가스 저장탱크의 압력 제어 시스템은 선박에 마련되며 액화가스를 저장하는 액화가스 저장탱크; 및 상기 액화가스 저장탱크에서 발생하는 증발가스를 연료로써 공급하는 증발가스 회수라인;을 포함하고, 상기 증발가스 회수라인에는, 상기 증발가스의 적어도 일부를 응축시키는 증발가스 응축기; 및 상기 증발가스 응축기에서 응축되지 않은 기체를 상기 선박의 연료로 공급하는 연료 공급 장치;가 마련되는 것을 특징으로 한다.
