The present invention relates to an evaporation gas treatment system and a ship, comprising: a liquefied gas storage tank; a re-condenser for missing evaporation gas of the liquefied gas storage tank with liquefied gas of the liquefied gas storage tank; and a re-gasifying device for re-gasifying the liquefied gas and the re-condensed evaporation gas to supply to a demand, wherein the re-condenser comprises: a pipe shaped re-condenser in which the liquefied gas flows and the evaporation gas joins; and a tank shaped re-condenser storing the liquefied gas and into which the evaporation gas is introduced. The pipe shaped re-condenser and the tank shaped re-condenser are provided in a serial or a parallel manner on the basis of flow of the evaporation gas. 본 발명은 증발가스 처리 시스템 및 선박에 관한 것으로서, 액화가스 저장탱크; 상기 액화가스 저장탱크의 증발가스를 상기 액화가스 저장탱크의 액화가스와 혼합하여 재응축하는 재응축기; 및 상기 액화가스 및 상기 재응축된 증발가스를 재기화하여 수요처로 공급하는 재기화장치를 포함하고, 상기 재응축기는, 상기 액화가스가 유동하며 상기 증발가스가 합류되는 배관 형태를 갖는 관형 재응축기와, 상기 액화가스가 저장되며 상기 증발가스가 유입되는 탱크 형태를 갖는 탱크형 재응축기를 포함하며, 상기 관형 재응축기와 상기 탱크형 재응축기는, 상기 증발가스의 흐름을 기준으로 직렬 또는 병렬로 마련되는 것을 특징으로 한다.
