Disclosed is an apparatus for treating a boil-off gas. The apparatus for treating the boil-off gas according to an embodiment of the present invention includes: a boil-off gas supply line providing the boil-off gas in a storage tank to a boil-off gas consuming unit; a compression part which is comprised in the boil-off gas supply line, and pressurizes the boil-off gas; a re-liquefaction line which is branched from the boil-off gas supply line, and re-liquefies the boil-off gas flowing by being branched; a re-liquefaction expansion part which expands the boil-off gas flowing into the re-liquefaction line while being comprised in the re-liquefaction line; and a heat exchanging part which exchanges heat between the boil-off gas passing through the re-liquefaction expansion part and the boil-off gas at a front of the compression part of the boil-off supply line. The re-liquefaction expansion part is prepared to make different expansion of the boil-off gas flowing by being branched from the boil-off gas supply line, and is prepared to control pressure of the boil-off gas entering the heat exchanging part.

    증발가스 처리장치가 개시된다. 본 발명의 실시예에 의한 증발가스 처리장치는 저장탱크 내 증발가스를 증발가스 소비수단으로 제공하는 증발가스 공급라인과, 증발가스 공급라인에 구비되고 증발가스를 가압하는 압축부와, 증발가스 공급라인으로부터 분기되고 분기되어 흐르는 증발가스를 재액화하는 재액화라인과, 재액화라인에 구비되어 재액화라인으로 유입되는 증발가스를 팽창시키는 재액화 팽창부와, 재액화 팽창부를 통과한 증발가스와 증발가스 공급라인의 압축부 전단의 증발가스를 열교환시키는 열교환부를 포함하고, 재액화 팽창부는 증발가스 공급라인으로부터 분기되어 흐르는 증발가스의 팽창 정도를 달리할 수 있도록 마련되어, 열교환부에 진입하는 증발가스의 압력을 조절할 수 있도록 마련된다.
