The present invention relates to a system for recovering volatile organic compounds of a crude oil carrier and a method thereof, which allow a carrier using natural gas as fuel and carrying a liquid cargo such as crude oil to liquefy and recover volatile organic compounds generated by a liquid cargo storage tank. To this end, the system for recovering volatile organic compounds of a crude oil carrier according to the present invention is the system for recovering volatile organic compounds of a crude oil carrier that uses natural gas as propellant, which comprises: an LNG carburetor which vaporizes liquefied natural gas into natural gas to supply the same as fuel; a second condenser condensing volatile organic compounds (VOC) generated in a crude oil storage tank by using the natural gas supplied as fuel as a refrigerant; an LVOC storage tank which stores the LVOC condensed by the cold energy of the natural gas; a pre-treatment device which pre-treats the volatile organic compounds supplied to the second condenser to increase the recovery rate of the LVOC; and a combustion device using the liquefied natural gas and the LVOC as fuel.
본 발명은 천연가스를 연료로 사용하고, 원유 등 액체화물을 운반하는 운반선에서, 액체화물 저장탱크로부터 발생한 휘발성 유기화합물을 액화시켜 회수하는 원유 운반선의 유기화합물 회수 시스템 및 방법에 관한 것이다. 본 발명에 따른 원유 운반선의 유기화합물 회수 시스템은, 천연가스를 추진 연료로 사용하는 원유 운반선의 휘발성 유기화합물 회수 시스템에 있어서, 액화천연가스를 연료로 공급하기 위하여 천연가스로 기화시키는 LNG 기화기; 원유 저장탱크에서 생성된 휘발성 유기화합물(VOC)을 상기 연료로 공급되는 천연가스를 냉매로 하여 응축시키는 제2 응축기; 상기 천연가스의 냉열에 의해 응축된 LVOC를 저장하는 LVOC 저장탱크; 상기 LVOC의 회수율을 증가시키기 위하여 상기 제2 응축기로 공급되는 휘발성 유기화합물을 전처리하는 전처리 장치; 및 상기 액화천연가스 및 LVOC를 연료로 사용하는 연소 장치;를 포함한다.
