SYSTEM AND METHOD FOR TREATING BOIL-OFF GAS IN SHIP |
摘要 |
Disclosed are a system and method for treating boil-off gas in a ship, which use a portion of gas, which has been discharged from a storage tank and compressed, as fuel for a ship's engine and liquefy the remainder by using the coldness of boil-off gas that is freshly discharged from the storage tank so as to return the remainder to the storage tank, thereby allowing boil-off gas to be efficiently used. The system for treating boil-off gas in a ship according to the present invention comprises: compressing means for receiving and compressing boil-off gas discharged from the storage tank; an intermediate pressure gas engine for receiving at least a portion of boil-off gas from the boil-off gas compressed by the compressing means as fuel; heat exchange means for performing heat exchange on the remaining boil-off gas that has not been supplied as fuel to the intermediate pressure gas engine and boil-off gas that has been discharged from the storage tank and has not been compressed; and expansion means for reducing the pressure of the remaining boil-off gas cooled by the heat exchange means. |
