| 摘要 |
The present invention relates to a treating system for boil off gas using the expansion energy of gas, comprising: a liquefied gas storage tank in which liquefied gas is accommodated; a liquefied gas supply line which transfers the gas from the liquefied gas storage tank; a boil off gas supply line which transfers a first BOG generated by being connected to the liquefied gas storage tank; a vaporization unit which increases the pressure of the gas transferred from the liquefied gas storage tank and evaporates the gas by being connected to the liquefied gas supply line; a vaporized gas supply line which transfers the vaporized gas to a destination location by being connected to the vaporization unit; and a pressure control unit which is connected to the vaporized gas supply line and the boil gas off supply line, reduces the pressure of the gas passing through the vaporized gas supply line and increases the pressure of the first BOG passing through the boil off gas supply line. |
