More Information
Summary:The present invention relates to a temporary storage system for boil-off gas and, more specifically, to a temporary storage system for boil-off gas which removes boil-off gas to reduce the pressure of a fuel liquefied natural gas tank of the subject ship which is in a relatively high pressure state, before refueling the subject ship with a liquefied natural gas, which compresses the boil-off gas into high pressure and temporarily stores the gas in a boil-off gas absorbing tank, and then supplies the gas to a high pressure gas delivering part and a high pressure liquefied natural gas delivering part to reuse the boil-off gas. The temporary storage system not only controls the pressure of the low pressure liquefied natural gas tank and the fuel liquefied natural gas tank of the subject ship, but also does not need a complicated and expensive liquefying apparatus.
