System for treating boil-off gas

Abstract

A boil-off gas treatment system according to the present invention includes: a storage unit in which a liquefied gas is stored; a subcooling unit connected to the storage unit and configured to subcool boil-off gas generated from the liquefied gas stored in the storage unit to generate subcooled boil-off gas; a compression unit connected to the subcooling unit and configured to receive the subcooled boil-off gas from the subcooling unit and compress the subcooled boil-off gas to generate compressed subcooled boil-off gas; and a phase change unit connected to the compression unit, configured to receive the compressed subcooled boil-off gas from the compression unit, and configured to induce a phase change of the compressed subcooled boil-off gas into a liquid/solid-based slush state.
