APPARATUS FOR RETREATING BOIL OFF GAS

摘要

Disclosed is an evaporation gas processing apparatus for reliquefying evaporation gas generated in a storage tank. According to an embodiment of the present invention, the evaporation gas processing apparatus includes: an evaporation gas processing line which provides the evaporation gas generated from the storage tank storing liquefied gas as an evaporation gas consumption means; a compression unit which is arranged on the evaporation gas processing line to compress and cool the evaporation gas; a reliquefying branch line branching from the evaporation gas processing line; an evaporation gas inlet line which is connected to the storage tank to let the evaporation gas flow therein; an evaporation gas reliquefying line including a evaporation gas return line which reliquefies the evaporation gas flowing in from the evaporation gas inlet line and the reliquefying branch line to return the reliquefied gas to the storage tank; and an ejector which is arranged on the merging part of the reliquefying branch line and the evaporation gas inlet line to use the evaporation gas moving to the evaporation gas return line through the reliquefying branch line to guide the evaporation gas from the storage tank.
