During the storage of various volatile liquids, some of the liquid evaporates due to energy 
from outside the storage environment, which sometimes causes pressure to rise within the 
storage tank or reservoir. In Korea, there are many cases in which liquefied gases such as 
LPG (butane, propane) are imported as fuel and transported from a shipping vessel to a 
storage base on land. In many of these cases, vaporized gas cannot be transferred to the
storage tank because the pressure inside of the storage tank or base has risen to an 
unsafe level. In this case, the Condensing Ejector can be used to condense the gas and 
efficiently transfer the LPG from the shipping vessel to the storage base without any 
additional power or equipment.
