When unloading liquefied propane gas (LPG) ships at very high flow rate into the LPG storage cavern, excessive in-cavity pressure rise  due to vapor generation at high rate.

Condensing ejector used to cope with it and make easier unloading operations.  The purpose of the condensing ejector is to condense of the vapor phase from the storage cavern, utilize into the liquid propane stream being unloading from LPG carrier ship to the cavern.

The cold energy of the LPG is used in the ejector condenser for suction and condense the vapor from cavern.
