PROBLEM TO BE SOLVED: To provide a residual liquefied gas recovery system whose constitution can be simplified. SOLUTION: It constitutes a container for pressurization 3 to store the liquefied gas, a pipeline for pressurization 7 serving as a connection part 7a connected to the side of a container 22 that one end communicates to the gas phase 5 of the container for pressurization 3, and other end is a recovery object of the residual liquefied gas, a heating means 9, 23 for raising the pressure in the container for pressurization 3 by heating the liquefied gas stored in the container for pressurization 3, a recovery container 11 that recovers the residual liquefied gas, and a pipeline for recovery 13 serving as a connection part 13a connected to the side of a container 22 that one end is connected to the recovery container 11 and other end is the recovery object of the residual liquefied gas. As such constitution, the residual liquefied gas recovery system can be simplified, because it can recover the residual liquefied gas 31 of the liquid phase that is accumulated in the container 22 regarded as the recovery object of the residual liquefied gas without using a conventional complicated piping, valve, compressor etc. COPYRIGHT: (C)2005,JPO&NCIPI
