摘要： In order to provide for the drawing off of residual vapors of a low boiling liquid from a pressure system into a storage vessel, the pressure between the system and the storage vessel is first equalized, whereafter the pressure in the storage vessel is reduced and the pressure in the pressure system increased, thereby enabling passage of the low boiling liquid, and its associated vapors in the liquid state, into the storage vessel. This process can be repeated in order to draw off all liquid with its vapors from the pressure system.
