Abstrakt

The article describes processes occurring in a container after releasing pressure and presents various scenarios of a leak. Relations for assessing the proportion of the gas volume (from the container) which escapes into the environment after releasing pressure are given, and relations for the proportion of the liquid volume which rapidly evaporates after releasing pressure due to the heat accumulated in the liquid as overheating above the normal boiling point, The article further specifies relationships for assessing the volume work associated with the gas and vapour expansion after releasing pressure. The data ior assessing the course of evasion of liquefied industrial gases when stored at 20 oC are given in the paper.
