SYSTEM AND METHOD FOR DELIVERING A FLUID STORED IN LIQUEFIED FORM TO AN END USER IN GASEOUS FORM

摘要

A system and method is disclosed for storing a fluid in a storage vessel in liquefied form and delivering it in gaseous form to an end user through a supply line. The system comprises a pressure relief circuit for returning the fluid from the supply line to the vessel when predetermined conditions are met.
