CRYOGENIC LIQUID CONDITIONING AND DELIVERY SYSTEM

摘要

A cryogenic liquid conditioning system with flow driven by head pressure of liquid contained in a cryogenic storage tank, and a cryogenic liquid delivery system with flow driven by pressure in the vapor space of said cryogenic storage tank. A heat exchanger, coupled to the cryogenic storage tank located below the liquid level of said tank, operates as a portion of both the conditioning system and delivery system. A piping system moves cryogenic liquid to the heat exchanger where it is vaporized, and then moves vaporized liquid to the vapor space of the cryogenic tank and an application. The piping system includes a means for controlling flow through the system. A means for measuring the saturated pressure of cryogenic liquid is coupled to the storage tank or piping system, and is in communication with the means for controlling flow.
