  • Gas delivery at high flow rates
    Patent number: 6581412
    Abstract: This invention is directed to a method for delivering a liquefied compressed gas with a high rate of flow comprising passing a liquefied compressed high-purity semiconductor gas into a storage vessel; positioning a temperature measuring means onto the wall of the compressed gas storage vessel; positioning at least one heating means proximate to the storage vessel; monitoring the resulting temperature with the temperature measuring means; positioning a pressure measuring means at the outlet of the storage vessel and monitoring the vessel pressure; adjusting the heat output of the heating means to heat the liquefied compressed gas in the storage vessel to control the evaporation of the liquefied compressed gas in the storage vessel; and controlling the flow of the gas from the storage vessel.
