  • Argon recondensing method
    Patent number: 10006587
    Abstract: A method for condensing argon can include two flow streams interacting with each other in a heat exchanger found within a cold box: a stream of gaseous argon enters the heat exchanger to be cooled down below its liquefaction point by a stream of pressurized liquid nitrogen entering the heat exchanger. While passing through the heat exchanger, gaseous argon is gradually cooled down until it is condensed into liquid, flowing by gravity to the nearby liquid argon storage tank.
    Type: Grant
    Filed: October 6, 2015
    Date of Patent: June 26, 2018

  • Argon recondensing apparatus
    Patent number: 10006588
    Abstract: An apparatus for condensing argon can include cold box, which is preferably sealed and largely maintenance free, where all instruments and valves requiring routine maintenance are to be located outside, a nitrogen separator disposed within the cold box, a heat exchanger disposed within the cold box, the heat exchanger is configured to condense a gaseous argon stream against a pressurized liquid nitrogen stream. The cold box is elevated as compared to an argon storage vessel, such that the condensed argon stream can flow to the argon storage vessel without the need for a pump.
