Control method and control unit of non condensate gas in condensed gas, discrimination method and discrimination unit

摘要

Problem to be solved: to control non condensable gas in condensed gas and to determine the presence or absence of non condensable gas in real time.In the method of controlling the non condensable gas in condensed gases, the interior of the container 2 containing condensed gas and non condensate gas is partially cooled to generate a condensing part 4 condensing the condensed gas, utilizing the flow of the non condensate gas resulting from the pressure drop of the condensation part By controlling the temperature of the condenser 4, the distribution of the non condensable gas in the condensed gas is controlled.AndA method of determining an uncondensed gas controlled by this control method isThe plasma generator 6 generates plasma inside the containerAt leastBy observing the emission spectrum of the plasma of each kind of non condensed gasOrBy comparing the temperature measured by the temperature sensor arranged in the condensing unit 4 with the temperature other than the condensation part 4 inside the containerThe presence or absence of uncondensed gas in condensed gas is determined in real time.Diagram
