Liquid nitrogen wash for effusion
Thread Content
What is the role of adding liquid nitrogen during the process of washing away fluid with liquid nitrogen? Can it enter the nitrogen washing tower and the hydrogen separation tank?
Under normal circumstances, it is not allowed to add more liquid nitrogen to cool the accumulated liquid in the system; liquid nitrogen is added only when the system needs to accelerate its processing speed or when the temperature of the gas delivery system rises rapidly due to the system not having reached a sufficient cooling level.
