Seeking help with the liquid nitrogen vaporization process
Thread Content
8-kilogram liquid nitrogen storage tank, air-bath vaporizer; required outlet nitrogen pressure is 10 kilograms? How does this process work? A control valve and a check valve are installed at the outlet of the liquid nitrogen tank, while a safety valve and pressure regulation mechanisms are placed at the outlet of the vaporizer. The pressure regulation mechanism is linked to the control valve at the outlet of the storage tank, so that the liquid nitrogen level can be adjusted based on the pressure at the nitrogen outlet of the vaporizer. This nitrogen outlet pressure is even higher than the pressure in the storage tank itself; liquid nitrogen can get through on the first attempt, but how can it get through afterwards?
A liquid nitrogen pump (one in use and one as backup) is added at the outlet of the liquid nitrogen tank to raise the pressure to above 10 kilograms, after which the gas enters an air-bath vaporizer. A safety valve and a pressure control valve are installed at the outlet of the vaporizer, with the pressure of the nitrogen pipeline being controlled through the pressure control valve
