Questions regarding LNG cryogenic tanks
Thread Content
Dear experts, I have a question as a beginner: why is there a large pressure difference between the location behind the gas-phase throttle valve in the LNG cryogenic tank and the location before the refrigerant exits the tank and reaches the compressor?
The compressor compresses gas, which then becomes liquid after being condensed in the condenser, and afterwards there is throttling. Xiaobai can do it; he needs to make full use of the resources available around him. There are technical staff at the workplace, and it is their responsibility to teach you the necessary skills. For reference.
Is this pressure difference the same from when the machine is started up until it reaches normal operation? If we check the design documents, there should not be such a large pressure difference; if there is, then channel blockage needs to be considered ； If there are no issues at the start of driving, it’s possible that undercooling could lead to liquid accumulation
