USING LNG CRYOGENIC VACUUM HEAT REJECTED VOLUME LEAKING HEAT DETECTED

Performance of LNG cryogenic vacuum heat rejected volume decreased,because of gas releasing or leaking of the volume wall material,or old and loose interlayer material. And cryogenic volume evaporation will increase, which result in volume set at dangerous state. Therefore it is necessary to detect cryogenic volume performance via simple method,in order to ensure safety of person and reduce the waste of LNG liquid. Detected equipment will alarm if the cryogenic volume evaporation exceeds the limit.
