Apparatus for detecting leakage of LNG tank and Method for detecting leakage of LNG tank

摘要

LNG tank leak detection system and the LNG tank leak test method is disclosed. LNG (Liquefied Natural Gas) the first vessel (vessel) and for receiving, as a device to check the leakage of the LNG tank consisting of a second vessel such that a first space is formed covering the first vessel, the inner wall of the first vessel and trace gas injector for injecting a tracer gas (tracer gas) adjacent the examination region, the first trace gas detector which is connected to the vacuum pump and a vacuum pump which sucks the gas in the first place detect the trace gas from the inhaled gas the LNG tank leak detection device comprises, can detect the leak position to advance to minimize the cost of installation and dismantling scaffolding installed by performing the leak test and precise scaffolding parts only.
