摘要
Abstract
This paper elaborates on the diagnosis and maintenance process for an internal leakage fault in a 2,500 m3 cluster tank during operation at an LNG stor-age and distribution station.Based on fault characteris-tics including abnormally rising interlayer pressure,a significantly elevated methane volume fraction,and a sharp increase in nitrogen consumption,the internal leakage of the storage tank is confirmed.The core maintenance procedures are described,such as perlite removal and stacking,precise detection and repair of leakage points,perlite backfilling,system pre-cooling,and commissioning.The successful resolution of the internal leakage fault of the cluster tank at the LNG storage and distribution station verifies the effective-ness of the stepwise diagnosis and leakage detection and maintenance scheme.关键词
