Abstract

Nowadays, the expanded perlite as the cryogenic insulation material is widely used in LNG storage tank. And the settlement of expanded perlite will affect the safe operation of the cryogenic system. On the basis of the large cryogenic LNG storage tank, a settlement monitoring method based on distributed fiber optic of insulation materials is put forward in the paper. The locations of distributed fiber optic are determined and the threshold of monitoring system is investigated. Besides, other factors impacting the temperature of insulation layer are also discussed. Finally, it is confirmed that the monitoring program is effective by numerical simulation and theoretical calculation.
