Apr 04, 2023

An LNG storage project with the world's first on-land GST membrane full containment LNG storage tank located in Hejian in China's Hebei province has been officially commissioned, People's Daily Online reported on February 24.

The project had been running for more than 100 days since it began trial operations in October last year. During the trial period, the facility gasified over 1mn ft3/day of LNG, supplying gas to 800,000 urban households in Hejian city, the state-owned People's Daily reported.

The tank requires 90% less steel and produces 27% less carbon emissions compared with an LNG storage tank using traditional technologies. The GST technology is a new generation of LNG membrane-type land storage tank developed by France's GTT.

The GST membrane full containment system of the project includes a nitrogen system, an online gas detection system, and thermal corner protection system, which help significantly reduce the evaporation of the LNG stored in the tank, thus ensuring the safe operation and integrity management of the facility.

The project is funded by Huagang Gas Group Co., a natural gas supplier in Hebei province, and the core membrane full containment tank was built by Hudong-Zhonghua Shipbuilding (Group) Co., a subsidiary of China State Shipbuilding Corporation, People's Daily said.
