LNG storage tank safety assessment methods

Content

Numerical Simulation and Key Performance Indicators (KPIs): Numerical simulation is used to study the effects of operating parameters and geometry on pressure build-up and complex phenomena (e.g. thermal stratification) in tanks, and to define a set of KPIs to support the safety assessment of LNG storage tanks.
Design and construction standards: LNG storage tanks need to fulfill certain design and construction standards to ensure their safety, stability and economy. These standards are divided into overall standards for LNG production, storage and transportation, and design and construction standards for the LNG tanks themselves.

Valve safety for cryogenic storage tanks

LNG storage tanks and pipes are made of austenitic stainless steel. Austenitic stainless steels have excellent low temperature properties. But the linear expansion coefficient is high. under the temperature conditions of liquefied natural gas The shortening rate of stainless steel is about 3/1000, and for the 304L material pipeline, when the working temperature is -162 degrees, the 100 m pipeline can be shortened about 300 mm.
