Oct 19, 2015 · Lower LNG tank pressure, longer holding time As heat leaks into the tank, LNG evaporates and slowly increases the tank pressure. The classification society requirement for a minimum holding time of 15 days regulates the minimum insulation requirements for an LNG storage tank.

LNG Storage Tanks LNG is generally stored in large-volume above-ground low-pressure (less than 5 pounds per square inch gauge) tanks. The tank is double-walled, with a carbon steel outer wall and a nickel-steel inner tank. Nickel steel inner tanks are used because ordinary steel is too brittle to use in direct contact with the cryogenic LNG.
Low-Pressure Storage Tanks - an overview ScienceDirect Low pressure tanks are designed to withstand internal pressure in the range 0.515 psig. The design of low pressure tanks is governed by API Std 620. Low pressure tanks are suitable for the storage of liquids which are too volatile for atmospheric storage. Gasoline is a
