WebFeb 21, 2024 · One of the problems recognised early on with the storage of gases as liquids at cryogenic temperatures (typical -150 o C) is boil-off gas (BOG). This occurs when heat from a variety of sources transfers into the tank causing the liquid to boil and the pressure in the tank to rise. What causes boil-off? WebIn cryogenic storage applications, boil-off rate (the rate that a liquid gas is lost via evaporation) is a primary consideration. 3M glass bubbles can help reduce the boil-off rate considerably, including up to 44% reduction for hydrogen in large storage volume, concentric storage spheres.
