Why do we need the bottom of the tank heating system ?

As the storage temperature is very low, in order to prevent the tank base ( bottom ) occurs heaving and cracking , with tropical tanks will be installed in the pipe base to maintain the base temperature.
Product Storage Temperature Example:
LNG liquefied natural gas .......................................... -162 degC
LPG LPG .......................................... -145 degC
Liquid Nitrogen liquefied nitrogen .................... -196 degC
Argon Argon ............................................... ... -186 degC
Ammonia (NH3) Ammonia ................................. -36 degC
Liquid Oxygen liquefied oxygen ....................... -193 degC
Liquid Hydrogen Liquefied hydrogen .................. -253 degC

What heaving mean ?

Volume growth due to the icy frost heave is the role of moisture in the soil formed . Starting from the edge of the soil freezes , the ice would have been extended ( with surface vertical ) along the direction of heat loss .
One or multiple ice is enough power to lift the soil up to 30 cm or more.
Heaving pavement cracks and damage can lead to building foundations , such as the tank base plate .

Once the leak , what will happen ?

1944 Cleveland LNG disaster
LNG storage tank failure resulting gas leaking into nearby streets and sewers and burst into flames , the fire engulfed the nearby residential and commercial establishments .




2004 Algerian liquefied natural gas disasters.
Los Angeles Times - "Liquefied natural gas leak caused the explosion," the Algerian natural gas explosion caused at the center of 27 people were killed, the fuse is leakage of liquefied natural gas. Before the U.S. ambassador to Algeria, said fear in California and across the country are hungry supporters LNG import terminal.
