Background:
    It is estimated that by 2020 gas will supply about 25% of the global energy demand and with the benefit of being a relatively clean fuel this percentage will further increase. As many of the world gas reserves are geographically isolated from the market LNG will play a major role in the efficient delivery of gas to the
end user.

Application:
   The production of LNG by conversion of natural gas to liquid is done in a series of processes that are commonly known as “gas trains”. During these processes the gas is cleaned and dried, liquefied by cooling to -160° C and stored in large LNG storage tanks ready for pumping to LNG Tankers.
Foundation Heating for Refrigerated Storage Tanks
   LNG is stored in large insulated atmospheric storage tanks. As the LNG is stored at -160° C the foundation slab requires heating to prevent frostheave and potential foundation buckling due to an ice lens formation, resulting in potential destruction of the tank. Other typical cryogenic products that also require slab heating are Butane and Propane.
