WitrynaLNG is usually stored at atmospheric pressure and at its atmospheric pressure boiling temperature of approxima-tely –1628C. If there is any spill or loss of containment, flammable vapor (predominately methane) will be produced due to the heat transfer to the liquid pool. The initially cold vapor resulting from vaporization will be denser ...
