Rapid phase transition
Rapid phase transition or RPT is an explosive boiling phenomenon realized in liquefied natural gas (LNG) incidents, in which LNG vaporizes violently upon coming in contact with water causing what is known as a physical explosion. During such explosions there is no combustion but rather a huge amount of energy is transferred in the form of heat from the room-temperature water to the LNG at a temperature difference of about 200 °C (350 °F).
