LNG (liquefied natural gas)
Pressure relief valves, cryogenic safety valves and deflagration / detonation flame arresters
CASH, BAILEY, BIRKETT, MARVAC and MARSTON protect LNG storage tanks from atmospheric pressures and over pressurisation. AMAL prevents the propagation of flames to protect pipelines and storage tanks from fire and explosion.
Cryogenic pressure relief
Liquefied natural gas (LNG) is typically stored at very low temperatures in insulated atmospheric pressure storage tanks and turned back to a gas on site, whenever demand is generated. The extreme temperature difference between its cryogenic storage temperature and the changing ambient temperature means that internal pressure needs to be released on a regular basis in order to protect the tank from damage.
Cryogenic relief valves, safety valves and bursting discs from CASH, BAILEY, BIRKETT and MARSTON protect LNG storage tanks from the effects of temperature changes and subsequent over pressurisation, while MARVAC low pressure relief valves and tank blanketing valves allow the tank to breathe, preventing damage and spillage. AMAL Flame arresters can be installed on the tank roof to prevent the propagation of fire into the system
