Questions and Answers
The IGU LNG Storage and Vaporization Facilities store and vaporize ______ for delivery into the natural gas distribution mains in Fairbanks.
liquefied natural gas (LNG)
The LNG storage tank at Site 3 is a cryogenic vessel designed to store LNG at -320oF at a maximum gauge operating pressure of 2.75 psi, but IGU stores LNG in this tank at about -230OF at 0.25 – 2.0 psi gauge. The LNG storage system is the storage tank T-500, a 5.25 MMUSG (430 MMSCF) double-walled full containment LNG storage tank with a prestressed concrete outer tank and a 9% nickel steel inner LNG tank. The LNG tank foundation is designed to maintain a temperature of between 15 and 25 degrees Fahrenheit at the base of the material foundation supporting the LNG tank. The facilities use an active horizontal refrigeration system to keep the existing sub-grade around the tank in a constant state of frozen ground. The ______ system used at the LNG Storage Facilities utilizes a system of heat exchangers and gas-fired boilers looped together by a glycol system.
vaporization
The LNG Transfer System consists of an impounded area in which the LNG transport is parked in preparation for the offload of the LNG from the transport to the Storage Tank. Three boil-off compressors (BOCs) are installed to reduce the tank pressure by pulling and compressing the boil-off gas and directing it to exit the tank. The LNG Storage Site is supplied power through a 480 Volt 3 Phase service from the GVEA grid. A backup power supply is installed, consisting of a UPS and a generator. The IGU storage facility is equipped with adequate firefighting equipment, fire and gas detection systems, and an emergency shutdown device (ESD). ______ includes a chain-link fence and cameras.
