Elba Liquefaction Co. LLC and Southern LNG Co. LLC, which had applied in March 2014 at the Federal Energy Regulatory Commission for approval of a liquefied natural gas (LNG) project in Georgia, on July 8 filed with FERC a Title V air permit for the project that was issued in June by the Georgia Department of Natural Resources.
The companies plan to add natural gas liquefaction and exporting capabilities to Southern LNG’s existing Elba Island liquefied natural gas terminal in Chatham County, Georgia (called the “Elba Liquefaction Project”).
Southern LNG submitted a permit application with the state in May 2014 for the construction and operation of a natural gas liquefaction and exporting terminal named Elba Liquefaction Terminal. The facility will include the following equipment:
- Six Moveable Modular Liquefaction System (MMLS) units that will treat feed natural gas and cool it until it is liquefied. The six MMLS units will have a combined nominal output capacity of 1.5 million tonnes per annum (MTPA).
- Two heaters that will provide heating for medium used for heating in the natural gas liquefaction process. Each of the heaters has a design input capacity of 98.1 million Btu per hour (MMBtu/hr) and will fire exclusively boil-off gas and natural gas.
- Two diesel emergency generators that will provide backup power to the facility. Each generator engine has a design output capacity of 3,353 horsepower (Hp), which is equivalent to 2.5 MW.
- Two thermal oxidizers that will treat the acid gas stripped from the feed gas. Each thermal oxidizer has a design input capacity of 32.8 MMBtu/hr and will fire exclusively boil-off gas and natural gas.
- A process flare system that has a multi-point ground flare design with a 60-feet high fence. The purpose of this flare is for safe routing of combustible hydrocarbons for startup and shutdown of the liquefaction process, during upset conditions, and for vent streams.
- An elevated marine flare that is for safe routing of recovered vapors from liquefied natural gas carriers at the south dock that do not contain LNG or natural gas (i.e., inerted carriers) on arrival.
- One fire water pump that will be used in the event of a fire. The pump engine has a design output of 493 Hp and will fire exclusively on distillate fuel oil.
- Two storage tanks for storing recovered amine and heating medium.
- Four MMLS units that will have a combined nominal output capacity of 1.0 MTPA.
Under this air permit, the companies need to commence construction of one or all of the emission units included in the permit within 18 months of the date of issuance of this permit, or the permit will lapse.
