FERC initiates pre-filing review for Pointe LNG project

Hydrocarbon Engineering,

FERC has issued a letter initiating its pre-filing environmental review process for the proposed Pointe LNG liquefaction and export terminal on the east bank of the Mississippi River in Plaquemines Parish, Louisiana, US, and the interconnected pipelines.

The proposed liquefaction project will consist of three LNG liquefaction trains, each with a nominal capacity of 2.0 million tpy. The total project capacity is approximately 6.0 million tpy.

Each liquefaction train will contain one heavy hydrocarbon removal module, one liquefaction module, and two parallel refrigerant compressor strings. Each refrigerant compressor string will consist of a mixed refrigerant compressor and propane refrigerant compressor driven with a single gas turbine in a tandem common shaft arrangement. There will also be a single common condensate stabilisation system processing the natural gas liquids from all three trains.

Two LNG storage tanks, each with a net capacity of 160 000 m3, will be of a full containment design, with a 9% nickel steel inner tank, post tensioned concrete outer tank, freestanding carbon steel liner, and aluminium suspended insulation support deck. The LNG will be contained within the inner tank, while the outer tank will contain product vapours. The concrete outer tank will also provide secondary containment in the event of leakage of liquid from the inner tank. The inner and outer tanks will be supported on a common foundation. The tank will be designed and constructed in accordance with the requirements of American Petroleum Institute (API) Standard 620 including Appendix Q, API standard 625, American Concrete Institute 376, National Fire Protection Association (NFPA) 59A and 49 CFR Part 193.
