Arzew/Bethioua LNG terminal consists of 13 natural gas liquefaction trains, with a total capacity of 20.8 million metric tons per year (mtpa), or 2.98 billion cubic feet per day (bcfd). It is owned by Sonatrach, an Algerian state-owned hydrocarbon resources company.

Arzew GL4-Z

The Arzew GL4-Z facility had three 0.5-mtpa liquefaction trains, for a total of 1.5 mtpa. It was built in 1964.[1]

It was shut down in 2010, after the completion of GL3-Z.[2]

Bethioua GL1-Z & GL2-Z

The existing Bethioua GL1-Z and GL2-Z each have six 0.75-mtpa liquefaction trains, for a total of 12; the total nominal capacity is 16.1 mtpa. GL1-Z was built in 1978, and GL2-Z in 1981.[1][3] When built, the Bethioua plant was the largest LNG export facility in the world.

GL1-Z was repaired and renovated in 1991-97, helping relieve problems that had caused its capacity to be consistently under capacity.[4]

According to the International Group of Liquefied Natural Gas Importers' 2020 Annual Report, GL1-Z had a total nominal capacity of 7.9 mtpa and GL2-Z had a total nominal capacity of 8.2 mtpa.[5]

Arzew GL3-Z expansion

Arzew GL3-Z is a new single liquefaction train, with 4.7 mtpa capacity.[6][7]

The project was started in 2008, and was completed in November 2014. It cost €2.8 billion, or about $3.8 billion. The engineering, procurement, and construction (EPC) contract was carried out by a joint venture of Italian firm Saipem and Japan's Chiyoda Corporation.[8][9]
