Algeria's GL4Z (Camel) plant at Arzew began operations in 1964 and was the world's first commercial scale LNG facility. The GL4Z plant was constructed by Technip and Pritchard and had the capacity to process around 160 mmcfd of feedgas. The three trains were identical liquefaction units. The plant was closed and decommissioned in late 2010. The LNG plant analysis outlines the key project metrics development and cost estimates of the plant gas feedstock fiscal structure and economic assumptions used to generate the project cashflow.
