Angola LNG is a
liquid natural gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled down to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the vol ...

Technical features
The Angola LNG plant is a single train facility with production capacity of 5.2 million tonnes per year. The plant uses
ConocoPhillips' proprietary natural gas liquefaction technology (Optimized CascadeSM Process).
[
] In addition to LNG, it also produces
propane,
butane and condensate.
The plant is supplied from offshore gas fields on blocks 14, 15, 17 and 18, and from non-associated gas fields Quiluma, Atum, Polvo and Enguia.

The LNG project is presented as environmentally friendly by its designers, because most of its feedstock will consist of associated gas produced in association with crude oil in offshore field, that is currently
flared. However, while LNG production is more environmentally friendly than flaring, liquefaction is also a highly energy-intensive process and a significant percentage of the gas must be burned to generate the energy to cool the rest.
The plant was constructed by
Bechtel.
[ The LNG plant cost US$9 billion, and it was commissioned in 2013.][
] The first LNG was shipped on 16 June 2013.[

merged with Total.
Angola LNG was formed as a joint project in 2008 involving Cabinda Gulf Oil Company, a subsidiary of Chevron Corporation (36.4%), Sonangol (22.8%), BP (13.6%), Eni (13.6%) and Total (13.6%).[
] Sonangol and Chevron serve as co-project leaders. The shareholders will provide associated gas from their respective offshore oil fields. Director of Angola LNG is Eric Dunning.[

Challenges
Angola LNG faced an extended plant shutdown of more than three years from December 2015 to January 2019 to sort out a number of project issues that caused an incident on 10 April 2015.
