​Our Plant

ADGAS operational core is the gas liquefaction plant on Das Island, which consists of three trains that process an average of 8 million tons of associated and non-associated gases per year.

Trains 1 and 2 were originally commissioned in 1977, each with an operating capacity of 180 tons of LNG per hour. In 1990, ADGAS and its largest customer, the Tokyo Electric Power Company (TEPCO)  "JERA Co., Inc. is a recently formed joint venture between two of Japan's largest power utility companies --Chubu Electric Power Co. Inc. and Tokyo Electric Power Company (TEPCO)", signed a long-term agreement to expand and consolidate their operations, which prompted ADGAS to build what was then the world’s largest and most advanced LNG train in 1994.

The new train enabled ADGAS to double its production and output levels. Since then, all three trains have consistently operated at a higher capacity than their original designs as a result of frequent upgrades and debottlenecking carried out by ADGAS experts.

The ADGAS gas liquefaction plant is unique in its ability to process both associated and non-associated gases produced during oil production. Trains 1 and 2 can handle both types of gases at high and/or low pressures, while train 3 exclusively handles high pressure gas. This versatility is vital because feed gas obtained from Abu Dhabi’s offshore oilfields comprises both associated and non-associated gases.
Associated gas is obtained from the Umm Shaif, Zakumand Bunduq oilfields, whilst natural gas is found at the Abu Al BukhooshKuff, Uweinat and Umm ShaifKhuff oilfields. In total, the plant receives 12 distinct gas streams, and blends them to produce LNG and LPG and Pentane to meet clients’ requirements.

The plant’s 3 trains’ capacity is around 8 million tons a year of LNG, LPG, natural gases, paraffinic naphtha and sulfur.

In addition to the three trains above, ADGAS has built another two trains within the Offshore Associated Gas (OAG) project, an ADNOC sole risk project that is part of the wider Integrated Gas Development (IGD) project, which aims to provide Abu Dhabi with its future needs of natural gas.
ADGAS commissioned the OAG (Off-Shore Associated Gas) and IGD (Integrated Gas Development) facilities in 2010 and 2013, respectively, enabling gas export from Offshore Das Island to onshore Habshan facilities in Abu Dhabi through a 30 inch gas subsea pipeline.
OAG,  was commissioned in 2010 with export capacity of 200mmscfd of gas which increased to I000 mmscfd with the commissioning of IGD in 2013.
Both, the OAG (two processing trains)and the IGD (three processing trains) facilities receive, compress and dehydrate gases, which is then exported to Habshan facilities for further processing to Sales gas quality, thus increasing the supply of gas for domestic use.
