Australian engineering firm Worley has secured a contract from QatarEnergy LNG, previously known as Qatargas, to provide front-end engineering design (FEED) services for the latter’s CO2 sequestration project in Ras Laffan, Qatar.
Worley said in a statement on Monday that its teams in Qatar and Australia will develop the FEED study and engineering, procurement and construction (EPC) scope of work.
The Australian firm said it will complete the project next year, but it did not provide the price tag of the contract.
Once completed, the sequestration facility will be capable of capturing 4.3 million tonnes of CO2 every year, helping to further reduce QatarEnergy LNG’s environmental impact across the LNG value chain by reducing emissions from its seven LNG trains at QG North and three LNG trains at QG South.
Worley said the facility will capture CO2 from the trains, compress it, and inject it into the new injection wells.
New compression trains and pipelines need to be installed after FEED is completed.
Drawing in on expertise from its CCUS centers of excellence, the project team will aim to prove the pre-FEED concept by modelling the CO2 capture process, Worley said.
This high-level technical approach aims to further instill confidence to expand the CO2 sequestration technology in the future to include the remaining trains at Qatargas South and North, it said.
Huge LNG expansion
LNG producer Qatargas, a unit of QatarEnergy, recently changed its name to QatarEnergy LNG.
Established in 1984, Qatargas currently operates 14 LNG production trains with a capacity of about 77 Mtpa in Ras Laffan.
However, state-owned QatarEnergy is significantly increasing LNG production from the North Field.
This first phase of the expansion project will increase Qatar’s LNG production capacity from 77 to 110 Mtpa, while the second phase will further boost capacity to total 126 Mtpa.
QatarEnergy, previously known as Qatar Petroleum, changed its name in October 2021 to reflect its role as an active global partner in the energy transition.
