France-headquartered oil and gas industry process technologies provider Axens has announced winning a parcel of work on a project undertaken by Qatargas to build carbon dioxide sequestration facilities at its Ras Laffan export terminal in Qatar.

Axens said it had been awarded a subcontract by Medgulf Construction Company, the main contractor appointed by Qatargas by the Ras Laffan project, to provide a new triethylene glycol (TEG) dehydration unit for integration into the CO₂ sequestration units.

With water contained in the CO₂-rich stream, amounting to a volume of 98 per cent, a gas dehydration technology is required to avoid the risk of pipeline corrosion.

“Axens’ solution was selected and is based on TEG technology, which absorbs the water contained in the CO₂-rich stream counter-currently by lean TEG in a gas/glycol contactor,” Axens said.

The TEG unit will include three high-pressure contactors, three high-pressure separators and one common TEG regeneration delivered in modules.
