A German chemical company will see its gas treatment technology deployed in Russia’s promising USD 27bn Yamal LNG) project set to generate as much as 16.5 million tonnes per annum of the super-chilled gas in the coming years.

Joint venture company Yamal LNG has announced that it will deploy BASF’s Oase technology for the extraction of carbon dioxide from the liquefied natural gas (LNG) to be refined at its LNG plant in the Yamal peninsula, eastern Siberia. Yamal LNG is owned by Russia’s largest independent gas producer and second largest gas producer, Novatek (80 per cent share) and French energy firm Total (20 per cent share).

Carbon dioxide is typically extracted at a liquefied natural gas (LNG) plant upstream of the liquefaction process. Along with other components such as benzene and water, it must be removed in order to prevent it from freezing at low temperatures required for LNG storage or so as not to cause damage to the liquefaction facility.

"The application of this technology in an Arctic LNG project is well justified," Total LNG expert Christof Thoma said.

Novatek deputy chairman AM Fridman added: "The agreement with BASF is signed full conformity with the project implementation schedule and is another important step towards the final investment decision on the Yamal LNG project," said.

After its development period scheduled from 2012 to 2018, Yamal LNG is expected to yield around 16.5 million tonnes per year of LNG for the next 21 years, experts say. This production will be based on three LNG trains with a capacity of 5.5 million tonnes per year of LNG each. In total, this amounts to half of South Korea’s annual gas needs. LNG shipments are expected to commence in 2016.
