Novatek has developed a technology for large-tonnage LNG production

“Novatek” received a Russian patent for its own large-scale natural gas liquefaction technology, called the Arctic Mix. This was said in a statement.

The technology provides for the use of mixed refrigerants and was developed for the implementation of Novatek’s large-capacity projects based on gravity-type bases with a capacity of one process line of more than 6 million tons of LNG per year.

As the company explains, the use of mixed refrigerants expands the geography of the technology, increases the energy efficiency of the process and reduces the amount of equipment used.

Novatek points out that the use of key technological equipment from Russian manufacturers will increase the competitiveness of the company’s large-tonnage LNG projects being implemented. “The development is an important step in the localization of liquefaction lines and is in line with the company’s strategic goal of developing LNG technologies in Russia,” the statement said.

Novatek previously had its own liquefaction technology, the Arctic Cascade. A patent for it was obtained back in 2018. It was implemented on the fourth line of the Yamal LNG project, with a capacity of 950,000 tons per year.

In April 2023, the company received a Russian patent for the Modified Arctic Cascade liquefaction technology. At that time, the company reported that this technology was planned to be applied to the company’s large-tonnage LNG projects in the Arctic region with a capacity of one production line of 3 million tons per year.

Now “Novatek”, in addition to the current Yamal LNG project, is implementing the Arctic LNG – 2 project with a design capacity of 19.8 million tons per year. The first line of the plant should be launched in December 2023, the second line is expected to be launched in 2024, the third – in 2026.

At various times, the company announced plans to build the Ob LNG, Arctic LNG-1, Arctic LNG-3 plants and an LNG plant in the Murmansk region.
