MOSCOW, May 3 (Reuters) - Russian energy company Novatek plans to start test operations for a new processing unit at its gas condensate complex at the Baltic Sea port of Ust-Luga in mid-June, three market sources told Reuters.

The complex processes gas condensate at two units into light and heavy naphtha, jet fuel, fuel oil and gasoil, enabling the company to ship oil products as well as gas condensate to international markets.

In 2023 the Ust-Luga complex processed 7 million metric tons of gas condensate, Novatek data shows.

The new refining unit, with capacity of 3 million metric tons a year will allow the company to increase naphtha exports to between 550,000 and 600,000 tons a month from 350,000 to 370,000 tons currently, Reuters calculations show.

Novatek, which exports naphtha mostly to Asia, including China, Singapore, Taiwan and Malaysia, did not respond immediately to a request for comment.
