Russia has used railways, storage tanks and a ship to remove polluted oil from an export pipeline, has so far extracted about 2 million tons of polluted oil, or one-third of total polluted quantities, data showed.
A month ago, Russia was forced to stop exports via the Druzhba pipeline to Poland and Germany in the northern section of the line to Ukraine, Slovakia and the Czech Republic in the south.
Druzhba, world’s longest oil pipeline and one of the biggest oil pipeline networks in the world.
It carries oil some 4,000 kilometres (2,500 mi) from the eastern part of the European Russia to points in Ukraine, Belarus, Poland, Hungary, Slovakia, the Czech Republic and Germany
The pipeline runs at the Moser refinery in Belarus.
According to a Belorussian company operating a sector in Druzhba, about 5 million tonnes in total could be contaminated with organic chloride used to boost oil extraction.
The restoration of the flows fully requires up to six months.
The lion’s share of polluted oil, or up to 2 million tons, remains in pipeline systems in Russia, Russia and Ukraine.
Another nearly one million tonnes is confined to Poland and Germany, according to industry traders and sources.
Efforts within Russia and Belarus to extract polluted oil from the pipeline are vital because it cannot resume normal flows or export clean oil until Druzhba is emptied of polluted oil.
