The arrival in Hungary of Russian crude that is up to standard has resumed through the Druzhba pipeline, Hungarian oil and gas company MOL said late on Thursday. Russian pipeline operator Transneft said a day earlier that clean oil would arrive in Hungary by Wednesday evening. A number of refineries in Europe suspended oil imports via the Druzhba pipeline on April 19, after it was found to contain high levels of organic chloride, a material used to boost oil output which must be separated before shipment as it can damage refining equipment. Hungary’s government earlier sanctioned the partial release of national strategic oil reserves to supply MOL’s refinery in Százhalombatta, south of Budapest, for a period up to two months.
