After updates at 2012 Ufaneftekhim DCU becomes up to 1.6 mtpy. Main update is the new preheat furnace that allowed to reduce duty of reaction furnaces and allow to increase capacity.
p.s. Ufaneftekhim is not doing anode coke because there are too much sulphur contains at the feed.
p.p.s sorry for my english. i have not pactice for a lot of time.
