Russian oil group Rosneft said Wednesday it expected production of ethylene at its Angarsk polymer plant, Russia, by the start of June.
The Angarsk plant stopped work because of a partial failure of equipment.
Rosneft did not say when that happened.
Sayanskkhimplast, which receives ethylene from the Angarsk cracker, said March 4 it was preparing to fully suspend production of ethylene derivative polyvinvyl chloride and upstream caustic soda owing to an interruption in ethylene supplies from Angarsk.
The Sayanskkhimplast plant has been running on a regime of austerity since February 10, reducing procurement of materials and equipment, Sayanskkhimplast said March 4.
The Angarsk polymer plant produced 135,000 mt of ethylene, 80,500 mt of propylene, 65,100 mt of high density polyethylene, 20,800 mt of styrene, 15,600 mt of polystyrene and 59,300 mt of benzene in 2014, according to company data.
Its ethylene and propylene output accounted for 5.64% and 6.48%, respectively, of Russian production of those products, according to Platts calculations based on data from Rosneft and Russian statistics agency Rosstat.
Sayanskkhimplast, one of Russia's largest PVC and caustic soda producers, accounts for around 45% of Russian PVC output and 17% of caustic soda output.
Total Russian PVC and caustic soda production were 847,174 mt and 1.1 million mt, respectively, in 2015, according to Rosstat data.
Ethylene accounts for about 43% of PVC feedstock costs. Chlorine accounts for about 57%.
