A fire at a storage tank at the Gaoqiao oil refinery in Shanghai's industrial Pudong district has been extinguished after an explosion on Sunday morning sent black smoke billowing into the sky.
The fire was at a naphtha storage tank, with a capacity of about 1,000 tonnes, a Sinopec media officer told Reuters, adding that there would be no impact on production.
The explosion occured around 11.23am and extinguished around 2.30pm, according to the Gaoqiao district firefighting department, which mobilised trucks to contain the blaze and prevent it from spreading.
No-one was hurt, said an official at the department.
The 2,30,000 barrel-per-day refinery is one of China's largest. It is owned by Sinopec, China's largest oil refining corporation.
