Vietnam's Dung Quat Refinery restarted Friday, following a shutdown for maintenance that ended earlier than expected.
State-owned oil and gas group PetroVietnam stopped the 130,000-barrel-a-day refinery on July 15 for scheduled maintenance, which was scheduled to last through mid-September.
The plant is expected to be operating at full capacity within ten days, news website VnExpress reported, citing Nguyen Hoai Giang, Chief Executive of Binh Son Refining and Petrochemical Co, which operates Dung Quat.
Giang said all technical problems have been solved during the shutdown, while crude storage capacity was increased by 34 percent.
He said the next maintenance is due in four years, when local technicians and experts are set to be capable of fixing problems themselves without depending on foreign expertise.
Dung Quat produced more than 3.3 million tons of oil products in the first seven months, nearly 60 percent of the target for 2010.
Vietnam plans to expand the annual capacity of the plant to ten million tons by 2017, from 6.5 million tons.
