(Arabian Oil and Gas) -- Iranian Fars News Agency reported that an explosion hit the Abadan Refinery, located near the coast of the Arabian Gulf. The news agency said that the explosion was due to a technical problem. Subsequent reports state the explosion was the result of a gas leak.
According to the Fars agency, Iranian president Mahmoud Ahmadinejad - who was visiting the refinery at the time - was not hurt. However, the explosion caused one death and left 22 wounded.
The refinery was completed in 1912 and was one of world's largest oil refineries when it was destroyed in 1980 by Iraq in the Iran-Iraq war.
The refinery had a capacity of 635.000 b/d in 1980 and formed a refinery complex with important petrochemical plants. Its capacity has been increased steadily since the war ended in 1988. Its capacity is now listed as 400.000 bbl/d crude oil.
