Three people were injured when the Abadan Refinery in Iran exploded due to excessive heat on Saturday, Iranian media reported.
The oil refinery, located in the city of Abadan south of Ahwaz, is the largest, oldest, and most important Iranian oil refinery.
Iranian authorities said the accident was caused by increasingly high temperatures around the presence of flammable materials, which resulted in a technical malfunction followed by an explosion.
The explosion occurred in the refinery’s third unit and caused a massive fire in the section,
according to Iranian media.
There were also reports of a huge cloud of smoke and air pollution in the city of Abadan.
The Abadan Refinery has experienced several accidents in recent years due to what Iranian authorities say is a “lack of safety measures.”
The refinery processes 400,000 barrels of heavy crude oil daily and turns it into petroleum products and derivatives.
Until 1980, it was the largest oil refinery in the world.
