South Korea’s Hyosung shut Ulsan plant after fire

According to local media reports, Hyosung Chemical Corporation has stopped production at the Ulsan, South Korea complex after a fire broke out here, which took responders up to ten hours to extinguish. No casualties were reported. 

According to a statement from the Ulsan Ministry of Defense, the fire first broke out from Hyosung Chemical Yongyeon Plant 1 at 8:43 PM on 4 September 2021. Initial investigation showed the cause of the fire was a gas leak at the propylene plant. 

The authorities ordered the company to stop all manufacturing processes and discharge residual gas for safety precaution. Damage assessment is taking place and it is unsure how long the plant would remain offline. 

At the Ulsan complex, Hyosung owns three PP lines with a combined capacity of 550,000 tons/year and two propane dehydrogenation units with total outputs of 500,000 tons of propylene/year.
