MOSCOW (MRC) -- Hyosung Chemical Corporation, one of South Korea's largest industrial conglomerates, has shut production at its No. 1 propane dehydrogenation (PDH) units at Ulsan, South Korea complex, after a fire broke out here, which took responders up to ten hours to extinguish, according to CommoPlast with reference to local media reports.
This PDH unit's production capacity is 200,000 mt/year of propylene. It was shut on 4-5 September.
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 PDH units with total outputs of 500,000 tons of propylene/year.
As MRC informed earlier, in February 2021, Linde announced that it has partnered with Hyosung Corporation (Hyosung), to build, own and operate extensive new liquid hydrogen infrastructure in South Korea.
According to MRC's ScanPlast report, PP shipments to the Russian market were 727,160 tonnes in the first six months of 2021, up by 31% year on year. Supply of homopolymer PP and block-copolymers of propylene (PP block copolymers) increased. Supply of statistical copolymers of propylene (PP random copolymers) subsided.
