UPDATE 1-Explosion at MOL's Tiszaujvaros petrochemical plant kills one, injures several

An ​explosion at Hungarian oil and gas ​group MOL's petrochemical plant ‌in Tiszaujvaros, eastern ​Hungary, has killed one person and seriously injured several others, the company said in a statement ‌on Friday.

Prime Minister Peter Magyar said in a Facebook post that his economy minister Istvan Kapitany and MOL's executive chairman Zsolt Hernadi were en route ‌to the plant. Magyar also posted a photo that showed huge black ‌smoke billowing out of the plant. "An explosion occurred at MOL Petrochemicals' site in Tiszaújváros during the restart of the Olefin 1 plant. The fire was localised by firefighters, ⁠and ​the intervention is ⁠still ongoing," MOL said.

"The circumstances of the accident are being investigated by experts," the company added, ⁠without giving further details. Kapitany, in a Facebook post, said that according to ​current information, a compressor exploded during the restart of the Olefin 1 ⁠plant and the fire was still being put out.

The Olefin 1 plant is a ⁠steam ​cracker unit at MOL's petrochemical plant in Tiszaujvaros. The production capacity of MOL's Olefin-1 plant is approximately 370,000 metric tons of ethylene per ⁠year. There are two steam crackers in Tiszaujvaros with 660 kt/y ethylene capacity ⁠according to ⁠MOL's own website. MOL uses the majority of its ethylene internally to manufacture polyethylene plastics, which are sold to the plastics ‌and ‌packaging industries.
