An explosion at South Korean petrochemical company Yeochun NCC's (YNCC) plant in the city of Yeosu has killed four people and injured four, a Yeosu Fire Station official said on Friday.
YNCC could not be immediately reached for comment.
YNCC's third naphtha cracker in Yeosu, which the fire station official said was the site of the explosion, produces 470,000 tonnes per year of ethylene.
YNCC's first and second naphtha crackers in Yeosu produce 900,000 and about 920,000 tonnes per year of ethylene each.
YNCC's entire capacity is 2.29 million tonnes per year, about 1.1 per cent of global capacity, Samsung Securities analyst Cho Hyun-ryul said.
