LG Chemical has embarked on a review of its benzene derivative assets in South Korea.
The South Korean petrochemical giant expects a 10pc cut in benzene requirement in 2022. It has notified its local suppliers of a 50pc reduction in 2022 term benzene needs.
The target and timeline of the review remain unclear. The company plans to resume its benzene derivative operations in Daesan as soon as it completes maintenance on its upstream naphtha cracker.
LG Chemical recently extended the planned turnaround of its Daesan naphtha cracker by 12-13 days. The 45-day scheduled turnaround was initially targeted for completion on 14 November.
LG Chemical owns two crackers in Daesan and Yeosu capable of producing 271,000 t/yr and 390,000 t/yr of benzene, respectively. The company operates SM units of 170,000 t/yr and 500,000 in Daesan and Yeosu respectively. It also runs two 400,000 t/yr cumene plants in Daesan and Yeosu.
LG Chemical's Daesan cracker is capable of producing 1.27mn t/yr of ethylene and 650,000 t/yr of propylene. It is expected to resume operations at the end of November.
Cumene is a pre-cursor to phenol. Argus data showed average phenol margins of $125/t so far in 2021, compared to $301/t in 2020 and $66/t in 2019. SM production margins averaged $249/t in 2021, compared to $195/t in 2020.
SM production margins were estimated at $286/t in early November, 11pc lower from $320/t in early June.
South Korea is the world's largest benzene exporter. Customs data showed the country exported more than 2 mn t/yr of benzene in 2020.
