During the month of May, LPG will make up 10% of the total mixed feed with naphtha, the source said.
The use of mixed feed at the Yeosu plant comes after the company started using mixed feed at its Daesan-based aromatics plant.
The Daesan-based aromatics unit that has a nameplate capacity 260,000 tonnes/year of benzene, 54,000 tonnes/year of toluene and 36,000 tonnes/year of solvent xylene, has been fed with 10% LPG since second-half of March and into April as well, he said.
The overall aromatics output remained unchanged despite the use of lighter feedstock, as the company purchases more pygas for aromatics extraction to cover the production shortfall.
Both the Daesan and Yeosu aromatics facilities are operating at full capacity, the source said.
