According to market sources, S-Oil Corporation has brought the residual fluidization catalytic cracking plant (RFCC) online on 24 May 2022, four days after an explosion rocked the company’s refinery unit in Ulsan, forcing the maker to take all downstream plants offline as a safety measure.
The RFCC plant has an annual output of 200,000 tons of propylene.
CommoPlast is unable to rectify the operating status at other downstream plants at the time of this report. These units include:

In the meantime, S-Oil decided to carry out unscheduled maintenance work at the 1.79 million tons/year PX plant following the incident. The restart date is set for 15 July 2022.
