Some refining facilities at HD Hyundai Oilbank's Daesan plant in Seosan, South Chungcheong Province, temporarily halted operations due to instrument issues before resuming procedures approximately two hours later.
According to industry sources on October 20, the crude distillation unit (CDU) and delayed coking unit (DCU) at the Daesan plant experienced a shutdown. The CDU is a critical facility that heats crude oil to separate it into products such as naphtha, kerosene, and diesel. The DCU breaks down residual oil generated during the refining process to produce lighter oil fractions.
The shutdown was initially suspected to be related to power supply issues; however, it was later confirmed to be an instrument-related problem. The affected facilities are currently undergoing restart procedures, and the impact on production is expected to be limited.
An HD Hyundai Oilbank official stated, "There was an impact on the process operations due to instrument malfunctions in some facilities at Daesan Plant 1, but immediate measures were taken. The processes that experienced issues are currently in the restart phase, and we anticipate that there will be minimal impact on production and product supply."
