OMV Aktiengesellschaft,  Vienna, will delay restart of its 9.6-million tonnes/year        refinery at the operator’s  integrated complex in Schwechat, Austria, following an early June upset that  occurred at the tail end of the 2022 turnaround.
An unidentified mechanical incident  occurred on June 3 that damaged the refinery’s main crude oil distillation unit  and caused slight injuries to two individuals at the site, OMV said in a  release.
As a result of the incident, scheduled  maintenance at the refinery, which has been ongoing since Apr. 19, will be  partially delayed, according to the operator.
An assessment of damage remains  under way, and a definitive timetable for duration of the extended shutdown has  yet to be determined, OMV said.
Without disclosing further details  surrounding the incident, the operator said it will work closely with its  customers and suppliers to mitigate any impact on product availability.
Confirmation of the June 3 incident  follows OMV’s end-May announcement that it was completing final works and  checks of the turnaround and preparing systems for restart.
In a May 31 release, the operator said  refinery staff was in the process of slowing returning equipment to operation  at the site, which potentially would result in flaring.
At the time, overall production was  scheduled to resume once all system parts were safely in “warm” mode and  integrated back into the production process.
According to OMV’s website, the 2022  turnaround only involved the refining portion of the Schwechat complex, which  also produces ethylene, propylene, butadiene, and aromatics. In addition to  maintenance and inspection of the refining plants, OMV said it also was using  the turnaround period to execute modernization works that would prepare the  refinery—Austria’s only—for a reduced-emissions future.
Schwechat’s petrochemical plants are  scheduled for routine turnaround activities in 2023, the operator said.
