Swedish refiner Preem Petroleum has completed repairs to and restarted two units at its 210,000 bpd refinery in Lysekil, Sweden.
Both the hydrogen production unit (HPU) and isocracking unit have resumed normal operations after a HPU furnace tube ruptured in March resulting in the shutdown of both units.
An inspection carried out during repairs to the ruptured furnace tube uncovered additional issues associated with the furnace requiring maintenance, which extended the units’ shutdown period by 3 weeks, Preem said.
During the shutdown Lysekil maintained normal operations with the refinery operating at 80-90% of its full capacity.
Preem said the shutdown had a $61 million impact on operating income for the first quarter.
