Employees walk inside the premises of Poland's PKN Orlen's oil refinery Mazeikiu Nafta in Mazeikai, 300 km (186 miles) from the capital Vilnius February 5, 2008. PKN Orlen said on Tuesday it aimed to boost the capacity of its Lithuanian refinery to 11 million tonnes a year, though it was still running below full capacity after a key fire-damaged unit was repaired.
