Major turnaround at Neste refinery to complete planned production structure change

In mid-August, Neste will begin a two-month shutdown at its refinery in Naantali, Finland. The major turnaround will complete the plan first introduced in 2014 to implement closer integration of the operations of the two Finnish refineries under uniform management. The Finnish refinery operations of Neste consist of four production lines at the Porvoo refinery, and one in Naantali.
