INA and MOL Group Successfully Commission New Unit at Rijeka Refinery

INA, a subsidiary of MOL Group, has successfully started up a new Delayed Coker Unit (DCU) at the Rijeka refinery as part of a major upgrade project valued at nearly €700 million. The unit achieved start-up after feedstock was introduced on September 1, 2026, and has since been operating continuously at approximately 70% of its design capacity. The successful commissioning allows the refinery to process heavy residues into higher-value products and enables the facility to process heavier crude grades.

The operational upgrade allows the refinery to achieve greater product efficiency, with the same volume of crude oil potentially yielding up to 30% more diesel. Furthermore, the new capacity eliminates the need for the facility to import vacuum gas oil (VGO), increasing operational flexibility and strengthening crude supply security for the region.
