Crude Supply

• Until July 2006, the primary feedstock processed by the Mazeikiai Refinery was Russian crude oil shipped by the Druzhba Pipeline system. These supplies were supplemented by crude oil and other feedstocks delivered by railway.
• Mazeikiu Nafta also purchases for the Refinery truck shipments of crude oil produced in Lithuania.
• Currently the main deliveries of crude oil to the Mazeikiai Refinery come via the Butinge Oil Terminal.

Products Produced

• Gasolines:
• Diesel fuels
• Fuel oil
• Jet fuel JET A-1
• Liquefied petroleum gas
• Bitumen
• Elemental sulphur

Projects

• The Mazeikiu Nafta Residue Hydrocracker Project will reduce heavy products and boost middle distillates
• The project is scheduled to finish in 2024
• A previous project, Mazeikiu Refinery Project added a hydrocracking unit, expanded an FCC, upgraded a visbreaker and added a vacuum flash unit

Other Information

• The design capacity of the Mazeikiai Refinery is 15 million tonnes of crude oil per year.
• However, a lack of conversion units means that it only operates at 8 million tonnes of crude oil per year.
