Oita Refinery
The Oita Refinery, the Only Refinery in Kyushu, Meets Diverse Energy Needs

The Oita Refinery covers the diverse energy demand of the Kyushu area through its three core businesses of oil refining, petrochemicals, and electrical power. As an integrated energy company, it not only manufactures and provides a steady supply of petroleum products such as high quality LPG, naphtha, gasoline, kerosene, diesel fuel, and fuel oil, but it also produces petrochemical product raw materials such as xylene, paraxylene, benzene, and petrochemical naphtha and performs electricity business operations, helping meet local energy demand.
Message from the Refinery Manager

Greetings from the ENEOS Oita Refinery.
Our refinery is the southernmost refinery in the ENEOS Group and the only refinery in Kyushu. We have a dock where large tankers, up to 300,000 tons, can directly berth, and we cover the diverse energy demand of the Kyushu area through our three core businesses of oil refining, petrochemicals, and electrical power.
The motto of our refinery operations is "Safety is our highest priority," and we strive to ensure safe, steady operations. We carry out a wide range of environmental activities and work to exist in mutually beneficial harmony with the local community through social contribution activities such as ENEOS Oita Support Team and ENEOS-Dowa-no-Mori activities.
"Always Cherishing the Nature of Our Home, Oita"
Since we first began operations, this concept has guided the Oita Refinery’s day-to-day activities, earning the love of the local community. The Oita Refinery looks forward to your continued support into the future.
