Dung Quat refinery prioritizes maximum production of jet A-1 aviation fuel

Currently, BSR is operating the entire refinery at an equivalent capacity of approximately 123.5%, with several key process units running above design capacity to increase output of high-demand products such as RON 95 gasoline, diesel (DO), and Jet A-1 fuel. Among them, the Kerosene Treating Unit (KTU) plays a critical role in meeting the rapidly increasing demand for aviation fuel.

On April 1, 2026, at Dung Quat Refinery, the refinery management convened a meeting with the participation of functional divisions, technology licensors, and O&M consultants to evaluate plans for increasing the capacity of the KTU. The meeting focused on a comprehensive review of technological, operational, and safety conditions in preparation for testing capacity increases from 140% to 144%, and subsequently to 145%.

According to reports presented at the meeting, the KTU has been gradually ramped up and has been operating stably at 144% capacity since 11:00 AM on March 30, 2026. Previously, in 2025, the unit operated safely and stably at an average capacity of approximately 140%, producing 509,042 tons of product and meeting over 30% of domestic aviation fuel demand (approximately 1.5 million tons of Jet A-1 per year).

Maintaining stable operations at 144% capacity marks a significant milestone, demonstrating BSR’s capability in mastering technology, optimizing operations, and ensuring effective coordination among technical, operations, and maintenance teams. Throughout this process, all operating parameters have been strictly controlled; product quality has fully met international standards; and safety and environmental requirements have been consistently ensured.

On this basis, the refinery has agreed to further increase the KTU capacity to 145%. This represents the next step in the capacity optimization roadmap, aiming to fully utilize equipment capabilities while promptly meeting rising aviation fuel demand amid global energy market volatility.

To support evaluation and operations, technical teams have prepared comprehensive documentation, including Process Flow Diagrams (PFD) and operational snapshot data of the CDU complex, particularly at column T-1102, as well as the KTU unit. These data provide refinery management and experts with a comprehensive view of the interconnections among process units, enabling informed decisions to ensure optimal efficiency and safety.

Speaking at the meeting, Mr. Cao Tuan Si, Director of Dung Quat Refinery, emphasized that leveraging the experience and expertise of the petroleum workforce, BSR’s technical teams have proactively assessed operational capabilities, equipment performance, and safety conditions to optimize unit capacities, meet market demand, ensure energy security, and enhance business efficiency.

“The stable operation of the KTU at 144% capacity since March 30, 2026, demonstrates the refinery’s technological mastery and operational flexibility. As we increase capacity to 145% from 4:00 PM on April 1, 2026, stricter control of operating parameters is required to ensure absolute safety, equipment stability, and efficiency,” Mr. Cao Tuan Si stated.

The proactive increase in KTU capacity is one of the key solutions enabling Dung Quat Refinery to flexibly respond to market fluctuations, ensure fuel supply - especially aviation fuel - for the economy, and reaffirm its role in maintaining national energy security amid current challenges.
