Research on production of special diesel fuel DO L-62 at Dung Quat Refinery for national defense and security

Abstract

The article presents the results of research on the commercialisation of special diesel fuel DO L-62 at Dung Quat Refinery according to TCVN/QS 1754:2014 to meet the fuel demand in the field of defense and security. Based on the review of technical documentation and the assessment of the impact of operating modes/parameters of the Crude Distillation Unit as well as the properties of crude oil feedstocks on product quality, the authors proposed optimal technological improvement solutions to produce the new DO L-62 product on the existing technological line of Dung Quat Refinery. In the 2022-2024 period, the Binh Son Refining and Petrochemical Joint Stock Company (BSR) under the Vietnam National Industry - Energy Group (Petrovietnam) produced and supplied approximately 70,000 m³ of DO L-62 special fuel to the Ministry of National Defence. The results of this research also contribute to promoting domestic production, reducing dependence on imported fuel supply, ensuring national energy security, and enhancing Vietnam’s self-reliance in producing fuel for defense applications.
