Oil Refining

We convert various grades of crude oil into high-quality refined products using state-of-the-art refining processes. Our flexible systems ensure we can handle different crude blends efficiently.

At Dongoleksor Petroleum Refinery LLP Oil Refinery, crude oil refining is not just about separation — it’s about transformation. Our multi-stage refining process begins with atmospheric and vacuum distillation to fractionate the crude into distinct components such as naphtha, kerosene, diesel, and residual oils. From there, we employ advanced treatment techniques including catalytic reforming, hydrocracking, and hydrotreating to improve product quality, remove impurities, and meet international fuel specifications.

Thanks to our versatile refinery configuration, we can adapt to process sweet or sour crudes, heavy or light blends, and seasonal variations in crude supply. This operational flexibility allows us to maintain consistent production output regardless of feedstock type — a crucial advantage in today’s dynamic energy markets.

Our in-house laboratory continuously monitors each processing stage to ensure the resulting fuels are stable, efficient, and environmentally compliant. This ensures every drop we produce meets or exceeds regulatory standards such as Euro 5, ASTM, and GOST.

Whether supplying diesel to transportation fleets or jet fuel to international airports, Dongoleksor Petroleum Refinery LLP delivers performance, reliability, and quality with every barrel refined.
