Our refinery has three Crude Distillation Units (CDUs), where the refining process starts. Crude is distilled into various fractions, each with an own boiling range, after entering the atmospheric distillation machines. To satisfy the required standards for product quality, the generated fractions undergo additional refinement in different units. In order to separate vacuum gas oil from vacuum residue, the majority of the atmospheric residue is transported for vacuum distillation.

High-quality, low-sulfur intermediate distillate products can be produced from heavy fuel oil components using the Hydrocracker, which uses the Unicracker Technology. After removing unwanted contaminants with vacuum gas oil and hydrogen in a hydrotreating reactor, they are catalytically cracked in the presence of hydrogen and catalysts through a high-temperature, high-pressure process.

Heavy, low-grade residual oils are processed by the Residue Catalytic Cracker (RCC) to produce fuel oil components, diesel, olefinic light ends, and gasoline. A fluidized bed of solid catalysts circulates quickly at extremely high temperatures between a reactor and a two-stage catalyst regenerator in this method. The MTBE Unit and Alkylation Unit receive light end olefinic products from the RCC in order to produce additional components for gasoline mixing.
