The Crude Distillation Units (CDUs), of which our refinery has three, are where the refining process gets started. Crude is distilled into various fractions, each of which has a distinct boiling range, as it enters the atmospheric distillation units. To achieve the stated product quality standards, the resulting fractions are further refined in a variety of units. Vacuum distillation is used to separate vacuum gas oil and vacuum residue from the majority of the atmospheric residue.

The Catalytic Reformer Complex transforms the low-octane naphtha from CDUs into high-octane reformate for making gasoline.

The Hydrocracker, using the Unicracker Technology, enables the synthesis of intermediate distillate products from heavy fuel oil components that are high quality and low in sulfur. In order to eliminate unwanted impurities, vacuum gas oil and hydrogen are transferred through a hydrotreating reactor. Then, these contaminants are catalytically broken by a process of high temperature and pressure in the presence of catalysts and hydrogen. Some of the unconverted oil at the bottom of the fractionator is recycled back to the hydrocracking reactor to boost conversion before products from the hydrocracking reactor are sent to distillation columns for product separation. Hydrogen’s inclusion in the hydrocracking process yields excellent products with very low sulphur content that don’t need any additional processing. The primary products are lighter substances like naphtha, kerosene (jet fuel), and low-sulfur car diesel. The Sulphur Recovery Unit is where hydrotreated sulfur compounds are recovered before being turned into flaked sulfur.

By thermally upgrading heavy atmospheric and vacuum leftovers into distillates and fuel oil with a low viscosity, the Visbreaker unit gives SRC greater flexibility to respond to shifting market demands.

Heavy, low-grade residual oils are processed by the Residue Catalytic Cracker (RCC) into a variety of products, including olefinic light ends, gasoline, diesel fuel, and fuel oil components. In this procedure, a fluidized bed of solid catalysts circulates quickly and at extremely high temperatures between a reactor and a two-stage catalyst regenerator. The MTBE Unit and Alkylation Unit get feed from the RCC’s light end olefinic products in order to produce more components for gasoline mixing. While the Alkylation Unit creates Alkylate, the MTBE unit creates MTBE (Methyl-Tertiary-Butyl-Ether), a high octane blending component. The combined output of these two units, along with a new Gasoline Desulfurization Unit that was put into service in 2017, strengthens SRC’s capacity and flexibility to produce premium products like high octane motor gasoline and diesel fuel without lead additives, giving SRC an advantage in satisfying the region’s expanding demand for environmentally friendly transportation fuels.

The Cogeneration Power Plant (Cogen) Facilities, which were put into service in 2017, have the ability to burn natural gas to produce electricity and high pressure steam for SRC’s use. The Cogen greatly increases energy efficiency and lowers greenhouse gas emissions by using sustainable energy.

SRC has a large amount of storage space with more than 70 tanks for crude, blending ingredients, and finished goods.

Our refinery complex has extensive berthing facilities including 7 berths handling loading and discharge of crude and refined petroleum products. The berths can accommodate ships of up to 387,000 deadweight with maximum length overall of 355 meters and 21 meters loaded draft.
