Production & facilities
From primary crude oil distillation through deep conversion and heavy residue processing, supported by hydrogen production, water supply and a central refinery laboratory.
Process chain
The refinery is configured as a full conversion chain: crude oil is separated, the heavier fractions are upgraded into light products, and residues are converted rather than sold as low-value fuel oil.
Oil raw materials from the West Siberian oil fields arrive at the raw feed tank farm.
Complex of Crude Oil Primary Distillation (LK-6U) separates crude into straight-run fractions.
Fuel complex KT-1 deep-processes fuel oil, converting residues into light products.
Delayed Coking, Coke Calcination, Bitumen Production and Sulfur Recovery Units.
Blending of commercial grades, tank storage and dispatch by rail and road transport.
Main complexes
The structure of the refinery includes a Complex of Crude Oil Primary Distillation (LK-6U), a Complex of Compounding and Oil Products Dispatch, a Complex of Crude Oil Advanced Processing and a Complex of Heavy Oil Residue Processing.
Separates crude oil into straight-run fractions — gasoline, kerosene and diesel cuts plus vacuum gas oil and residuum — which feed every downstream unit. The complex was revamped as part of the upgrading project to increase throughput and improve fractionation quality.
Carries out blending of finished commercial grades to the required specifications and dispatches products to the tank farms and loading facilities. It is the link between process units and the customer.
A fuel complex — KT-1 for deep processing of fuel oil. It converts heavy residue into additional light products, raising the refinery's conversion depth. The complex was revamped during the upgrading project.
Includes several process units such as the Delayed Coking Unit, the Coke Calcination Unit, the Bitumen Production Unit, the Sulfur Recovery Unit and the Sulfur Granulation Unit — converting residues into petroleum coke, bitumen and granulated technical sulfur.
Process units
Converts heavy residue into gas oil fractions and petroleum coke using the delayed coking process. Revamped as part of the upgrading project to strengthen residue conversion.
Further processes raw petroleum coke from the coking unit, raising its carbon quality for industrial and metallurgical applications.
Produces bitumen of several grades — construction, road and roofing — for road building and industrial use across Kazakhstan.
Recovers sulfur from process gas streams, cutting emissions. Commissioned as part of the new Complex of Sulfur Recovery Units in December 2020.
Turns recovered sulfur into granulated technical sulfur — a safe, handleable and marketable by-product for transport and export.
New complex commissioned in December 2020 that lifts the octane quality of the gasoline pool through isomerization and naphtha fractionation.
Auxiliary units
At the refinery there are a Hydrogen Production Unit and an Oil Sludge Processing Unit, as well as large auxiliary units — the Water Supply and Sewerage plant and the Central Refinery Laboratory (CRL).
Supplies hydrogen required for hydrotreating and upgrading, underpinning the production of low-sulphur fuels.
Handles oil sludge streams as part of the refinery's environmental and resource-efficiency programme.
A large auxiliary unit ensuring water supply and sewerage for normal operation of the whole complex.
Carries out quality control of raw materials, intermediate streams and finished commercial products.
The enterprise has well-developed Utilities & Offsite facilities:
Storage capacity for crude oil raw feed and finished commercial products.
Dedicated storage for hydrocarbon liquefied gases produced by the refinery.
Racks for oil products transportation by rail and road transport.
Upgrading project
As a result of the upgrading project implementation, two new complexes of process units were built and commissioned in December 2020 at the Refinery: the Isomerization and Naphtha Splitter unit and the Complex of Sulfur Recovery Units.
