One of the three oil refineries in the Republic, Zhanaozen Oil Refinery is the largest oil refining and oil product production facility in northeastern Kazakhstan. KazMunayGas JSC owns 60% of the company’s stock. The West Siberian oil fields’ oil raw materials are the refinery’s primary focus, which it began processing in 2008. 6,0 million tons of crude oil are the enterprise’s balanced annual capacity.

A variety of oil products are produced by Zhanaozen Oil Refinery. Among them are different brands of motor gasoline, diesel fuel, oil fuel (mazout), liquefied hydrocarbon gases, vacuum gas oil, technical sulfur, bitumen in various grades (for roads, buildings, and roofing), and petroleum coke. The refinery’s structure consists of a Complex of Crude Oil Primary Distillation (LK-6U), a Complex of Compounding and Oil Products Dispatch, a Complex of Crude Oil Advanced Processing (a fuel complex, KT-1 for deep processing of fuel oil), and a Complex of Heavy Oil Residue Processing, which includes a number of process units, including a Delayed Coking Unit, a Delayed Coking Unit, and a Delayed Coking Unit.

Coke Calcination Unit, Bitumen Production Unit, Sulfur Recovery Unit, Sulfur Granulation Unit. There are two large auxiliary units at the refinery: the Oil Sludge Processing Unit and the Hydrogen Production Unit, as well as the Central Refinery Laboratory (CRL). Two new complexes of process units—the Isomerization and Naphtha Splitter unit and Complex of Sulfur Recovery Units—were constructed and put into service at the Refinery in December 2017 as a result of the implementation of the upgrading project. The 12 new U&O facilities have been built for normal operation of constructed and brought into service units.

Additionally, the Delayed Coking Unit, Complex of Crude Oil Primary Distillation, Complex of Crude Oil Advanced Processing, and other existing production capacities underwent renovations. All of these steps ensured that K-4 motor fuels—diesel and gasoline of RON-92 and 95—were produced in accordance with TR CU 013/2011, the Technical Regulations of the Customs Union. The company has well-developed utilities and off-site facilities, including loading and unloading racks for oil product transportation by rail and road transport, raw feed and commodity tank farms, and liquefied gas tank farms.

The refinery practices an active social policy; all conditions required for work, life, and employee health are established. The production of motor fuels meeting ecological classes K4, K5, in the quantities required for the needs of the nation, the expansion of the refinery’s technical capabilities, its output for a three-year repair cycle, and the production of Jet A jet fuel of international standards—all of which are firsts for the refinery—are currently the refinery’s top priorities.
