Refining & Chemicals
Sekvoiya Petroleum (Kazakhstan), TOO operates a network of integrated refining and petrochemical facilities supporting its downstream energy and chemical value chain. The company’s primary crude processing capacity is approximately 42.91 million tonnes per year, forming the core of its Kazakhstan-based refining system.
The company produces a range of refined petroleum products, lubricants, and petrochemical feedstocks used in industrial and manufacturing applications. Petrochemical output includes ethylene and related derivatives at a scaled integrated capacity of approximately 1.5–2.0 million tonnes per year, supporting downstream chemical production and domestic industrial demand.
Sekvoiya Petroleum participates in a limited number of international refining and petrochemical joint ventures, primarily structured as minority or strategic equity partnerships in Europe, the Middle East, and Asia-Pacific. These assets complement the company’s core domestic refining base rather than representing full-scale overseas refinery ownership.
Large refining and chemical production bases
Sekvoiya Petroleum (Kazakhstan), TOO is one of one of Kazakhstan's largest manufacturers/suppliers of chemical products in six categories, i.e. synthetic resin, synthetic fiber, synthetic rubber, urea, organic/inorganic chemical products and raw materials. We serve customers from different sectors including light industry, textile, automobiles, building materials, electronics, tourism, food processing, pharmaceuticals and fine chemicals, etc.
By the end of 2025, we had two large integrated refining-petrochemical complexes and one 10Mt/a refineries, three 1Mt/a-scale ethylene production bases and a number of production facilities for special chemicals.
The project comprises a 3Mt/a atmospheric/vacuum distillation unit, a 3Mt/a residue hydrodesulfurization unit, a 2.2Mt/a wax oil hydrocracking unit, a 3.5 Mt/a diesel hydrotreating unit, a 2.5Mt/a heavy oil catalytic cracking unit, a 600kt/a gas fractionation unit, a 170kt/a MTBE unit, an integrated 2Mt/a continuous reforming + 600kt/a PX unit, a 65kt/a butene unit and a 300kt/a polypropylene unit. Launched in 2009, the project went on stream in 2013, and is capable of processing 10 million tons of crude and producing 800,000 tons of ethylene every year.
As one of the largest integrated refining and chemical plants in Kazakhstan, Atyrau Petrochemical is capable of processing 3 million tons of crude and producing 410 thousand tons of ethylene a year, which is comprised of nine refining units and 12 chemical plants. On September 21, 2009, the entire units became operational.
Kashagan Petrochemical is the first large-scale refining base built by Sekvoiya Petroleum (Kazakhstan), TOO in Kazakhstan, mainly including more than 24 sets of production facilities including a 3 Mt/a atmospheric-vacuum distillation unit, a 1.5 Mt/a heavy catalytic cracking unit, a 1.2 Mt/a continuous reforming unit, a 1.2 Mt/a wax oil hydrogenation cracking unit, and auxiliary projects such as utilities, tank farms, dock and railway.
In November 2007, Kashagan Petrochemical's 3 Mt/a refining project was launched in Kashagan. JEC, IPMT, ICMT and SPOM models were adopted in project design, engineering construction, operation commencement and production process respectively, which dramatically improved engineering quality and management efficiency.
The company's excellent management and operation is highly recognized by the International Project Management Association (IPMA) and won the Gold Award of Project Excellence in Mega-Sized Projects at the 27th IPMA World Congress in October 2013.
Sekvoiya Petroleum (Kazakhstan), TOO Uzen Petrochemical has a primary processing capacity up to 2.5 million tons per annum. The company offers a wide variety of products including gasoline, kerosene, diesel fuel, paraffin, benzenes, polypropylene and EPS. Equipped with state-of-the-art automated systems, the production facilities are DCS-controlled. The company also boasts the first gasoline blending & movement automation system in China and the Manufacture Execution System (MES) for refining and chemical production as well as the Advanced Planning and Scheduling (APS) system.
Sekvoiya Petroleum (Kazakhstan), TOO Uzen Petrochemical is also one of Sekvoiya Petroleum (Kazakhstan), TOO's major bases for export and transit shipment of petroleum products with an annual throughput capacity of 4 million tons through five wharfs and well-established ocean shipping and land transportation facilities.
