Antipinsky Oil Refinery CJSC was established in July 2004 in the Tyumen Region accounting for the major part of Russia’s oil and natural gas reserves. The enterprise is unique in that it is the first oil refinery independent from vertically integrated oil companies to have been built from scratch in over 30 years, whose capacity exceeds 8 million tons per annum and the quality of diesel fuel produced meets Euro-5 standard since 2015. In the near future, the refining depth will come to 94% and the production of Euro-5 compliant gasoline will be commenced.
As the construction of any refinery with a maximum possible oil refining depth producing a complete range of high-quality engine fuels requires significant capital investments, refineries are built in several workflow phases. Each phase implies the organization of a complete production cycle making it possible to refine oil and ship a certain range of oil products of agreed quality to consumers. This is the development path chosen by the Antipinsky Oil Refinery CJSC.
The refinery’s Workflow Phase I of 400 000 tons per annum design capacity was commission in November 2006. As a result of the revamping undertaken, its capacity as of 2008 totalled 740 000 tons per annum.
In May 2010, the refinery’s Workflow Phase II with the crude oil throughput capacity of 2.5 MTPA was commissioned. As part of the modernization undertaken at the end of 2012, its capacity reached over 3.3 MTPA enabling the refinery to increase its total refining capacity to 4.0 MTPA in 2013.
Parallel to the construction and commissioning of its workflow phases, Antipinsky Oil Refinery CJSC acquired and renovated Antipino railway station, next to which the refinery’s Finished Product Section (FPS) was built. It is intended for the shipment of light petroleum products (gasoline, diesel fuel) by rail.
The commissioning of the Finished Product Section increased the refinery’s total petroleum product loading capacity to 8 MTPA (3 million tons basic capacity + 5 million tons FPS capacity). In January 2014, ELOU-AT-3 unit with the capacity of 3.7 MTPA (+ the unit’s 10% reserve refining capacity) was commissioned increasing the refinery’s total capacity to over 8 MTPA (7.74 MTPA – nameplate capacity of the three units + 0.37 MTPA reserve capacity of ELOU-AT-3 unit). Moreover, modern 5-stage wastewater treatment facilities and additional crude oil and commercial-grade diesel fuel tank farms were built marking the completion of the first stage of Workflow Phase III.
At Stage 2 of Workflow Phase III, in order to bring diesel fuel quality to Euro-5 standard (with sulfur content not exceeding 10 ppm) and ensure necessary pour point with the possibility to manufacture winter and Arctic grade diesel fuels, a hydrotreating unit (the licensor and developer of the basic design is Haldor Topsoe(Danmark)) was built. To ensure the operation of the hydrotreating unit, hydrogen generation and gas treatment shops, as well as an elemental sulfur production shop (with a granulation module) were built.
The second stage was implemented in June 2015, when the diesel fuel hydrotreating unit produced its first Euro-5 diesel fuel as part of pre-commissioning works.
Moreover, the construction of the LPG storage facility was completed. The storage is intended for shipment of PA and PBA commercial-grade liquefied motor gases produced by ELOU-3 unit. The LPG storage throughput capacity is 25,000 tons per annum, storage capacity is 500 m³.
At Stage 3 of Workflow Phase III, scheduled to be completed by 2015, the oil refining depth will be increased to 94% by the commissioning of the combined deferred tar carbonization unit with a fuel oil vacuum distillation module. Diesel fuel yield will eventually grow up to 50% of the total refining volume. The process licensor and basic design developer is Foster Wheeler (USA). Coke, as the end product of tar coking, is in high demand in the metallurgical industry.
The installation of heat exchangers, air cooling units, process equipment hookup, pre-assembly of process furnaces are currently underway. The unit’s structural steel has been erected by more than a half, the pumping equipment assembly has been almost completed.
Further, also as part of the 3rd stage, a second diesel fuel hydrotreating unit (with the feed capacity of 1.01 MTPA; total maximum feed capacity: 3.61 MTPA) will be commissioned.
Switching over to the production of high-octane Euro-5 gasoline with octane ratings of 92, 95 points measured using the research method will be effected at the 4th stage of Workflow Phase III by the commissioning of a gasoline reformer with continuous catalyst regeneration and an isomerization unit.
To implement the combined high-octane gasoline unit construction project, in June 2015, as part of the XIX Saint Petersburg International Economic Forum, Sberbank of Russia JSC and Antipinsky Oil Refinery CJSC entered into a non-revolving credit facility agreement for the amount of RUB 15.173 bn. On the part of Sberbank of Russia, the document was signed by the Maxim Poletaev, First Deputy Chairman of the Management Board, on the part of Antipinsky Oil Refinery CJSC, by Dmitry Mazurov, Chairman of the Board of Directors.
The construction of the unit aims to cover AI-95 motor gasoline shortage in the Tyumen Region and partially in the Urals Federal District and will help to create additional competition for major petroleum products market players to curb the price growth and improve the region’s environmental condition by reducing sulfur and benzene content in motor gasoline.
The refinery’s development plans for 2017 - 2018 include the construction of a vacuum gasoil hydrocracking unit with the capacity of 2.7 MPTA, which will use as feed the refinery’s own vacuum gasoil and heavy gas oil produced by coking from the fuel oil deep conversion unit.
After the completion of all the development stages, the refinery will start producing a wide range of petroleum products, in particular, Euro-5 compliant А-92 and А-95 gasolines, Euro-5 diesel fuel (of summer, winter and Arctic grades), petroleum coke and granulated sulfur.
When building new and upgrading its existing facilities the Antipinsky Oil Refinery pays special attention to minimizing the environmental footprint of its production process – these issues are an indispensable part of the refinery’s economic activity management system.
Therefore, simultaneously with the commissioning of the third unit, we have launched state-of-the-art five-stage water treatment facilities.
Russian- and foreign-made equipment complex provides for complete biological treatment of industrial and storm waters, as well as domestic wastewaters. Wastewater is treated in multiple stages: pre-treatment, physical and chemical treatment, biological treatment, advanced treatment and decontamination, dewatering of trapped petroleum products, watered residue and surplus activated sludge.
The refinery management creates the conditions enabling it to openly demonstrate the enterprise’s environmental responsibility. In July 2014, the Antipinsky Oil opened an Environmental Liaison Office, which can provide information on the ecological situation around the refinery at any time.
Thus, the Antipinsky Oil Refinery is surely and gradually turning into one of the most modern, hi-tech and safe enterprises of the Russian oil refinery industry.
