Oil Refinery has the following structure: 8 processing workshops, tankage facilities, feed tank, 5 stock tanks and 3 auxiliary shops.
Geological services has been successfully carried out within the territory of thr former Bashkir Autonomous Republic now Bashkortostan. 1953 the Ministry of oil industry adopted decision to build up and put into operation Novo-Ishimbayskiy oil refinery as part of concern No. 18. This plant was aimed to allow processing up to 3 mln. tn of sulfur crude oil of oil deposits Romashkinsiy, Shpakovskiy and Ishimbaiskiy.
The history of the plant development can be divided into a few stages:
The 1. Stage covers the period from 1955 to 1960.
In 1955 desalination unit ELOU-1, atmospheric and vacuum crude unit AT-1, 2 units of catalytic cracking 43-102, gas-fractionation plant were put into operation.
1956 - Commissioning of desalination unit ELOU-2,3, 3 units of AVT by designed capacity 3 mln.tn, 2 unit of thermo cracking . The first commercial product was achieved.
1957 - Commissioning of desalination unit ELOU-4, atmospheric and vacuum crude unit AT-2 for hydrogenation product vapor phase hydrogenising distillation in order to obtain gasoline and special fuel.
1958 - Commissioning of atmospheric gas fractionation plant, sulfuric acid alkylation unit, the 3-d catalytic cracking unit, hydro forming unit.
1959-1960 - putting into operation the following units: desalination unit ELOU-5, AVT-4 be design capacity 2 mln. tn/year and gas-fractionation plant GFU-2.
The 2nd Stage covers the period from 1961 to 1974.
When the large-scale oil deposits in the sound-western part of Bashkiria were developed the oil refinery was supplied by crude oil from Arlan deposit. This marked the beginning of a new stage in the history of the plant - sour oil processing development. At initial step the crude oil was delivered by rail way. In 1965 pipeline Kaltasy-Salavat was commercialized. To realize sour oil processing the reconstruction works on primary distillation of crude oil and thermo cracking units were done as well as the design and construction of secondary distillation of crude oil unit were started.
1965-1975 putting into operation one at a time the following units: hydrotreating units Л-24-6, Л-24-7, light hydrocracking unit polymerization unit, platformer unit Л-35-6/300, precision fractional distillation unit by 1500 kt/y, capacity catalytic reforming unit ЛЧ-35/11-600.
The 3d stage covers the period from 1975 to 1980.
A new step in the history of oil refinery started with the commissioning of Orenburg gas deposit - gas condensate processing, which involved at its initial stage reconstruction of thermal cracking units, stabilizer АГФУ for steam distillation, hydrotreating unit ЛЧ-24-7 for gasoline fraction hydrotreatment. With gas condensate processing development to commercial level the production capacities of oil crude are also increasing; retrofitting of primary and secondary processing capacities are required. In 1978 the condensate crude processing production complex put into operation. In marked an important event in the history of plant. The production complex included gasoline hydrotreatment unit by capacity 2 mln. tn\y and catalytic reformer by capacitu 1 mln. th/y. The total output of oil crude increased from 8 mln. th/y to 12,2 mln. tn/y. Following commissioning of a.m. technological units made it possible to process a total quantity crude oil from Orenburg oil deposit, to increase low-sulfur diesel fuel output as well as high-quality brands of gasoline.
The 4th stage covers the period from 1980 to 2003.
In the earlier 1980 the composition of crude oil for oil refinery changed. Crude oil supplies are reduced; gas condensate supplies from Orenburg deposit are decreased. The governmental take a decision to compensate the hydrocarbon material shortage by gas condensate from Karachaganak deposit (КГК).
That marked a new stage in the history of oil refinery. Initially the Karachaganak condensate was developed by available units of ELOU-1,4, ЕЛ-3, АГФУ-1. At the same time the units were modernized for the new crude oil processing.
1990 - After reconstruction a new gas condensate process unit was put into operation by capacity 1,3 mln, tn/y.
1999- Construction and commissioning of a new unit ELOU-AVT-4 by capacity 4 mln. tn/y. for condensate processing marked the final stage of development of gas condensate from Karachaganak deposit. The total control system usage allowed bringing the process technology to an upper level. The units found be outdated were removed from production. When a new unit of ELOU-AVT-4 was brought into operation this increase gas condensate share in total volume of process raw materials was 43, 5 per cent in 2002.
The successive comprehensive development of the plant allows producing rival products. 2002 oil refinery received permission to produce the new brands of gasoline: Normal-80, Regular-91, Premium -95, Super-98, and 2001 - Regular -92, Normal -80, Regular-92.
2001 - To increase sales of light petroleum product automatic filling system for car fuel tanks has been set up. State of the art new gas condensate tank farm was introduced to provide stability of crude oil supply. The reconstruction works of the filling station were carried out in order to increase capacity of filling and discharging of oil products, gas condensate, and straight run gasoline.
The 5th stage through to present time.
Today oil refinery is capable to manufacture the following products:
nonleaded gasoline of Normak-80, regular-92, Premium -95, Super-98, pentane isopentane fraction, petrobenzene, petroleum toluene, kerosene absorbent, fuel oil, feedstock for oil road asphalt production, technical sulphur, oil asphalt.
Oil refinery continues to carry out updating the process technologies, modernization of units, integration of a new productions units. Currently the ОГ and КГ, Л-35.6, AVT-4, Л-16-1 were retrofitted. State- of -the- art
bitumen production unit is put into operation; visbreaking and catalytic cracking units are under construction. The tender was issued for alkylation, delayed coking, a new AVT-4 by capacity 4 mln. tn/y units.
