PROMFINSTROY JSC and Ryazan Oil Refining Company are long—standing and strong partners in the construction, reconstruction and repair of oil refining facilities. For more than 16 years PROMFINSTROY has been performing a complex of works related to the construction and modernization of production for RNPC.
The beginning of this long-term cooperation should be considered 2002, when PROMFINSTROY received the status of a general contractor for capital construction and major repairs for RNPC. At the same time, an unprecedented project was launched for the construction of a vacuum gas oil hydrotreating complex, which included several large-scale facilities:
All these facilities were commissioned on time, scheduled for 2006. At the same time, work was underway on the construction of a combined unit for the production and reduction of sulfuric acid and sulfuric acid alkylation with an isomerization unit of normal butane.
In subsequent years, PROMFINSTROY JSC continued the construction of technological facilities for the Ryazan oil refinery, and also started a number of reconstructions for the enterprise, for example, LCH 24/6 and LCH-24/7 installations. Until 2016, PROMFINSTROY inclusive:
In 2017-2018. PROMFINSTROY JSC has started, along with reconstructions, the overhaul of RNPC facilities. This includes the overhaul of the AT-6 unit with the VT-4 unit, and the reconstruction of the 19/5 bitumen raw material mixing unit, and the modernization of the latching, regeneration and reagent supply system at the reforming unit. Projects for the reconstruction of the ELOU-AT-6 primary oil refining unit have also been successfully completed.
In addition, PROMFINSTROY JSC on an ongoing basis oversees all requests for the current repair of the Ryazan oil refinery, maintaining its technological installations in working order and carrying out scheduled preventive work.
Today, the Ryazan Oil Refining Company is a powerful enterprise that processes more than 18 million tons of oil per year. More than half of the petroleum products produced by RNPC are light, and the processing depth reaches 73.1%.

2012-2014 The main goal of the project is to improve the quality of gasoline through the use of isomerizate, which significantly reduces the content of harmful substances in the exhaust. The launch of the Izomalk-2-LIN-800 plant made the produced fuel that meets high technical requirements even more competitive.
The project provided for the construction of an intermediate raw materials park, a centralized operator room, inter-shop communications, engineering networks and communications, and the implementation of vertical planning. The construction of the facilities took 27 months. In connection with the work in the conditions of the operating enterprise, special requirements were imposed in the field of industrial safety and labor protection.
2004-2006 The main task of the installation is to obtain an absolutely pure base component for high-octane fuel, in which there is no aromatic component, and the sulfur content is minimal. After commissioning of the sulfuric acid alkylation unit with a normal butane isomerization unit, the efficiency of the VGO complex doubled. And currently it is the basis for the production of key commercial products of RNPC.
One of the most difficult operations during this period of construction was the assembly of the R—3000 reactor and the E-3020 tank, manufactured by the South Korean firm DOOSAN Mecatec Co.,Ltd., as well as the installation of one of the tallest columns with a height of 84 meters.
2002-2005. The main goal of the project was to increase the efficiency of oil refining by extracting light oil products from the vacuum gas oil remaining after primary oil refining. The complex includes five technological installations, one of which produces hydrogen from natural gas, the other uses the byproduct hydrogen sulfide, which is processed into sulfuric acid.
During the construction process, 10767 piles were driven, 50552 cubic meters of concrete were laid, 13550 tons of metal structures and 7930 tons of technological pipelines were installed, 644 pieces of equipment and about 7000 units of instrumentation and equipment were installed. In total, 130,000 m2 of surfaces were painted, 24,000 m3 of thermal insulation were laid, 782,000 meters of electrical cable were laid. During the implementation of the project, 9,284,175 man-hours were worked, and the number of workers at the site was more than 2,000 people.
The year 2004 was remembered for the unique installation at the vacuum gas oil hydrotreating plant of two reactors with a height of 39 meters and a weight of 290 tons each. Promfinstroy delivered a crane with a lifting capacity of 750 tons from Finland to lift the reactors. When installing the rectors in the design position, three cranes with a total lifting capacity of 1,450 tons were simultaneously involved.
