In 1966, the Kirishi refinery was put online. Since then, the company has been the main supplier of petroleum products for Saint Petersburg, Leningradskaya, Novgorodskaya and Pskovskaya oblast.
To improve product quality, reduce operation costs, ensure occupational health and safety and protect the environment, an innovative strategy is being steadily implemented by the company, whereby the refinery processes and production capacities are being modernized in phases. The degree of process automation is currently over 85%.
At the time of its integration in PJSC «Surgutneftegas», the refinery had a throughput of 15 million tpy. Technical revamps and reconstructions of primary oil processing units increased the throughput to 21 million tpy.
December, 1994 – the waterproofing, roofing and soundproofing roll materials and hot-applied bitumen-polymer compounds plant was put online at LLC «KINEF».
1994 – The sanitary laboratory of the Kirishi refinery was among the first to be accredited for compliance with the Analytical Laboratories Accreditation System’s technical competence requirements.
1996 – linear alkylbenzene (LAB-LABS) production complex was put online, providing the base for synthetic detergents with biodegradability of 95%.
1999 – The Gas Fractionation Unit was revamped, which allowed for adding a feed purification unit to remove hydrogen sulfide and switching the process to a distributed control system (DCS).
2001 – Elemental Sulfur Recovery Unit was modernized, increasing the overall conversion ratio to 96%.
2000 – A quality management system was implemented in accordance with ISO 9000 international standards. From March 2003, the quality management system is based on the process approach. At present, the company's management is committed to building and restructuring the management system in accordance with the new version of the GOST R ISO 9001-2015 "Quality management systems. Requirements" standard based on ISO international standards.
2003 – Catalytic Reformer Unit LCh-35-11/600 was revamped to ensure continuous and fail-safe operation. The state-of-the-art equipment allowed for decreased fuel gas consumption and an optimized process scheme.
2004 – Parex-1 Unit revamped.
2005 – “Isomalc” technology was implemented at the Unit L-35-11/300. The high efficiency of the Isomalk-2 technology enabled the refinery to produce high-octane Euro-4 fuels.
2006 – Orthoxylene and paraxylene production unit was revamped, including replacing F-101 Heater, recuperator, and field instruments, and switching to DCS-based operation.
A new package for benzene rich cut separation by fractionation from reforming catalyzate was commissioned at the mixed xylenes separation unit as per LLC «Lengiproneftekhim» design, enabling the reduction of automotive gasolines benzene content down to 1% vol. and their compliance with Euro-5 requirements. Equipment, instruments and process control systems were partially replaced.
2007 – equipment upgrade at ELOU-AVT-2 Primary Crude Oil Processing Unit yielded significantly reduced energy consumption.
LG-24/7 Unit for Hydrotreated Stable Diesel Fuel and Kerosene Components Production was upgraded with new equipment for the 1st stream and new field instruments, and fully switched to automated process control. This led to a reduction of product sulfur content from 2000 ppm to 50 ppm.
2010-2012 – Elementary sulfur production unit was expanded. Block 1 was revamped, including the installation of a third catalytic stage to achieve sulfur conversion up to 98% and the replacement of the generating reactor with a new one. Block 2 was designed to process hydrogen sulfide gas coming from L-24-10/2000 Unit under construction.
2012 – GTC-Technology process for aromatics extractive distillation was introduced at the Mixed Xylenes Distillation Unit in order to produce commercial benzene with purity not less than 99.9% from benzene rich cut 62-85 °С.
Unit L-24-10/2000 was put online designed for processing a mixture of atmospheric gasoil and straight run diesel cut and visbreaker gasoline coming from the hydrocracker complex. Unit L-24-10/2000 significantly increased the quality of diesel fuel output. The refinery additionally produces over 800 tpy of ultra-low sulfur fuel by processing atmospheric gasoil feed that was previously used for heavy fuel oils production.
In December 2013, the construction of the Advanced Oil Refining Complex on the basis of vacuum gas oil hydrocracking was completed. The main unit of the Complex – the atmospheric residue deep conversion unit – includes the vacuum distillation (4900 thousand tpy), hydrocracking (2900 thousand tpy), visbreaking (1900 thousand tpy) and hydrogen production (112 thousand tpy 100% hydrogen) sections as well as the waste-water recovery and sour water stripping plant with the capacity of 570 thousand tpy.
The unit can be operated in three modes: for maximum diesel fuel production, maximum kerosene production or producing both at maximum capacity. The feed (vacuum gas oil) conversion rate of the hydrocracking unit is 99%.
The ramping up of the atmospheric residue deep conversion unit has enabled the refinery to produce over 2 million tpy of high quality petroleum products (diesel fuel, kerosene) with ultra low sulfur content and increase the raw materials base for high octane gasoline production by 600 thousand tpy.
The construction of the Klaus elemental sulfur recovery plant with a capacity of 75 thousand tpy has been completed. The new unit is capable of producing high quality granulated sulfur with hydrogen sulfide content below 0.001%. The process has a 99.9% hydrogen sulfide conversion rate.
The Advanced Oil Refining Complex at LLC “KINEF” is capable of producing petroleum products in accordance with class 5 environmental and quality specifications.
Simultaneously with the construction of Advanced Oil Refining Complex, a full set of measures were implemented to protect the environment. A new line of treatment facilities with a capacity of 1000 cubic meters per hour has been commissioned in the 1st industrial sewage system.
To increase the capacity and ensure stable quality of wastewater treatment, modernization of the flotation treatment unit of the first industrial sewage system with overall capacity of 3000 cubic meters per hour was carried out. The refinery's ecology department plans to modernize the flotation treatment node of the second industrial wastewater treatment system in the coming years.
The bio- and oil sludge decontamination unit, unique within the industry, has been commissioned. Its operation in the coming years will ensure an 80% reduction of disposed waste volume and an 11% reduction of hydrocarbon emissions from exposed surfaces of sludge storage pits.
In December 2013, an automated on-spot railway tank loading system for light oil products was commissioned at the Manufacturing Production Shop No.46.
2014 – Shop No.9 elemental sulfur production unit sulfide stripper was commissioned. 3D modeling was used at the refinery for the first time during its construction.
In 2014, AVT-2 unit was revamped to meet the technical development plan.
In late 2015, the first diesel fuel hydrotreatment unit L-24/6 was recommissioned after a complete revamp and now allows KINEF to continuously produce class 5 diesel fuel. AT-1 Unit equipment upgrade was performed.
Since the commissioning of the high octane gasoline production complex, all gasoline produced by LLC «KINEF» meets class 5 requirements of the Technical regulations "On the requirements for automotive and aviation gasoline, diesel and marine fuel, jet fuel and fuel oil" as well as the current Euro-5 standards.
LLC «KINEF» plans to continue modernizing its production and increasing oil refining efficiency.
