Meticulous management of water resources is a major guiding principle in Gazprom Neft’s development of its directly-owned refining facilities — its Moscow and Omsk Refineries. The Moscow Refinery achieved a more than
Installation of key equipment for filtration, disinfection and biological treatment units is currently ongoing as part of building biological treatment facilities at the Omsk Refinery — thanks to which the Omsk Refinery will be able to almost completely transfer to closed-loop water consumption. More than 70% of treated water will be returned to production, reducing the burden on urban wastewater treatment plants. This unique environmentally-friendly project is being implemented as an integral part of the Omsk Refinery’s modernisation programme, and has been included as part of the comprehensive plan underpinning the government’s federal “Clean Air” project.
The Moscow Refinery, in turn, has, thanks to the commissioning of the Biosphere, reduced its consumption of river water more than five-fold in the space of two years. Today almost 80% of water used by the plant is returned to the production cycle, with the remainder sent to city treatment facilities. Wastewater volumes, and the burden on city treatment systems, have seen a more than three-fold reduction since 2017.
The “Biosphere” is an automated multistage system, combining several stages of purification, with all of the plant’s industrial effluents and storm-drainage passing through mechanical, physical—chemical and biological treatment facilities, in turn. After going through each of these stages the water is returned to the production cycle, and the filtered petroleum products recycled. The technologies used in the Biosphere have won a range of industry prizes and awards.
“Gazprom Neft is consistently and systematically working to improve the operational efficiency and environmental friendliness of production processes at its oil refining assets. The company’s project to deploy biological water treatment technologies at its refineries as part of the ‘Biosphere’ complex is something unique to Russia’s oil industry, and something that can be successfully rolled out at production facilities in other industrial sectors.”Anatoly Cherner Deputy CEO for Logistics, Processing and Sales, Gazprom Neft
Gazprom Neft is currently implementing a full-scale modernisation programme at its Omsk and Moscow refineries, involving cumulative investment of more than RUB550 billion. The first stage of modernisation involved the full transition to the exclusive production of Euro-5 fuels. The implementation of the second phase of the modernisation programme is now ongoing, as a result of which the conversion rate and the production of light petroleum products will increase to match the highest international standards.
