Gazprom Neft’s Omsk Refinery completes first-phase construction of its innovative “Biosphere” water treatment facility

Installation of tanking equipment has now been completed at the Gazprom Neft’s Omsk Refinery’s innovative “Biosphere” water treatment facility. The reservoir block at the future complex will facilitate the preliminary mixing of all of the plant’s production wastewater prior to it being sent for further treatment, with the Biosphere complex delivering almost complete “closed-cycle” water usage, reducing the burden on the city’s wastewater facilities and increasing efficiency in wastewater treatment to 99.9 percent. The construction of the Biosphere forms part of the ongoing full-scale modernisation of the Omsk Refinery, and is a major element in initiatives under the Federal “Clean Air” project. The new water-treatment system is one of Gazprom Neft’s most important environmental projects in the Omsk Region, investment in which currently stands at RUB19 billion. Construction of the Biosphere is expected to be complete by 2021.

The Biosphere facility has been designed as a multi-stage water treatment complex. The Biosphere’s reservoir block comprises 12 100–20,000 cubic-metre-capacity tanks, produced by domestic Russian manufactures to international standards. Following mixing in the reservoir block, the water is sent for mechanical cleaning, during which oil products and other impurities are removed. Thereafter, during physical—chemical cleaning, the water is purified by chemical reagents and sent to a special bio-reactor, where any remnants of oil products are absorbed by microorganisms. In the final stage water is passed through carbon filters, disinfected with ultraviolet light, and returned to the production cycle. Filtered oil products are then sent for processing and recycling.

“The unique Biosphere water treatment complex comprehensively addresses the issues of reducing the environmental impacts of production. Safe and rational water usage is an important factor for any industrial enterprise. In introducing new-generation, environmentally friendly technologies we are conserving resources as well as achieving significant economic benefits.”

Notes for editors

Gazprom Neft is currently involved in a full-scale modernisation programme at its Omsk and Moscow refineries, involving cumulative investment of more than RUB550 billion. The first stage of this programmme has involved the construction and reconstruction of key technological facilities, allowing the complete transition to the production of Euro5 fuels, significantly improving energy efficiency and environmental friendliness in production. The implementation of the second phase of this modernisation programme is now ongoing, as a result of which the refining depth and light product yield are expected to exceed those of leading global producers.

The Federal “Clean Air” project forms part of the national “Ecology” project adopted under a Decree from President of the Russian Federation Vladimir Putin in May 2018. Implementation of various initiatives is expected to lead to a reduction in harmful atmospheric emissions in Bratsk, Krasnoyarsk, Lipetsk, Magnitogorsk, Mednogorsk, Nizhny Tagil, Novokuznetsk, Norilsk, Omsk, Chelyabinsk, Cherepovets, and Chita by 2024, as well as a dramatic reduction in air pollution. Total emissions from transport, power generation and industry are due to see a 20-percent reduction in the Omsk Oblast by 2024.
