Use of water resources
When using water resources, Gazprom Neft seeks to reduce water consumption and discharges in wastewater as well as improve the environmental attributes of water bodies and their coastal areas.
The Company regularly monitors water protection zones as well as surface water, groundwater, and wastewater and assesses the bottom sediment conditions of surface water bodies in the areas where it operates. Scientists from the Polar Research Institute of Marine Fisheries and Oceanography are carrying out comprehensive studies of the water environment as well as key hydrological and hydro-chemical indicators of the water condition near the Prirazlomnaya offshore platform.
Key water resource conservation projects in 2017 included two major projects implemented by the Company as part of the Year of Ecology federal action plan in Russia: the completion of construction on the ‘Biosphera’ treatment plants at the Moscow Oil Refinery and the start of construction on similar facilities at the Omsk Oil Refinery. Investment in the treatment facilities at the Moscow Oil Refinery amounted to RUB 9 billion. The complex consists of a multi-stage wastewater treatment system that includes mechanical, physicochemical, biological, filtration and ultrafiltration stages as well as a reverse osmosis unit. The closed water treatment cycle will make it possible to recycle up to 75% of treated water in production. The technological solutions drastically reduce the total area of the treatment facilities, make them more compact, and ensure the technological stages of water treatment are hermetically sealed.
The Omsk Oil Refinery has begun reorganizing the recycling water supply system in order to meet the production needs of some of the units. Local water units will ensure the uninterrupted operation of base oil production and will also increase the reliability of technological processes, as the water recycling systems will be split up and decentralized.
“The Moscow Oil Refinery is implementing an ambitious programme, which should result in a roughly 75% reduction in the enterprise’s environmental impact. With the introduction of treatment facilities, the refinery will reduce the intake of water from the Moskva River by 60% due to the recycling of treated waters within a closed cycle. This is good news for all residents of the capital and the suburbs”.Sergey Sobyanin Moscow Mayor
