As Gazprom Neft actively explored and developed new fields in 2019, the company took measures that enabled it to avoid a year-on-year increase in air pollutant emissions.
Atmospheric emissions are caused mainly by APG flaring, so projects to increase APG utilisation are an important way to reduce emissions.
In order to reduce pollutant emissions, Gazprom Neft is also introducing a large-scale programme to upgrade and overhaul its refining assets, along with other environmental initiatives covering all of its operations.
A significant reduction in SO2 emissions in 2019 was driven by a change in the composition of APG flared at Gazprom Neft Orenburg sites.
In 2019, Gazprom Neft expanded the capabilities of its environmental monitoring system at the Moscow Refinery by commissioning a state-of-the-art mobile laboratory. It is fitted with air sampling equipment, and can assess air quality and record the results in real time. The equipment has been certified and is included in the state register of environmental measuring instruments.
The new laboratory is equipped with fixed analysers and a device for measuring the noise levels.
Precision equipment can perform analysis to detect key types of air pollutants, such as hydrogen sulphide, nitrogen oxide, sulphur dioxide, carbon monoxide, and hydrocarbons. The station can accurately assess the wind speed and direction, and records adverse weather conditions. A connected system for data collection, processing and transmission enables real-time data processing. The laboratory can operate autonomously for an unlimited period of time, and can take air samples while moving.

The Gazprom Neft Omsk Refinery has donated a chromatograph—a modern gas-analysis device—to the Ministry of Natural Resources and the Environment of the Omsk Oblast. This gas analyser, acquired at the request of the government of the Oblast, will be used in a mobile environmental laboratory that Gazprom Net donated to the region in March 2018. This laboratory detects the presence of key types of air pollutants emitted by vehicles, industrial enterprises and boiler houses.
The first phase of construction of the innovative Biosphere treatment facilities was completed at the Omsk Refinery in 2019. Special features of the project include modern gas convection chambers used for off-gas treatment, the ability to reuse recovered petroleum products in the production process, and the nitrogen pads that prevent evaporation into the atmosphere with which the tanks are equipped.
Gazprom Neft is actively participating in the 'Ecology' project initiated by the Russian Government in 2018, put forward under the May Decrees of the President of the Russian Federation. Part of this nation-wide initiative includes the federal 'Clean Air' project, which is designed to reduce emissions by 20% in 12 large industrial cities, including Omsk, where the company operates, by the end of 2024.
In order to carry out the federal 'Clean Air' project, the Russian Government has approved integrated action plans designed to reduce pollutant emissions. These plans include nine upgrade projects launched at the Omsk Refinery, which involve introducing environmental technologies and state-of-the-art treatment facilities, building new units, and decommissioning previous-generation facilities. Gazprom Neft plans to invest over ₽100 billion in these projects.
To support efficient implementation of the federal 'Clean Air' project in the Omsk Oblast, senior executives from Gazprom Neft and high-ranking officials from the Ministry of Natural Resources and Environment of the Russian Federation, the Federal Service for Supervision of Natural Resources (Rosprirodnadzor) and the Government of the Omsk Oblast signed an agreement at the St Petersburg International Economic Forum.
Under the Agreement, a unique wet scrubber system was integrated in a cat-cracking regeneration gas treatment unit at the Omsk Refinery in 2019. This enabled a 100-fold reduction in SO2 emissions and a three-fold reduction in particulate emissions.
