Air

To protect the atmosphere we continuously monitor and analyse air pollutant emissions by our subsidiaries and affiliates, review trends, and launch emission control initiatives while also encouraging the adoption of the best available solutions to ensure ambient air protection.

NOVATEK has adopted a GHG Emission Management System, which includes a Corporate Standard setting the key principles of, and requirements to, GHG emission management.

The implementation of the system has greatly contributed to global climate change efforts. The prime benefit of the NOVATEK GHG Emission Management System is high accuracy of data on GHG emissions, which is achieved thanks to:
  1. taking into account the hydrocarbon mixture composition at each field;
  2. combination of GHG emission calculation based on material balance and the instrument measurements of GHG emissions;
  3. accounting for all GHG emission sources, including those with contribution of less than 5%;
  4. possibility of obtaining data with precision of less than 1 tonne of CO2 equivalent.

Introduction of the system allowed the Company to identify the sources of GHG emissions ensuring high effectiveness of actions aimed at reducing GHG emission thanks to their targeted application.

To reduce negative impact on the atmosphere we are using the following technologies:

  • COGENERATION. The use of process gases in heating systems. Cogeneration has allowed the Company to eliminate boiler houses in heating systems. Cogeneration fuel savings reach 40% as compared to separate generation of the same amount of power and heat, which leads to significant reductions in combustion emissions, including greenhouse gases.
  • POWER TURBINES. In conformity with best global practices, we use low-emission Euro-turbines.
  • ALTERNATIVE ENERGY SOURCES. Telemechanics and line valve stations information management system is powered by alternative energy sources, including solar panels and wind turbines, which helps reduce indirect GHG emissions.
  • METHANE RECOVERY. Methane is recovered, i.e., recycled by Yamal LNG. Once liquefied, LNG products emit methane vapours (boil-off gas). A vapor recovery system is used to dispose of boil-off gas, which is recycled and can be re-liquefied or used as fuel gas for in-plant consumption. This technology reduces direct gas combustion and consequently pollutant emissions.
  • SMOKELESS FLARES. Our Ust-Luga facility for stable gas condensate and product fractionation and transhipment has a closed-loop flare system to prevent solids emission from combustion products.
  • DEVELOPMENT OF FILLING STATION NETWORK AND CONVERTING VEHICLES TO NATURAL GAS MOTOR FUEL. NOVATEK is an active contributor to the national objective of converting vehicles to natural gas and LPG: the market segment for natural gas as a motor fuel is developing while the network of natural gas retail stations in various Russian regions is expanding. We launched a new business area, namely the construction of LNG retail stations and the subsequent use of LNG as an environmentally friendly motor fuel. Converting a vehicle to run on LNG enables a significant reduction in soot and carbon monoxide emissions compared to conventional fuels (gasoline and diesel).
